Functioning Pituitary Adenoma with Xanthogranulomatous Features: Review of Literature and Case Report.

 We present a patient with a prolactin-secreting adenoma with extensive secondary, noninfectious, xanthogranulomatous changes due to remote intratumoral bleeding and provide a literature review of xanthogranulomas (XGs) of the sellar region with emphasis on prolactinomas with xanthogranulomatous features.  Case report, with PubMed search of cases of sellar XG, focusing on neuroimaging and surgical approach.  A 35-year-old male was found to have a large sellar/suprasellar calcified/cystic mass.

Development of a Novel Canine Model of Ischemic Stroke: Skull Base Approach with Transient Middle Cerebral Artery Occlusion.

Objective: Although canine stroke models have several intrinsic advantages, establishing consistent and reproducible territorial stroke in these models has been challenging because of the abundance of collateral circulation. We have described a skull-base surgical approach that yields reproducible stroke volumes.

Methods: Ten male beagles were studied.

The Tentorial Bridge to Deep Skull Base Exposure: Anatomic Morphometric Study.

Background: Skull base surgeons split the tentorium to expand exposure, minimize brain retraction, and combine the supratentorial and infratentorial compartments for resection of large skull base lesions. The aim of this study was to describe stepwise techniques for splitting the tentorium to access deeply located skull base lesions and morphometrically assess gained exposure.

Methods: Surgical exposures were performed through transsylvian, subtemporal, posterior transpetrosal, and combined posterior supratentorial/infratentorial-transsinus approaches.

Third Ventricular Cerebrospinal Fluid Cysts of Thalamic Origin: Review of Embryologic Origin, Presentation, and Management Strategies with a Case Series.

Objective: Third ventricular cerebrospinal fluid (CSF) cysts of thalamic origin are rare. The objective of this study is to review their possible pathogenesis, clinical presentation, and management strategies with a case series describing management via an endoscopic approach with fenestration using a single burr-hole technique.

Methods: A systematic literature review of reported cases of thalamic cysts was conducted with further meta-analysis of CSF cysts that involve the third ventricle.
