title: Association between Developmental Venous Anomalies and Cavernous Angiomas: a Retrospective MR Study.
abstract: Developmental venous anomalies (DVA) are large veins usually arranged in a cluster around a collector vein draining directly into the superficial and deep venous systems. Since the introduction of magnetic resonance imaging DVA have been disclosed more frequently. Many studies suggested and then confirmed the association between cavernous angioma and developmental venous anomaly, described for the first time by Roberson in 1974. The aim of our study was a retrospective assessment of the case series at our institution, namely to determine the frequency of the association between developmental venous anomaly and cavernous and analyse the relation between the two lesions.
