Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor predominantly arising in soft tissue. We report a rare case of thoracic spinal EHE with pulmonary metastasis. ⋯ EHE is an exceedingly rare tumor that may present with a wide swath of clinical symptoms. At present, no guidelines or formal treatment recommendations have been established. Surgical debulking has demonstrated efficacy as a front-line treatment, particularly in the setting of compressive neurological dysfunction; data regarding adjuvant chemoradiation are less consistently reported, mandating further study.

Chronic subdural hematomas are a relatively common condition defined as an abnormal collection of blood and its break down products in the subdural space, usually accompanied by a history of preceding mild head trauma. Surgical management remains the mainstay of treatment. The objective of this study was to assess the surgical treatment outcome of patients operated on for chronic subdural hematoma at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia. This comprehensive novel study serves as a benchmark for assessing therapeutic outcomes among patients with chronic subdural hematoma in the context of Ethiopia. ⋯ Chronic subdural hematomas are a relatively common condition characterized by an abnormal collection of blood. Antecedent trauma is the usual risk factor. Complication can happen following surgical intervention; however, patients with chronic subdural hematoma generally have a good prognosis.

The potential advantages of exoscopy have been discussed theoretically for a long time. Such a concept holds significance, especially in the specific setting of the posterior cranial fossa (PCF), characterized by complex anatomy and long and narrow surgical corridors with relatively extreme working angles. ⋯ In conclusion, our study provides a comprehensive evaluation of the advantages and challenges associated with using the exoscope in posterior fossa surgery, setting a precedent as the first to report on a questionnaire-based analysis of exoscope utilization in this specific domain.

Hemifacial spasm (HFS) results from vascular compression at the root exit of the facial nerve. Although the underlying etiology has yet to be identified, it has been suggested that congenital vascular anomalies are involved. We have hypothesized common trunk anomaly of the anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA), may play a role in HFS. However, no previous studies have directly compared the incidence of this anomaly between HFS patients and normal subjects. The present study was designed to address this gap in the literature. ⋯ There was no apparent association between common trunk anomaly and HFS. It is suspected that some vascular anomalies other than a common trunk are involved in HFS.

Flow diversion (FD) for bifurcation aneurysms requires excluding one of the branches from the parent artery, raising concern for ischemic events. Herein, we evaluate thromboembolic events and their relation with covering the origin of the posterior cerebral artery (PCA). ⋯ Thromboembolic events are high in distal basilar and proximal PCA aneurysms, but PCA coverage was not associated with their occurrence. There was no difference in post-procedural disability between patients whose aneurysms were treated excluding one of the PCAs, and those who did not.
