Absence of Deep and Basal Veins Is Common and Clinically Relevant in Sturge-Weber Syndrome.

ABSTRACT:

Background

Common intracranial vascular abnormalities in Sturge-Weber syndrome (SWS) include leptomeningeal venous malformations (LVMs) and enlarged deep veins. A few small studies have reported absent deep veins in some patients. We used susceptibility-weighted imaging (SWI), a magnetic resonance imaging (MRI) sequence sensitive to detecting small veins, to evaluate deep cerebral veins and the basal vein of Rosenthal (BVR) and assess the radiological correlates and clinical impact of their absence.

Methods

Fifty young subjects, including 30 patients with unilateral SWS and 20 healthy controls, underwent 3T brain MRI prospectively. The presence or absence of the internal cerebral vein (ICV), its two main tributaries, and the BVR were evaluated on SWI in all 50 subjects and c
