Review Case Reports
Small cell glioblastoma of the sella turcica region: a case report and review of the literature.
Glioblastomas in the sellar region are very rare; in most cases, the tumor originates from the optic nerve or optic chiasm. Only 4 cases of sellar glioblastoma with a nonoptic origin have been reported. We present such a case with detailed clinical, imaging, and histopathologic information. We also review similar published cases. ⋯ This is the first report of a small cell glioblastoma in the sella turcica region. Glioblastomas in the sellar region with no clear evidence of an optic origin should be viewed as an independent disease entity. The typical characteristics of this tumor indicate it should be considered a rare subtype of glioblastoma. Further accumulation of experience is needed to better differentiate these cases and to offer optimal treatment.

Review Case Reports
Pituitary Ependymoma: A Case Report and Review of the Literature.
Pituitary ependymoma is exceptionally rare. Its etiology, clinical presentation, radiologic feature, and treatment strategy are still a matter of debate. Only 7 human cases with limited data were reported in the English literature, and now we described another case of pituitary ependymoma. We also systematically reviewed previously reported cases and described its potential etiology, clinical presentation, radiologic features, pathology, immunohistochemical analysis, and ultrastructural examinations. ⋯ To our knowledge, only 7 patients with ependymoma in the sellar region have been described in the English literature. We reported 1 more case of pituitary ependymoma and discussed the potential etiology, clinical presentation, radiologic features, pathology, immunohistochemical analysis, ultrastructural examinations, treatment, surgery, radiotherapy, chemotherapy, and prognosis of pituitary ependymoma. The case report may serve as a helpful reference for clinicians and radiologists.

Review Case Reports
Intracranial Erdheim-Chester Disease Mimicking Parafalcine Meningioma: Report of Two Cases and Review of the Literature.
Erdheim-Chester disease (ECD) is a rare, non-Langerhans cell histiocytosis that typically occurs in middle-aged patients. It is usually characterized by multifocal osteosclerotic lesions of the long-bones, however many cases have extraskeletal involvement. Central nervous system (CNS) involvement is common, but isolated CNS involvement at presentation has rarely been reported. ⋯ ECD is a rare disease, with isolated CNS involvement reported only a few times in the literature. The significance of this presentation requires additional study and long-term follow up.

Multicenter Study
Microsurgical treatment of ruptured intracranial aneurysms in sub-Saharan Africa: a series of 102 consecutive cases treated in Senegal.
In sub-Saharan Africa, the management of ruptured intracranial aneurysms (RIAs) is difficult for many reasons. In this retrospective, 3-year study, the authors will demonstrate the particularities of the management of RIAs in Senegal. ⋯ This study demonstrates encouraging results if one refers to the global patient postoperative outcomes. However, the large number of patients not undergoing treatment also requires us to improve preoperative management conditions.

Ventriculoperitoneal (VP) shunting is a well-established therapy for hydrocephalus. However, complications are frequent. The incidence of idiopathic normal pressure hydrocephalus (NPH) increases with the aging of the population. We evaluated the functional status of patients and the classification of complications associated with VP shunt procedures in our center. ⋯ Although shunt surgery has a high general rate of complications, this rate is significantly lower for patients with NPH. The decision for shunting in patients with NPH should consider the low complication rate specific for the group of patients with NPH.
