This study evaluated the characteristics of vestibular schwannomas (VS) in young patients, including clinical features, treatment, prognosis, and histopathologic characteristics. ⋯ Tumor size is an important factor affecting the prognosis of VS in young patients. For large VS, surgical treatment should be the first choice, rather than wait-and-scan. VS in young patients shows high tumor proliferation and a tendency to relapse. The cellular schwannoma subtype requires special attention; an accurate histopathologic diagnosis is necessary for young patients with VS, and a closer follow-up strategy should be adopted for cellular VS.

Spinal subdural hematoma (SSH) is a rare and infrequently reported complication of hemilaminectomy, laminectomy, and other spinal decompression surgeries. In this review, we aim to analyze the available literature for reported cases of SSH to better identify risk factors and presenting symptoms, as well as highlight the importance in prompt investigation and management of SSH to prevent long-term morbidity and chronic neurologic deficit. ⋯ SSH is a rare, emergency condition with neurologic deficit that can present as recurrent back pain and acute cauda equina postoperatively following hemilaminectomy and laminectomy procedures. Vigilance, early investigation, and surgical evacuation is important in preventing short- and long-term morbidity. Further collation of data and analysis is required to better identify patients at high risk for developing SSH postoperatively.

To analyze radiologic characteristics, treatment strategy, and treatment outcomes of posterior fossa giant solid hemangioblastomas (GSHBs; ≥4 cm in maximum diameter). ⋯ GSHBs are surgically challenging. The current study shows that favorable outcome can be achieved for GSHBs in the cerebellar hemispheres and vermis. For those involving the brainstem, planned near-total resection or subtotal resection in a piecemeal fashion can be attempted if en bloc resection is judged to be infeasible, and further intervention can be considered as needed.
