There is a dearth of information on operated cases of spinal tumors in patients in sub-Saharan Africa. The objective of this study was to evaluate the histologic pattern, anatomic distribution, and extent and outcome of surgery of Nigerian patients with spinal tumors. ⋯ Metastasis was the most common histologic type of spinal tumor in this study, and the most common location was extradural. The outcome was satisfactory in most cases with neurologic function remaining the same or improving after surgery in most patients.

To quantitatively study the degree of posterior fossa crowdedness (PFC) in patients with hemifacial spasm (HFS) and to further investigate whether overcrowding in posterior fossa affects the efficacy and safety of microvascular decompression. ⋯ Patients with HFS had more PFC. PFC potentially leads to cranial nerve and vascular structure crowding, which may increase HFS risk. PFC was significantly associated with poor short-term outcomes and greater incidence of early complications but not long-term outcomes and complications.

The goal of this study was to discuss the surgical indications, surgical approaches, and prognostic factors of cerebellar cavernous malformation (CM). ⋯ Patients with cerebellar CMs usually achieve favorable outcomes via surgery. Cerebellar peduncle CMs cause significantly more neurologic deficits than other locations. A reasonable surgical approach and meticulous manipulation are necessary to prevent impairment of neurologic function.

Decompressive craniectomy (DC) requires later cranioplasty (CP) in survivors. However, if additional ventriculoperitoneal shunt (VPS) placement due to shunt-dependent hydrocephalus is necessary, the optimal timing of both procedures still remains controversial. We therefore analyzed our computerized database concerning the optimal timing of CP and VPS regarding postoperative complications. ⋯ We provide detailed data on surgical timing and complications for cranioplasty and ventriculoperitoneal shunt placement after DC. The present data suggest that patients who undergo staged CP and VPS procedures might benefit from a lower complication rate. This might influence future surgical decision making regarding optimal timing of CP and VPS placement.

Intracranial atypical meningiomas have a greater rate of recurrence than benign meningiomas. Scant literature, however, is available regarding the treatment and prognosis of these tumors after recurrence. The objective of this study was to analyze the treatment outcomes and prognostic factors of atypical meningiomas after recurrence of disease. ⋯ Recurrent atypical meningiomas are intractable tumors with a high rate of recurrence and death. Total resection of the tumors under relatively safe conditions remains the most suitable treatment strategy.
