Fig 1 a-b : Comparison of GE T2*-weighted and contrast-enhanced T1-weighted images of a left frontal deep DVA (pt 1). Portions of the caput are are best seen on the contrast- enhanced T1-WI.Observe the hypointense appearance and accentuation of the collector's vein diameter on the GE T2*-WI, due to the flow characteristics of this anomalous transependymal vein. The collector vein drains superficially into an enlarged left frontal cortical vein.

Fig 2 a-c : Coronal contrast-enhancd T1-weighted images (from posterior to anterior), elegantly demonstrate the ultimate superficial drainage of the deep DVA into the anterior portion of the superior sagittal sinus via an enlarged cortical vein. (Note the multiple, bilateral hemispheric, enhancing lesions which are probably secondary in nature).

Fig 3 a-b : Cerebral DSA, venous phase images obtained after injection of the right internal carotid artery. Succesive images demonstrate the typical radial array of the caput medusae portion of the DVA (located in the right posterior frontal region) and the convergence of the caput on a dilated, superficially draining collector vein, which ultimately drains into the mid-portion of the superior sagittal sinus.
