Meningioma is one of the most common types of benign primary brain tumors in older adults, and multiple meningiomas are reported in fewer than 1% to 10% of cases. However, there is no definitive treatment guideline for patients with multiple meningiomas. An 80-year-old man presented with abruptly impaired cognition and was found to have two distinct meningiomas located in the temporal and frontal lobes. A single frontotemporal craniotomy was performed to remove both tumors. Pathological analysis revealed different subtypes and World Health Organization grades for each mass. The patient showed symptomatic improvement, experienced no postoperative complications, and exhibited no signs of recurrence during a 1-year follow-up period with evaluations at 3-month intervals. Despite the absence of a standard treatment for multiple meningiomas, surgical resection in a single procedure is feasible in selected patients.

Objective: Decompression with instrumented fusion is a common approach for treating spinal metastatic disease. However, in many cases, poor bone quality and compromised general condition increase the likelihood of mechanical failure and other complications. This study investigated complications, including those related to surgery, following decompression and fusion in patients with spinal metastatic disease. Methods: A study at a single tertiary medical center focusing on surgical details and perioperative complications was performed on 35 patients who underwent spinal surgery due to metastatic spinal disease based on a review of a prospective database. Data on patients' underlying conditions and the status of the primary tumors were collected, and various complications that occurred within the first month after surgery were analyzed. Results: During the study, 35 patients (mean age, 66.5 years; 26 men) were enrolled. The most frequent primary cancers were lung (34%) and prostate cancer (17%), followed by liver and breast cancer and others. The overall complication rate was 37% (14% surgery-related complications, 23% general complications). In all cases, surgery was performed due to lower extremity weakness, and 59% of patients showed improvements in motor function after surgery. Furthermore, 23% of patients regained the ability to walk. Conclusion Surgery for spinal metastasis is frequently performed as an emergency due to the severity of symptoms such as lower extremity weakness. Despite a high risk of acute complications, the procedure has significant benefits, including improvement in weakness and recovery of walking ability. Therefore, proactive treatment using appropriate surgical techniques is recommended.

Background: Volume overload is associated not only with clinical manifestations but also with poor outcomes of heart failure (HF). However, there is an unmet need for effective methods for serial monitoring of volume status during HF hospitalization. The aim of this study was to evaluate the prognostic implication of serial measurement of bioelectrical impedance analysis (BIA) in patients hospitalized with acute HF. Methods: This study is a retrospective observational study and screened 310 patients hospitalized due to acute decompensated HF between November 2021 and September 2022. Among them, 116 patients with acute HF who underwent BIA at the time of admission and at discharge were evaluated. We investigated the correlation between change of BIA parameters and the primary composite outcome (in-hospital mortality or rehospitalization for worsening HF within one month). Results: The median (interquartile range) age was 77 years (67–82 years). The mean left ventricular ejection fraction was 40.7 ± 14.6% and 55.8% of HF patients have HF with reduced ejection fraction. The body water composition (intracellular water [ICW], extracellular water [ECW], and total body water [TBW]) showed a statistically significant correlation with body mass index and LV chamber sizes. Furthermore, the ratio of ECW to TBW (ECW/TBW), as an edema index showed a significant correlation with natriuretic peptide levels. Notably, the change of the edema index during hospitalization (ΔECW/TBW) showed a significant correlation with the primary outcome. The area under the curve of ΔECW/TBW for predicting primary outcome was 0.71 (95% confidence interval [CI], 0.61–0.79; P = 0.006). When patients were divided into two groups based on the median value of ΔECW/TBW, the group of high and positive ΔECW/TBW (+0.3% to +5.1%) had a significantly higher risk of the primary outcome (23.2% vs. 8.3%, adjusted odds ratio, 4.8; 95% CI, 1.2–19.3; P = 0.029) than those with a low and negative ΔECW/TBW (−5.3% to +0.2%). Conclusion BIA is a noninvasive and effective method to evaluate the volume status during the hospitalization of HF patients. The high and positive value of ΔECW/TBW during hospitalization was associated with poor outcomes in patients with HF.

We report a case of bilateral femur fracture which may have resulted in part from long-term administration of antipsychotic agents. A 43-year-old female patient with pain in both thighs visited our clinic. We conducted Xray and magnetic resonance imaging (MRI) examinations which revealed bilateral femur fractures. The right proximal femur had a complete fracture, and the left proximal femur had an incomplete fracture, both of which were in the subtrochanteric area. The patient was treated by intramedullary nailing in the right femur. Laboratory analysis showed hyperprolactinemia and hypogonadism. Bone mineral density analysis showed osteoporosis. Antipsychotic drug-induced hyperprolactinemia is a well-known phenomenon. Despite concerns about hyperprolactinemia induced osteoporotic fracture in patients treated with only prolactin-elevating medications, the issue has not been extensively studied. If hyperprolactinemia patients suffer from uncontrolled pain, we recommend MRI examination as surgeons should be aware of the possibility of osteoporotic fracture induced by hyperprolactinemia.

Central venous catheterization is a routinely performed procedure in clinical practice. While cerebral air embolism after the removal of the central venous catheter is very rare, it is one of the most serious complications that can lead to fatal outcomes. In this report, we present a rare case of a cerebral air embolism after the removal of the central venous catheter in a patient with a patent foramen ovale.

