Introduction: Pheochromocytoma is a catecholamine-secreting adrenal tumor associated with major perioperative hemodynamic instability. When concurrent major pelvic pathology requires surgery, operative planning becomes particularly challenging. We describe the successful single-stage management of pheochromocytoma and a giant uterine fibroid, highlighting the importance of multidisciplinary coordination and perioperative optimization. Case: A 49-year-old female with symptomatic uterine fibroid was found to have proliferative endometrium on a pipelle biopsy. Computed tomography (CT) abdomen incidentally detected a right adrenal mass alongside a large posterior uterine fibroid (11.9 × 17.4 × 14.6 cm). CT adrenal protocol demonstrated a heterogeneously enhancing right adrenal mass (6.9 × 6.9 × 9.6 cm) with high unenhanced attenuation. Biochemical evaluation revealed markedly elevated 24-hour urinary metanephrine (4.7× upper limit) and normetanephrine (2.4× upper limit). Following multidisciplinary discussions, a single-stage surgical approach was planned after careful assessment of feasibility and perioperative risk in view of the uncertain malignant potential of the pelvic mass and to minimize repeated exposure to anesthesia. Preoperative optimization included transitioning from terazosin to phenoxybenzamine, with subsequent addition of bisoprolol for hemodynamic control. The operative strategy prioritized pheochromocytoma resection first, given its potential for significant hemodynamic instability. Progression to hysterectomy was contingent upon achieving adequate intraoperative hemodynamic stability following adrenalectomy, with continuous reassessment by the anesthetic and surgical teams. Right adrenalectomy was performed first, followed by total abdominal hysterectomy with bilateral salpingooophorectomy. Significant hemodynamic lability occurred during tumor manipulation, with hypertensive surges managed using sodium nitroprusside and remifentanil infusions. Following adrenal vein ligation and tumor removal, hypotension was managed with noradrenaline and additional adrenaline support as required. Total operative time was approximately 6 hours. Postoperatively, transient noradrenaline support was required but was rapidly weaned as hemodynamic stability was achieved. Conclusion Single-stage adrenalectomy and major pelvic surgery can be safely performed in selected patients with pheochromocytoma when guided by meticulous preoperative optimization, clear intraoperative sequencing, and close multidisciplinary coordination.

Introduction: Adrenal incidentalomas are increasingly detected with the widespread use of imaging, whereby the large or heterogeneous lesions often raise concern for adrenocortical carcinoma (ACC). However, certain rare benign and infectious conditions may closely mimic malignant features, posing a diagnostic challenge. Case: A 64-year-old female with diabetes mellitus, hypertension, and dyslipidemia was noted to have progressively rising alkaline phosphatase during routine follow-up. She had non-specific gastrointestinal symptoms. A computed tomography abdomen pelvis showed a large, lobulated mass at the left flank, likely of adrenal origin. An adrenal protocol computed tomography revealed a large, heterogeneously enhancing left suprarenal mass measuring 10.7 × 10.3 × 10.7 cm, with a plain-phase attenuation of +81 Hounsfield Unit and absolute (28%) and relative (18%) washout. The right adrenal gland was normal, with no evidence of distant metastasis. Hormonal evaluation showed normal 24-hour urinary metanephrines, excluding pheochromocytoma. The overnight dexamethasone suppression test demonstrated cortisol of 89 nmol/L, suggestive of mild autonomous cortisol secretion, without clinical features of overt hypercortisolism. DHEA was low (0.371 µmol/L), and adrenocorticotropic hormone was suppressed (1.26 pg/mL). Evaluation for primary aldosteronism was not done due to the absence of resistant hypertension or hypokalemia. The gonadotropin profile was consistent with postmenopausal status (follicle-stimulating hormone (89 IU/L) and luteinizing hormone (28.9 IU/L) with low estradiol. The patient underwent open left adrenalectomy. Histopathology revealed an adrenal cavernous hemangioma with extensive hemorrhage and infarction, alongside necrotizing granulomatous inflammation with numerous intracellular fungal organisms and narrow-based budding yeast forms, highly suggestive of histoplasmosis, with no evidence of malignancy. She was subsequently comanaged with infectious disease team and commenced on intravenous amphotericin B. Conclusion This is a rare coexistence of an adrenal hemangioma and histoplasmosis, presenting as a large adrenal mass mimicking ACC. The limitations of imaging in differentiating benign from malignant adrenal lesions are revealed and emphasize the role of histopathological confirmation. Increased awareness of such entities can support the diagnosis and management.

