Degree of Vascular Encasement in Sphenoid Wing Meningiomas Predicts Postoperative Ischemic Complications.

Background: Sphenoid wing meningiomas (SWMs) can encase arteries of the circle of Willis, increasing their susceptibility to intraoperative vascular injury and severe ischemic complications.

Objective: To demonstrate the effect of circumferential vascular encasement in SWM on postoperative ischemia.

Methods: A retrospective review of 75 patients surgically treated for SWM from 2009 to 2015 was undertaken to determine the degree of circumferential vascular encasement (0°-360°) as assessed by preoperative magnetic resonance imaging (MRI).

Pesticide-associated pemphigus vulgaris.

We present a 40-year-old man with occupation-induced pemphigus vulgaris (PV). He developed PV within days of a one-time heavy exposure to fumes of burning glyphosate, a broad-spectrum nonselective pesticide. This exposure suggests acute cutaneous contact as a stimulus in the development of his pemphigus.
