We review our 8-year experience with gamma knife radiosurgery (GKRS) for the treatment of patients with benign cavernous sinus tumors and present a quantitative analysis of factors relevant to treatment outcomes. ⋯ GKRS is a safe and effective treatment for selected patients with benign cavernous sinus tumors and is an important adjunct for treating postoperative tumor residual and/or recurrent tumor. Continued analysis of treated patients over an extended time is needed to evaluate long-term disease control and potential late GKRS complications.

A neuroforensic analysis of the wounds of President John F. Kennedy: Part 2--A study of the available evidence, eyewitness correlations, analysis, and conclusions.
A substantial body of literature exists surrounding the assassination and subsequent pathological examination of President John F. Kennedy. In the first part of this series, we provided a previously undocumented eyewitness account by a neurosurgeon of what transpired in Trauma Room 1 of Parkland Memorial Hospital on November 22, 1963. ⋯ The autopsy report, ballistics data, official reviews of the autopsy data, and Dr. Grossman's observations are correlated in an effort to provide a neuroforensic analysis of the nature of the wounds that President Kennedy sustained. The final article of the series will relate the wounds to the timing of the shots and the location of the President as his limousine traversed Dealey Plaza and will discuss the sites from which the bullets could have been fired.

We hypothesized that coexisting extranidal arterial aneurysms (EAs) would be associated with an increased risk of incident intracranial hemorrhage (ICH) from brain arteriovenous malformation (BAVM) rupture. ⋯ Clinical presentation with ICH was associated with EA aneurysms, but the association was due to aneurysmal rather than BAVM rupture, suggesting that EAs and the BAVM ICH risks may be considered as separate entities in future studies.

To describe the exposure obtained through six approaches to the perimesencephalic cisterns with an emphasis on exposure of the posterior cerebral artery and its branches. ⋯ Surgical approaches to lesions of the perimesencephalic cisterns must be tailored to the site of the pathological findings. The most challenging area to expose is the upper half of the ambient cistern, particularly the P2p segment of the posterior cerebral artery.
