Review Case Reports
Spinal arachnoid cyst associated with arachnoiditis following subarachnoid haemorrhage in adult patients: A case report and literature review.
Arachnoiditis is an inflammatory process resulting with the fibrosis of arachnoid mater. It can vary in severity from mild thickenings to catastrophic adhesions that ruins subarachnoid space. As a result, arachnoid cysts can be formed. Arachnoid cyst induced by symptomatic spinal arachnoiditis is a rare complication of subarachnoid haemorrhages. In this article, we aimed to present a case of spinal arachnoid cyst formation following subarachnoid haemorrhage and examine similar cases in the literature. ⋯ Subarachnoiditis and associated arachnoid cyst can cause severe morbidity. This rare situation (which especially occurs following subarachnoid haemorrhage of posterior fossa) should be known and physicians should keep in mind that it requires urgent surgical procedure.

Review Case Reports
Primary sellar melanocytic tumor mimicking hemorrhagic pituitary macroadenoma: Case report and literature review.
Primary melanocytic tumors of the central nervous system (CNS) are rare lesions, but primary sellar tumors are rarer. Only 10 cases have been reported, and they are often misdiagnosed as pituitary macroadenoma. We report the case of a 54-year-old Chinese man who developed progressive bitemporal hemianopsia and visual loss. ⋯ Once this type of lesion is suspected, the transfrontal approach may achieve preferable exposure and resection. Complete surgical resection may be sufficient for relatively benign lesions; otherwise, stereotactic fractionated radiotherapy is indicated. More cases should be reported to improve the treatment strategy.

Facial nerve schwannomas (FNS) are rare tumors, and their appropriate management remains the subject of considerable debate. This report details the results of a series of patients with FNS treated with stereotactic radiosurgery (SRS) at the University of Virginia. ⋯ SRS appears to offer a reasonable rate of facial nerve preservation and tumor control for patients with small-to-medium-sized FNS. Considering the published outcomes achieved with resection, RS may be the preferred first-line treatment for these tumors.