Accessory muscles located in the region of the popliteal fossa are very rare. MRI scan performed in a 52-year-old man with right knee pain revealed an anomalous muscle in the region of the popliteal fossa. Considering the muscle originated from the medial side of the lateral head of the gastrocnemius muscle and attached to the posteromedial articular capsule of the knee joint, it is consistent with the accessory popliteus muscle, previously reported. To our best knowledge, MRI finding about the accessory popliteus muscle has been reported in only one case. We present a case of the accessory popliteus muscle incidentally identified on MRI.

PURPOSE: This study investigated the correlative relationship between metabolic parameters estimated from dual time point 2-deoxy-2-[¹⁸F] fluoro-D-glucose (¹⁸F-FDG) positron emission tomography/computerized tomography (PET/CT) and the clinical tools predicting the outcome of a lymphoma. We also measured metabolic and volumetric alterations between early and delayed ¹⁸F-FDG PET/CT in patients with high grade lymphoma (HGL).METHODS: The samples were 122 lymph nodes and extralymphatic lesions from 26 patients diagnosed with HGL. All patients were applied to the International Prognostic Index (IPI), Ann Arbor stage, and revised IPI as clinical prognostic parameters. ¹⁸F-FDG dual time point PET/ CT (DTPFP) consisted of an early scan 1 h after ¹⁸F-FDG injection and a delayed scan 2 h after the early scan. Based on an analysis of DTPFP, we estimated the standardized uptake value (SUV) of tumors from the early and delayed scans, retention index (RI) representing the percentage change between early and delayed SUV, and metabolic volume different index (MVDI) calculated using metabolic tumor volumes (MTV).RESULTS: RI(max) showed a multiple positive correlative relationship with stage and IPI in lesion-by-lesion analysis (p < 0.01). In the case of IPI, the high risk group exhibited higher RI(max) than the low risk group (p = 0.004). In the case of revised IPI, the RI(max) of the low risk group were significantly lower than the intermediate and high risk groups, respectively (p < 0.01). The MVDIs of the best outcome group were decreased in comparison to the moderate outcome group (p = 0.029). There was a significant negative correlative relationship between RI(max) and MVDI, and the inclinations for decreased MVDIs were slightly associated with increased RIs.CONCLUSIONS: RI(max) extracted from DTPFP had a significant relationship to extranodal involvement, staging, IPI, and revised IPI. MVDI showed significant negative correlation with RI(max). Further large scale studies are warranted to support and extend these preliminary results.

PURPOSE: We compared visible blood loss and calculated blood loss after bipolar hemiarthroplasty in femoral neck fracture, and evaluated correlation between blood loss and its risk factors. MATERIALS AND METHODS: A total of 356 patients who underwent bipolar hemiarthroplasty in femoral neck fracture between 2004 and 2010 were enrolled in this study. The total blood loss was calculated using the formula reported by Mercuiali and Brecher. We analyzed several factors, including gender, age, body mass index (BMI), anesthesia method, cardiovascular and cerebrovascular disease, preoperative anemia, American Society of Anesthesiologists (ASA) score, use of cement, and use of antithrombotic agents. RESULTS: Total calculated blood loss(1,408+/-72 ml) differed significantly from visible blood loss(980+/-102 ml). In addition, calculated blood loss differed between risk factors(1,526+/-369 ml in cardiovascular disease, 1,588+/-279 ml in general anesthesia, 1,645+/-920 ml in obesity, and 1,605+/-439 ml in use of antithrombotic agents). CONCLUSION: Total calculated blood loss was much greater than visible blood loss. Patients with risk factors such as cardiovascular disease, obesity, use of antithrombotic agents, and general anesthesia should be treated with care in order to reduce blood loss.

Superior vena cava syndrome (SVCS) is usually caused by extrinsic compression or invasion of the superior vena cava (SVC) by malignant tumors involving mediastinal structures. Although thymomas are well-known causes of SVCS, cases of SVCS caused by malignant thymomas protruding into adjacent vessels draining the SVC with thrombosis have been very rarely reported worldwide. We experienced a 39-year-old female patient with SVCS that developed after the direct invasion of the left brachiocephalic vein (LBCV) and SVC by an anterior mediastinal mass with a high maximum standardized uptake value on the chest computed tomography (CT) and positron emission tomography-CT. Based on these results, she underwent en bloc resection of the tumor, including removal of the involved vessels, and was eventually diagnosed as having a type B2 thymoma permeating into the LBCV and SVC. We present this case as a very rare form of SVCS caused by an invasive thymoma.

While Raoultella planticola is a rare cause of human infection, we experienced a case of severe cholangitis caused by R. planticola. A 75-year-old male patient with cancer of the pancreatic head was admitted and found to have cholangitis. Following performance of percutaneous transhepatic biliary drainage for decompression and initiation of empirical antibiotics with cefotaxime and metronidazole. R. planticola, which was susceptible to cefotaxime, was isolated from both bile and blood. Despite administration of prompt and appropriate antibiotic therapy, the patient died 10 days after admission. We herein describe the first case of cholangitis caused by infection with R. planticola.
