We report a 74-year-old male patient who presented with left hemiplegia and disturbance of consciousness. Computed tomography revealed diffuse subarachnoid hemorrhage, which was prominent in the right Sylvian and basal cisterns. Digital subtraction angiography revealed absence of the C2 segment of the right internal carotid artery (ICA) and a significantly developed circuminfundibular anastomosis. ⋯ It is formed by the superior hypophyseal arteries, prechiasmal arteries, and infundibular arteries bilaterally. Agenesis of the contralateral ICA often leads to development of ICA-ICA anastomoses. In this case, the anastomosis developed due to agenesis of the C2 segment of the right ICA and occlusion of the bilateral VAs.

Carole A. Miller, M. D., was born (May 7, 1939) and raised in Kalamazoo, Michigan. ⋯ Dr. Miller passed away peacefully, on October 28, 2015, after a courageous battle with cancer. Based on her essential programmatic and specialty-related contributions, she is remembered as the 'founding mother' of neurosurgery at the Ohio State University.

Brainstem cavernous malformations account for 15%-18% of all central nervous system cavernomas and are histologically characterized by thin-walled, low-pressure capillaries, classically without intervening brain tissue.1,2 Cavernomas may be sporadic, typically characterized by a single lesion, or inherited. The inherited form is most often autosomal dominant with incomplete penetrance and variable expression. ⋯ We demonstrate the exoscope's unparalleled visualization of the anterolateral brainstem, with nominal condylar drilling. The patient and his parents consented to the procedure and publication.

Individual patient and socioeconomic factors are underexplored prognostic factors for glioblastoma (GBM). Frailty, a measure of physiological vulnerability, and area deprivation, a measure of socioeconomic status, are easily obtained during the preoperative evaluation. These metrics are predictors of outcome and access to treatments for other cancers. Therefore, we sought to determine the association of frailty and neighborhood disadvantage with outcomes of patients with newly diagnosed GBM. ⋯ Increasing frailty and neighborhood disadvantage predict worse outcomes in newly diagnosed patients with GBM undergoing surgery. Patients living in the most-deprived neighborhoods are less likely to receive postoperative chemoradiation. Identification of nontraditional predictors of treatment access and survival will inform mitigation strategies and improve outcomes.
