Name of journal: Pediatric neurologyAbstract: BACKGROUND: Intracranial vascular abnormalities in Sturge-Weber syndrome, including leptomeningeal angiomatosis, anomalous cortical venous structures, and transmedullary developmental venous anomalies, are well recognized. Prominent vascular flow voids on T2-weighted magnetic resonance imaging (MRI) are occasionally identified in patients with Sturge-Weber syndrome, raising concern of arteriovenous malformations, a congenital high-flow vascular malformation with a risk of bleeding.CONCLUSIONS: This series highlights that developmental venous anomalies may appear in individuals with Sturge-Weber syndrome as unusually large and seemingly high-flow lesions on MRI. Noninvasive imaging with magnetic resonance angiography and magnetic resonance venography can be used in the management of such patients for further characterization of these vascular structures.

BACKGROUND: Intracranial vascular abnormalities in Sturge-Weber syndrome, including leptomeningeal angiomatosis, anomalous cortical venous structures, and transmedullary developmental venous anomalies, are well recognized. Prominent vascular flow voids on T2-weighted magnetic resonance imaging (MRI) are occasionally identified in patients with Sturge-Weber syndrome, raising concern of arteriovenous malformations, a congenital high-flow vascular malformation with a risk of bleeding.

CONCLUSIONS: This series highlights that developmental venous anomalies may appear in individuals with Sturge-Weber syndrome as unusually large and seemingly high-flow lesions on MRI.

METHODS: We report four patients with prominent flow voids on conventional MRI that suggested high-flow lesions.

RESULTS: Diagnostic evaluation was performed with cerebral angiography in one patient and with a combination of magnetic resonance angiography and magnetic resonance venography in three patients. In all four patients, the conventional MRI-identified lesions represented prominent developmental venous anomalies and not arteriovenous malformations.
