BAPTISTA, Ana Vieira et al. Stroke of a rare etiology with need of urgent surgery: case report. Angiol Cir Vasc [online]. 2012, vol.8, n.1, pp.12-16. ISSN 1646-706X.

19 years old patient with fever for 8 days associated with sudden aphasia, left hemiparesis and abnormal behavior. Increased acute phase proteins in the analytical study. Head CT scan and MRI revealed a right temporo-parietal ischemic lesion. An echocardiogram excluded endocarditis. Ultrasound and CT angiography scanning of the extracranial cerebral circulation showed a vegetative formation, mobile with the heartbeat, in the right common carotid artery. Submitted, urgently, to carotid surgery. Intraoperatively, a slightly adherent thrombus to the common carotid artery was found and in the dependence of an underlying injury to the intima. The thrombus was ressected and a primary arteriorrhaphy performed. It is pointed out a vasculitis secondary to HSV1 (active infection) or to Rickettsia conorii infection as the most likely etiology of the clinic.
