Intracranial Bruit Over an Ependymoblastoma. Report of a Case

Abstract

A case, aged 6, of intracranial tumor with a bruit over bilateral eyeballs and temporal regions was presented with an accompanying phonocardiogram. The bruit decreased when the ipsilateral carotid artery was compressed. Operation disclosed an ependymoblastoma in the left superficial central area. The bruit disappeared after subtotal excision (200 g). In this case, the intracranial bruit was caused by highly vascular character with three afferent vessels, the superficial location and multiple arteriovenous communication with red veins. The literature pertinent to intracranial bruits, their significance and pathophysiology, was briefly reviewed, and the importance of cranial auscultation was stressed. © 1976, The Japanese Society of Child Neurology.
