Intracranial hematomas associated with abnormal collateral vessels are observed in certain populations of adult patients with moyamoya disease (MMD). Of these, intraventricular hematomas resulting from rupture of intraventricular aneurysms, which are formed along an abnormal peripheral choroidal artery, are sometimes detected and could be severe. No appropriate treatment option for these ruptured aneurysms has been well established to date. Therefore in this report, we describe the case of an MMD patient with an intraventricular hematoma resulting from a ruptured intraventricular aneurysm arising along the abnormal collateral vessels near the lateral ventricular wall, which was successfully treated using a neuroendoscope. ⋯ Neuroendoscopic aneurysm trapping using aneurysm clips is a treatment option for an intraventricular aneurysm that causes an intraventricular hematoma in patients with MMD. This technique is minimally invasive and offers good visibility of the surgical field.

Cerebral bypass surgery, such as the superficial temporal artery-middle cerebral artery bypass, is one of the essential procedures for cerebral revascularization. However, very narrow or thin blood vessels will increase the risk of anastomotic problems, such as occurs in Moyamoya disease. For such vessels, we have devised a "lifting method" in the recipient arteriotomy. In the present study, we have introduced this novel optional technique and evaluated its effects. ⋯ Use of the lifting method widens and secures the ostium in a recipient vessel and greatly facilitates operability. We have found it to be a foolproof method enabling safe and reliable anastomosis even with narrow or thin vessels.

The role of prophylactic antiepileptic drugs (AEDs) in preventing seizures and/or improving the outcomes after intracerebral hemorrhage (ICH) has remained controversial. The current guidelines have recommended against AED prophylaxis. However, these recommendations were based on older studies that had primarily used phenytoin as the AED of choice. Newer medications, such as levetiracetam, have yet to be extensively studied. ⋯ The administration of, predominantly, levetiracetam for AED prophylaxis after ICH reduced the odds of new seizure events, independently of the admission NIHSS score and the presence of cortical involvement.

Solitary fibrous tumors (SFT) are rare, locally aggressive, mesenchymal neoplasms that pose both diagnostic and operative challenges. In this review of the literature, data were collected from all previously described sellar and suprasellar SFTs to date, with special attention paid to presenting symptoms, surgical technique performed, recurrence status, and adjuvant radiotherapy or chemotherapy, among others. ⋯ SFTs are slow-growing fibroblastic mesenchymal neoplasms that comprise <2% of all intracranial tumors. They are even more infrequently found in the sellar/suprasellar region, with our case being the 12th reported case of such and the first only to use supraorbital craniotomy as a resection strategy. Multimodal therapy consisting of safe gross total resection, radiosurgery, and/or chemotherapy provides the best possible results for these rare and locally aggressive entities.

Comparative Study
Cement augmentation for single level osteoporotic vertebral compression fracture: comparison of vertebroplasty with high viscosity cement and kyphoplasty.
Although the majority of available evidence suggests that vertebroplasty and kyphoplasty (KP) can relieve pain associated with vertebral compression fractures (VCFs) and improve function, evidence of clinical and radiographic outcome in highly viscous cement vertebroplasty (HVC) or KP for the treatment of VCFs is limited. The purpose of this study was to compare the clinical effects between HVC and KP in the treatment of single-level osteoporotic VCFs including radiographic and clinical outcomes. ⋯ Restoring the vertebral height and local kyphotic angle corrections of HVC are similar with those of KP. Additionally, KP is not superior in the leakage rate of bone cement and incidence of adjacent-level vertebra fracture compared to HVC.
