We report a case of cerebellar schwannoma in a 64-year-old woman. The tumor was defined on computed tomographic and magnetic resonance imaging scans and confirmed on surgery. The solid part of the tumor appeared to be derived from the inferior vermis of the cerebellum, the cystic part extending toward the medulla oblongata and the foramen magnum. The problem of preoperative diagnosis based on magnetic resonance imaging findings is discussed.

Clinical Advancements in Skull Vibration-Induced Nystagmus (SVIN) over the Last Two Years: A Literature Review.

: Skull vibration-induced nystagmus (SVIN) has become a validated tool for evaluating the vestibular function. The presence of SVIN is a useful indicator of the asymmetry of vestibular function between the two ears. In unilateral vestibular loss, a 100 Hz bone-conducted vibration given to either mastoid immediately causes a primarily horizontal nystagmus.

Volume Reduction Effect of Preoperative Embolization of Only the Feeding Arteries from the External Carotid Artery on Vestibular Schwannomas.

Article Synopsis
- Preoperative embolization for vestibular schwannomas has unclear efficacy, but this study focuses on using only external carotid artery (ECA) feeding arteries to minimize complications associated with other artery embolization.
- The analysis included 15 patients from a larger group of 805 who underwent tumor removal, showing a significant average tumor volume reduction of 15.3% after ECA embolization.
- Results indicate that embolization of ECA feeding arteries is an effective method for reducing tumor size and potentially lowering blood loss during surgery, with measurable effects observed within just a few days post-procedure.
Unexpected Complications Following Accidental Petrosal Vein Damage during Standard Retrosigmoid Surgery for a Large Vestibular Schwannoma: Introspection and Lessons Learned.

We present the case of a patient with a vestibular schwannoma (VS) who developed vascular complications following surgery and discuss the potential mechanisms. Additionally, we systematically searched the literature to identify citations on vascular and brain stem complications following VS surgery. We excluded the articles related to facial and vestibulocochlear nerve-related complications and other complications, such as headache, tinnitus, and ataxia.

Article Synopsis
- - Patients with a history of gamma knife surgery for vestibular schwannoma can develop rare ruptured pseudoaneurysms in the distal anterior inferior cerebellar artery (AICA), and treatment usually involves either surgical trapping or endovascular occlusion.
- - This study highlights the first use of endosaccular coil embolization to treat a ruptured pseudoaneurysm in AICA while preserving the artery, with the patient experiencing recanalization that required additional treatments over two years.
- - The findings suggest that endosaccular coil embolization can be a safe approach for managing radiation-induced pseudoaneurysms, but ongoing monitoring and readiness for further interventions are essential due to the risk of regrowth. *