Introduction: Primary bilateral macronodular adrenal hyperplasia (PBMAH), characterized by bilateral adrenal macronodules >1 cm, is a rare genetic disease contributing to <2% of Cushing syndrome. Case: A 56-year-old male with underlying diabetes mellitus and hypertension presented with worsening proximal muscle weakness. Detailed neurological assessment was unremarkable. Re-assessment revealed more apparent cushingoid features, prompting referral to endocrinology. Basal cortisol was markedly elevated at 957 nmol/L (145.4– 619.4 nmol/L). Unsuppressed cortisol after 1 mg overnight dexamethasone and low-dose dexamethasone test confirmed Cushing Syndrome. Suppressed adrenocorticotropic hormone (ACTH <0.33 pmol/L) suggested autonomous cortisol secretion from adrenal glands. Computed tomography adrenal reported massively enlarged hypodense multinodular adrenal glands of varying sizes. Oral ketoconazole, an adrenal steroidogenesis inhibitor, was initiated. Despite careful titration to keep serum cortisol 400–500 nmol/L, he experienced glucocorticoid withdrawal syndrome. Bilateral adrenalectomy was planned but deferred as he continued to lose weight despite persistent hypercortisolism. Extensive investigations were conducted for possible opportunistic infections or malignancy. His chest X-ray revealed a suspicious right lung cavity. Positive serum galactomannan and bronchial alveolar lavage galactomannan suggested pulmonary aspergillosis. Voriconazole was introduced, with drug-drug interaction judiciously addressed. He underwent bilateral adrenalectomy and required lifelong glucocorticoid and mineralocorticoid replacement. Histopathological report confirms bilateral macronodular adrenocortical disease. A referral to a genetic clinic was made to explore the potential hereditary basis. Conclusion PBMAH is a highly heterogeneous disease with variable presentation and a wide spectrum of hypercortisolism. Definitive management remained controversial and individualized. Multidisciplinary discussion is crucial, and genetic study is highly recommended for long-term prognostication and familial screening.

Introduction: Diabetes literacy represents personal knowledge and competencies related to diabetes mellitus (DM) among people living with DM (PLWD). It is a crucial component for optimizing care and empowering effective selfmanagement. Methodology: A cross-sectional study was conducted at Hospital Tuanku Ja’afar Seremban (HTJS) and Klinik Kesihatan Seremban (KKS) using a validated simplified Diabetes Knowledge Test (DKT). DKT assessed understanding in six domains, namely, awareness, lifestyle modification, diet and monitoring, general knowledge, preventive screening, and insulin. A score of >75% was classified as adequate diabetes literacy. Significant predictive factors identified from univariate Pearson Chi Square were further analyzed using multivariate logistic regression. Results: A total of 250 PLWDs, with equal contribution from each centre, were recruited with a mean (SD) age of 50.3 (13.6) years, 58.4% female, and 43.2% Malays. A total of 21.2% demonstrated adequate diabetes literacy. The results demonstrated the highest proficiency in the preventive screening domain (92.6%) and the lowest in the awareness domain (50.2%). Unemployed PLWDs had significantly lower odds of adequate diabetes literacy (odds ratio [OR] = 0.20, p = 0.010). Similarly, PLWDs with hemoglobin A1c levels >10% exhibited approximately 2.6-fold lower odds of adequate diabetes literacy. In contrast, PLWDs who reported healthcare personnel as their primary source of diabetes-related information had significantly higher odds of adequate literacy (OR = 1.59, p = 0.017). No significant association was demonstrated between diabetes literacy and frequency of hospital admissions, medication adherence, and diabetes-related target organ damage Conclusion Diabetes literacy among PLWD in HTJS and KKS is suboptimal, with notable gaps in awareness of the disease. Targeted, culturally tailored education strategies are essential to address these disparities and to empower them for effective diabetes self-management.

