Craniotomy for perisellar meningiomas: comparison of simple (appropriate for endoscopic approach) versus complex anatomy and surgical outcomes.

OBJECTIVE Microsurgical resection of perisellar meningiomas has remained the gold standard for treatment, with extended endoscopic endonasal surgery emerging as a viable alternative. Historical microsurgical series do not distinguish based on tumor anatomy, but are being used as a comparison against endonasal surgery. In this study, the authors retrospectively reviewed and compared the anatomy of perisellar meningiomas seen at their institution.

Cardiac strangulation following epicardial pacemaker implantation: a rare pediatric complication.

Objectives: The aim of our study was 2-fold: to determine the incidence of cardiac strangulation (CS) and to develop a clinical pathway to aid in the diagnosis and prognosis of CS. In <2 years, 2 cases of CS occurred in our institution, which caused much alarm and led to the study's objectives.

Methods: All patients who underwent implantation of an epicardial pacemaker from January 1992 to March 2012 were included.

Delayed visual loss from optochiasmatic arachnoiditis after resection of craniopharyngioma.

Visual loss following surgery for craniopharyngioma is usually the result of operative injury or tumor recurrence. The authors present the case of a 12-year-old boy who developed progressive visual field constriction 11 years after gross-total resection of a solid and cystic craniopharyngioma. No tumor recurrence was evident on multiple MRI studies, and it was only at surgical exploration that the diagnosis of optochiasmatic arachnoiditis was established.
