Review Case Reports
Pure Intrasellar Meningioma Mimicking Pituitary Macroadenoma: MR Imaging and Review of the Literature.
Intrasellar meningioma originating from the sellar floor is extremely rare and is often indistinguishable from pituitary macroadenoma, both clinically and radiologically. Here, we report a case involving a 68-year-old patient with intrasellar meningioma possibly originating from the sellar floor and present a brief review of all previous cases reported in the English literature.

Review Case Reports
Role of denosumab in endoscopic endonasal treatment for juvenile clival giant cell tumor: a case report.
Giant cell tumors (GCTs) are histologically benign bone neoplasms with a locally aggressive nature that primarily occur in the epiphyses of the long bones. A small proportion of these tumors, however, occur in the pelvis, spine, or skull bones. Among these, GCTs of the skull base cannot be completely resected and require adjuvant therapy. We report a juvenile case of clival GCT that was successfully treated by endoscopic endonasal transsphenoidal surgery and subsequent adjuvant therapy with denosumab, a monoclonal antibody to receptor activator of nuclear factor-κB ligand. ⋯ This is the first report to describe beneficial effects of denosumab in the treatment of GCT of the skull base.

Review Case Reports
Nerve transfer for facial paralysis under IV sedation and local analgesia for the high surgical risk elderly patient.
This case report describes an 86-year-old woman with complete peripheral right-sided facial paralysis resulting from resection of a cervical lipoma 14 months before surgery. ⋯ To our knowledge, nerve transfers under light sedation and local anesthesia have not been described in the literature and may be useful in elderly patients with significant comorbidities.

Review Case Reports
Syringomyelia caused by traumatic intracranial hypotension: a case report and literature review.
Syringomyelia due to intracranial hypotension is rarely described. As a consequence, intracranial hypotension is less recognized as a potential cause of syringomyelia or mistaken with Chiari type 1 malformation. The pathogeny is poorly understood, and we lack diagnostic and therapeutic strategies for this particular setting. ⋯ Syringomyelia can be a consequence of long-term progression of intracranial hypotension, which must be differentiated from Chiari type 1 malformation. In our case, resolution was achieved by detecting and closing the CSF leak causing the intracranial hypotension. Reports of similar cases are necessary to understand the origin of CSF leak in traumatic intracranial hypotension and assess the best therapeutic strategy.

Endovascular treatment of posterior cerebral artery aneurysms is challenging because of the particular features of posterior circulation vessels. We performed a systematic review of the literature, to assess safety and efficacy associated to their endovascular treatment. ⋯ Endovascular treatment of posterior cerebral artery aneurysms is associated with increased degree of occlusion and low recurrence rate. However, a parent artery occlusion implies complications, even although most of them are minor events such as hemianopsia.
