The Teaching Point

Holohemispheric DVAs in the pediatric population are rarely diagnosed, although the entity is the most common brain vascular anomaly. Susceptibility weighted angiography (SWAN) is a unique T2 star weighted sequence that definitively characterizes the angioarchitecture and associated features of a DVA for an accurate imaging diagnosis. Acquiring this or similar type of sequences such as SWI may negate the need for catheter based angiography if no atypical features of a DVA are identified.

Abstract
We present a case of an incidentally discovered holohemispheric developmental venous anomaly (DVA) in a 12 year old, conclusively characterized by 3D T2* multi-echo sequence susceptibility weighted angiographic imaging (SWAN). For the evaluation of head trauma, abnormal right intraparenchymal and periventricular vascularity was identified by a non contrast head CT scan. Conventional MRI sequences revealed prominent veins with findings suspicious of a DVA. A definitive diagnosis was made by identifying angiographic features typical for DVA by augmented susceptibility weighted angiographic imaging. Using this sequence the entire hemispheric extent of the anomaly without complicating features was definitively characterized, negating the need for a catheter based angiographic study. A holohemispheric DVA in a child to our knowledge has not been previously described.