Introduction: The 2021 IDF-DAR risk calculator had been previously evaluated in multiple studies and subsequently widely accepted and applied in clinical practice as a practical standardized tool for patient risk stratification. Recently updated, the 2026 IDF-DAR Risk calculator enables a more individualized, evidence-related evaluation of patientrelated and disease-related risk factors, incorporating modern diabetes technologies, including continuous glucose monitoring (CGM), automated insulin delivery (AID) systems, and advanced insulin formulations to enhance risk stratification. This tool allows medical professionals to tailor Ramadan practices based on overall factors toward promoting safe fasting. Methodology: This prospective multicentre observational study recruited adults with Type 1 and Type 2 diabetes attending public hospitals nationwide. People with diabetes (PwD) intending to perform Ramadan fasting were invited to participate and assessed using the 2026 IDF-DAR Risk Calculator in the 6-week pre-Ramadan period between 30th January and 19th March 2026. Results: A total of 458 PwD were evaluated and stratified into low (15.7%), moderate (41%), and high risk (43.3%) categories. Most participants had Type 2 diabetes (83.6%), with 60.3% having a disease duration exceeding 10 years and 43% exhibiting poor glycemic control (hemoglobin A1c >9%). Insulin therapy was used by 76.4% of participants, including two individuals with Type 1 diabetes using AID systems. Most participants reported no recent hypoglycemia (76.4%), 81.0% performed glucose monitoring, and 3.3% used CGM. Severe comorbidities were uncommon, with 1.1% having unstable macrovascular disease and 4.4% advanced chronic kidney disease (estimated glomerular filtration rate <30). Notably, 72.2% received structured Ramadan education. Conclusion Majority of PwD attending tertiary diabetes clinics were in the moderate- to high-risk category and intended to fast despite medical advice against fasting in some cases. Although most participants were on insulin therapy, hypoglycemia was low in the pre-Ramadan period. Integration of modern technologies, advanced insulin therapies, and structured education may support safer fasting practices.

Introduction: Severe hypertriglyceridemia, though rare in pregnancy, is a clinically significant condition that poses substantial maternal and perinatal risks. Case: We present a case of a 42-year-old pregnant female with class I obesity and pre-existing type 2 diabetes mellitus, with a booking hemoglobin A1c 12.1%. Her poorly controlled diabetes was complicated by nephrotic syndrome, with a 24-hour urine protein 4.9 g/day. She also had bilateral diabetic retinopathies requiring multiple sessions of panretinal photocoagulation. Throughout the pregnancy, her triglycerides rose progressively, peaking at 30 mmol/L by 33 weeks. Investigations revealed normal thyroid function, urea 4.8 mmol/L, creatinine 66 umol/L, and albumin 26 g/dL. The patient was hospitalized at 33 weeks of gestation and started on an intravenous insulin infusion along with a very low-fat, low-carbohydrate diet prescribed by a dietitian. Pulmonary embolism was diagnosed during evaluation for maternal tachycardia, and subcutaneous enoxaparin was initiated. One week after admission in 35 weeks of gestation, the baby was delivered via emergency Caesarean section due to fetal distress. The baby was small for gestational age, with a birth weight of 1.9 kg, below the 10th percentile for gestational age, and required admission to the neonatal intensive care unit with oxygen support for pneumonia-related respiratory distress. Post-delivery, intravenous insulin infusion and dietary control were continued, reducing her triglyceride level to the lowest level of 8.3 mmol/L. Both mother and baby were discharged well. Lipid-lowering agents such as rosuvastatin and fenofibrate were started after breastfeeding stopped, aiming to normalize her triglyceride levels. Conclusion Hypertriglyceridemia in this patient was the result of uncontrolled diabetes mellitus with nephrotic-range proteinuria. Severe hypertriglyceridemia can cause acute pancreatitis and/or hyperviscosity syndrome, both of which are life-threatening to the mother and baby. Thus, rapid reduction of triglyceride levels is crucial. This case highlights the importance of achieving good diabetes control prior to pregnancy, with strict adherence to treatment and enhanced patient education.

