OBJECTIVETo summarize our experience in the management of adipsic central diabetes insipidus(ADI) accompanied with intracranial calcification.

METHODThe clinical data of one ADI patient accompanied with intracranial calcification who was treated in our hospital since December 2011 were retrospectively summarized.

RESULTSThe 24-hour urine volume was 800 ml. She didn't feel thirsty even with increased plasma sodium concentration(153 mmol/L) and blood osmotic pressure(333 mmol/L) . Combined water deprivation and vasopressin test revealed the diagnosis of central diabetes insipidus. The high intensity signal(on T1-weighted magnetic resonance imaging) in the posterior lobe of pituitary gland was found. Computed tomography showed calcifications in the bilateral basal ganglia.Serum cytomegalovirus IgG was positive. She was treated with desmopressin and asked for regular water intake regardless of the adipsia. The plasma sodium concentration was still below 150 mmol/L during the 4-month follow-up.

CONCLUSIONSRoutine adipsia evaluation and combined water deprivation and vasopressin test are critical for the diagnosis and treatment of ADI. Past insidious intracranial cytomegalovirus infection may explain the cause of ADI and calcification.

Central diabetes insipidus (DI), characterized by unexpected fatal hypernatremia, is a rare complication after successful cardiopulmonary resuscitation with therapeutic hypothermia, but may be potentially fatal if recognition is delayed. We describe here a patient who experienced cardiac arrest due to a pulmonary embolism, followed by successful resuscitation after induction of therapeutic hypothermia. The patient, however, suddenly developed unexpected hypernatremia with increased urine output and was diagnosed with central DI as a complication of cerebral edema, and eventually died. Our findings suggest that central DI should be considered as a possible complication following unexpected hypernatremia with increased urine output during therapeutic hypothermia and that desmopressin acetate should be used to treat central DI.

Diabetes insipidus (DI) is characterized by excessive urination and thirst. This disease results from inadequate output of antidiuretic hormone (ADH) from the pituitary gland or the absence of the normal response to ADH in the kidney. We present a case of transient central DI in a patient who underwent a cardiopulmonary bypass (CPB) for coronary artery bypass grafting (CABG). A 44-yr-old male underwent a CABG operation. An hour after the operation, the patient developed polyuria and was diagnosed with central DI. The patient responded to desmopressin and completely recovered five days after surgery. It is probable that transient cerebral ischemia resulted in the dysfunction of osmotic receptors in the hypothalamus or hypothalamus-pituitary axis during CPB. It is also possible that cardiac standstill altered the left atrial non-osmotic receptor function and suppressed ADH release. Therefore, we suggest that central DI is a possible cause of polyuria after CPB.

We report a rare case of diabetes insipidus following fire burn injury. Meticulous fluid balance and the use of carbamazepine resulted in her survival.

OBJECTIVETo analyze the factors contributing to the occurrence of diabetes insipidus after operations for craniopharyngiomas.

METHODSA total of 121 cases of diabetes insipidus following surgeries for craniopharyngiomas were retrospectively analyzed and the factors associated with postoperative diabetes insipidus were analyzed.

RESULTSThe incidence of diabetes insipidus was 27.3% (33/121 cases) before the operation, 89.9% (107/1119) early after the operation and 39.8%(37/93) in later stages after the operation. The occurrence of early postoperative diabetes insipidus showed a significant relation to the classification and calcification of the craniopharyngioma. Patients with supradiaphragmatic and extraventricular tumors had the lowest incidence of postoperative diabetes insipidus. Late postoperative diabetes insipidus was closely correlated to such factors as age, classification of craniopharyngioma, and intraoperative treatment of the pituitary stalk, but not to the scope of tumor resection or tumor calcification. Late diabetes insipidus was more frequent in children and patients with severed pituitary stalk. The incidence of late postoperative diabetes insipidus was significantly higher in patients with supradiaphragmatic and extra-intraventricular tumors than in those with tumors beneath the diaphragma sellae and extraventricular tumors.

CONCLUSIONSPostoperative diabetes insipidus following surgeries for craniopharyngiomas is closely related to the tumor classification, calcification and pituitary stalk protection.

OBJECTIVETo study the prevention and treatment of postoperative diabetes insipidus after removal of pituitary tumor through transsphenoidal operation, to decrease the incidence of postoperative complications and improve the treatment of pituitary tumor.

METHODSThe clinical data of 86 cases of transsphenoidal resection of pituitary tumor in recent 8 years were retrospectively reviewed, including 35 endoscopic operation and 51 microscopic operation. The incidence, prevention and treatment of diabetes insipidus were statistically analysed.

RESULTSThere were 18 cases of postoperative diabetes insipidus in total of 86 operations, including 15 acute cases, 3 delayed cases. Twelve were temporary , which recovered within 1 week. After prompt treatment, 14 recovered within 1 week, 4 recovered within 2 weeks. No persistent diabetes insipidus was found.

CONCLUSIONSThe key points to prevent postoperative diabetes insipidus lay in the improvement of operative skills, careful protection during operation and avoidance of unnecessary injury. In case of diabetes insipidus occurred, rational use of antidiuretics and correction of electrolyte balance were effective in the treatment of postoperative diabetes insipidus.

Metastatic brain tumors from gastric cancer are extremely rare. A 61-year-old Korean woman, initially presenting with polydipsia and polyuria, was found to have metastatic lesions in the brain by MRI. We performed several diagnostic procedures to determine the origin of the brain metastases. She was revealed to have a soft tissue mass of the right adrenal gland and fungating ulcers in the stomach. Histologic studies of both the adrenal gland mass and gastric tissues revealed malignant tumors composed of anaplastic cells. Based on the electron microscopy study, the malignant tumor of the right adrenal gland was a metastatic lesion from the anaplastic carcinoma of stomach. Therefore, the malignant tumors of the brain were assumed to have originated from the gastric cancer. This case report is presented to make clinicians aware of the possibility that diabetes insipidus (polydipsia) may present as an initial manifestation of brain metastases.

Lymphocytic hypophysitis is a rare inflammatory disorder in the pituitary gland. The lesion is usually confined to the adenohypophysis. Although the involvement of the posterior pituitary gland or the stalk is rare, such patients with diabetes insipidus have been reported. Surgery has been used to make the definitive diagnosis. Recent studies suggest, however, that the pathologic diagnosis may not be necessary always. We reported a case of Lymphocytic hypophysitis managed by methylprednisolone pulse therapy. A 50-year-old premenopausal woman with Lymphocytic hypophysitis and diabetes insipidus was treated with methylprednisolone pulse therapy. Her adenopituitary lesion disappeared and the diabetes insipidus resolved. The optimal management for patients with lymphocytic hypophysitis may be the high index of the suspicion prior to the extensive surgical resection. In addition, methylprednisolone pulse therapy may improve the clinical and MRI findings.
