Basilar and bilateral carotid dolichoectasia with spontaneous dissection of C2 segment of the internal carotid artery

Abstract

We describe a previously unreported case of cranial arterial dolichoectasia associated with spontaneous dissection of the petrous (C2) segment of the internal carotid artery (ICA) with 2 patent lumena. Dolichoectasia of the cranial arteries and different types of double lumen of ICA are discussed. A review of previously reported cases is included.

A, nonenhanced computerized tomography showing left-sided ganglionic bleeding with penetration of the blood into the left lateral ventricle. B and C, contrast-enhanced computerized tomography (CECT) showing supraclionoid segments of both internal carotid arteries and tortuous and dilated basilar artery. D, CECT, bone window shows symmetrical and normally shaped carotid channels within hyperaerated petrous bones.

Angiogram of the left internal carotid artery, left anterior oblique projection showing double lumen of C2 segment of the internal carotid artery. Note the smooth contours of slightly dilated vascular channels (arrow) and fusiform dilation of the supraclinoid segment of the internal carotid artery (small arrow).