Introduction: Diabetic ketoacidosis (DKA) and thyroid storm are individually rare but potentially fatal endocrine crises in pregnancy. Each carries significant maternal and fetal morbidity, with mortality risk compounded when they occur concomitantly. Physiological and pharmacokinetic changes of pregnancy, combined with overlapping symptoms, necessitate urgent treatment strategies. Case: A 29-year-old G2P2 female at 29 weeks’ gestation, with poorly controlled type 2 diabetes mellitus (hemoglobin A1c 8.1%) on a basal–bolus insulin regimen and Graves’ disease managed with carbimazole, non-adherent to medications, presented with fever, vomiting, and dyspnea. On examination, she was tachycardic (HR 138 bpm), hypotensive (BP 94/60 mmHg), and hypoxic. Laboratory investigations revealed hyperglycemia (glucose 27.1 mmol/L), severe metabolic acidosis (pH 7.02, bicarbonate 4.9 mmol/L), and elevated serum ketones (4.6 mmol/L), consistent with DKA. Thyroid function tests showed suppressed thyroid-stimulating hormone (<0.005 mIU/L) and elevated free T4 (28.2 pmol/L), with a Burch–Wartofsky score of 70. Unfortunately, intrauterine fetal demise was confirmed upon the patient’s presentation to the emergency department. She was intubated and admitted to the intensive care unit, receiving fluid resuscitation judiciously according to the DKA regimen, with frequent assessment of volume status. Intravenous insulin and potassium supplements were commenced concurrently. Metabolic stabilization was achieved within 24 hours. Carbimazole, propranolol, Lugol’s iodine, and intravenous hydrocortisone were started for treatment of thyroid storm. A breech-assisted vaginal delivery was performed, and her postpartum course was uneventful. Conclusion The case reveals the catastrophic potential of concurrent DKA and thyroid storm in pregnancy, where rapid maternal deterioration and poor fetal outcomes can occur despite timely intervention. High clinical suspicion, early biochemical confirmation, and coordinated multidisciplinary management are vital. Precipitating factors, particularly medication non-adherence, must be addressed through intensive patient education and structured follow-up to prevent recurrence.

Introduction: Primary hyperparathyroidism (PHPT) is frequently asymptomatic or detected incidentally; however, delayed diagnosis may lead to severe skeletal complications. Early recognition is essential, as timely identification and management of parathyroid disease can prevent significant morbidity, although diagnosis may be challenging when clinical and imaging findings are inconclusive. Case: A 46-year-old female with severe bilateral hearing impairment presented to the orthopedic clinic with 3 years’ history of bilateral knee pain and was found to have a right intertrochanteric femur fracture following minimal trauma. She was referred for evaluation of suspected secondary osteoporosis. She has had intermittent constipation and long-standing oligomenorrhea since menarche. There was no history of childhood fractures or use of medications affecting bone metabolism. Examination revealed bilateral knee bowing. Initial evaluation considered metabolic bone disease, including Paget’s disease; however, skeletal survey showed no features suggestive of Paget’s disease or multiple myeloma. Biochemical investigations demonstrated persistent hypercalcemia (2.65–3.1 mmol/L) with inappropriately elevated intact parathyroid hormone (peak 7.62 pmol/L), consistent with PHPT. Serum phosphate was low-normal. Concomitant vitamin D deficiency (25-OH vitamin D 34.46 nmol/L) improved following replacement. Bone mineral density confirmed severe osteoporosis (lumbar spine T-score −5, z-score -4.1); (forearm −6.7, z-score -6.1) reflecting prolonged untreated disease. Neck ultrasound demonstrated a mixed solid-cystic lesion posterior to the right thyroid lobe, suggestive of a parathyroid adenoma. The TC-99 m Sestamibi scan showed no definite focal uptake. However, subsequent SPECT-CT revealed focal tracer uptake at the posterior right thyroid gland, consistent with a hyperfunctioning parathyroid gland. Parathyroidectomy was done. Postoperatively, the calcium level normalized. Conclusion Severe osteoporosis and fragility fracture occur, reflecting prolonged exposure to excess parathyroid hormone and significant skeletal morbidity. Early biochemical evaluation in unexplained severe osteoporosis is essential, as timely diagnosis and definitive management of parathyroid disease are critical to halt ongoing bone loss and prevent irreversible complications.

