    Axial MR images in first patient.
     

    Contrast-enhanced T1-WI of a left frontal deep DVA: portions of the caput along with the superficially draining collector vein are demonstrated.

     
    Area of Interest: unknown; Imaging Technique: Axial MR images in first patient.;

    Observe the hypointense appearance and accentuation of the collector"s vein diameter on the GRE T2*-WI due to the flow characteristics of this anomalous transependymal vein.

Contrast-enhanced T1-WI of a left frontal deep DVA: portions of the caput along with the superficially draining collector vein are demonstrated.
 
Observe the hypointense appearance and accentuation of the collector"s vein diameter on the GRE T2*-WI due to the flow characteristics of this anomalous transependymal vein.
 
Cerebral DSA (venous phase image obtained after injection of the right internal carotid artery) demonstrates the typical radial array of the caput medusae portion of the DVA, which is located in the right posterior frontal region. Note the convergence of the caput"s venules on a dilated, superficially draining collector vein, which ultimately drains into the mid-portion of the superior sagittal sinus.
