Favorable outcome in patients presenting with aneurysmal subarachnoid hemorrhage (SAH) is determined by several factors. Nevertheless, data on the influence of prior use of oral anticoagulation drugs on functional outcome in patients suffering from SAH are scarce. We therefore analyzed our institutional data. ⋯ Anticoagulation therapy has not been identified as a significant and independent factor influencing functional outcome in patients suffering from SAH. Therefore treatment should not be omitted. Nevertheless, cautious management is necessary in patients with known anticoagulation therapy before SAH.

Case Reports
Trigeminal Ganglioneuroma: A rare cause of trigeminal neuralgia caused by cerebello-pontine angle tumor.
Intracranial ganglioneuromas are very rare benign tumors of neural crest origin and generally arise from the peripheral nervous system or adrenal glands. Very few cases of intracranial ganglioneuroma arising from the trigeminal nerve have been reported in the literature, all in East Asia. ⋯ To the best of our knowledge, this is the sixth case of trigeminal ganglioneuroma; however, it is the first case reported in the United States.

The aim of this article was to analyze risk factors for secondary new vertebral compression fractures (SNVCFs) after percutaneous vertebroplasty in patients with osteoporosis. ⋯ Poor bone mineral content can be a predictive factor of SNVCFs. To prevent SNVCFs, bone cement should be injected as evenly as possible into the vertebral body. Bone cement leakage into the disc space should be avoided.

Case Reports
Delayed development of aneurysms following gamma knife surgery for trigeminal neuralgia: report of 2 cases.
Delayed development of intracranial aneurysms is an extremely rare complication of gamma knife surgery (GKS), with only 6 cases been reported to date. There are no reported cases after GKS performed to treat trigeminal neuralgia (TN). Of the 6 aforementioned cases, none referred to the natural history or pathophysiology of GKS-related intracranial aneurysm formation. ⋯ Long-term observations are necessary after GKS performed for TN owing to the possibility of formation of intracranial aneurysms near the irradiated region.

We describe our single-center experience treating unruptured brain arteriovenous malformations (uBAVMs) with microsurgical treatment. ⋯ Good functional outcome can be achieved by microsurgical resection in S-M grade I and II and selected grade III uBAVMs. Surgical resection for high-grade (grade IV and V) uBAVMs is challenging. A high seizure-free rate can be achieved in patients with initial seizure presentation.