Introduction: Incidental hyperparathyroidism with hypercalcemia is not uncommon. However, parathyroid carcinoma is an extremely rare endocrine malignancy, accounting for less than 1% of cases of primary hyperparathyroidism. Case: A 57-year-old Malay female with well-controlled type 2 diabetes was incidentally found to have hypercalcemia during hospitalization for pyelonephritis. She was asymptomatic, with no history of calcium supplementation or family history of endocrine disorders. Physical examination revealed no obvious neck swelling, and other systemic examinations were unremarkable. Investigations showed elevated serum calcium (2.87–3.4 mmol/L), low phosphate (0.34–0.76 mmol/L), and elevated intact parathyroid hormone (iPTH) (6.81 pmol/L). Her 25-OH vitamin D was deficient (45.58 nmol/L). Ultrasound of the neck revealed a solid lesion (1.6 × 2.0 × 2.8 cm) posterior to the right thyroid lobe with bilateral thyroid nodules, with the highest TR4, and normal cervical lymph nodes. Sestamibi scan showed multinodular goiter with cold nodules in bilateral thyroid lobes and a soft tissue lesion posterior to the right thyroid lobe. Subsequently, she underwent right hemithyroidectomy with intraoperative nerve monitoring and right inferior parathyroidectomy with intraoperative iPTH monitoring; the intraoperative iPTH level dropped appropriately from 24 to 2.4 pmol/L. Histopathological examination of the excised right parathyroid gland revealed parathyroid carcinoma, while the right thyroid lobe showed nodular hyperplasia. Postoperatively, calcium and iPTH levels normalized, and she remained well under follow-up. Conclusion Parathyroid carcinoma typically presents with markedly elevated calcium and iPTH levels, often alongside a palpable neck mass. However, in this patient, serum iPTH was only slightly above the upper limit of normal, with tumor size less than 3 cm, no lymph node or surrounding structures involvement from pre-operative evaluation imaging. This highlights the variability in both physical and biochemical presentations of parathyroid carcinoma and the challenges in distinguishing it from benign parathyroid tumors preoperatively.

Introduction: Pituitary apoplexy is an acute endocrine emergency, as early recognition may influence the outcomes, often presenting with sudden headache, visual disturbances, ocular palsies, vomiting, or altered consciousness. Given that urgent surgical decompression is a common management, emerging evidence supports corticosteroid therapy in our patient with significant neuro-ophthalmic deficits. Case: A 65-year-old male with hypertension, dyslipidemia, type 2 diabetes mellitus, chronic kidney disease stage III, and ischemic heart disease presented with a 4-day history of fever, vomiting, bifrontal headache, and generalized abdominal pain. Initially, he was treated for presumed intraabdominal sepsis. On day 3 of admission, he developed acute right-sided complete ptosis with ophthalmoplegia involving cranial nerves III, IV, and VI. Prior to that, he had also reduced morning erections for 6 months before presentation. Biochemical evaluation revealed markedly reduced total testosterone (0.33 nmol/L) with inappropriately low–normal gonadotropins (luteinizing hormone 1.5 IU/L, follicle-stimulating hormone 2.3 IU/L), in keeping with secondary hypogonadism. Adrenocorticotropic hormone was suppressed, indicating secondary adrenal insufficiency. Thyroid function was preserved. Overall findings suggested partial hypopituitarism. Magnetic resonance imaging confirmed a cystic pituitary lesion measuring 1.4 × 2.6 × 1.8 cm with cavernous sinus involvement and features of pituitary apoplexy. His Pituitary Apoplexy Score was 4. He was offered surgical intervention but was not keen. He was treated with intravenous hydrocortisone, with rapid clinical improvement, including near-complete resolution of right eye ptosis and restoration of extraocular movements within 3 days, and was able to recover without surgery. The hydrocortisone was gradually tapered, and the patient was discharged well with Endocrine follow-up. Conclusion Timely corticosteroid therapy alone can result in rapid, near-complete neurological recovery in pituitary apoplexy, even with multiple cranial nerves involvement. In carefully selected patients without visual field compromise, conservative management may safely obviate the need for urgent surgical intervention, emphasizing the importance of early recognition and individualized treatment strategies.
