B, Contrast-enhanced axial CT scan shows intense enhancement of the lesion. C, Contrast-enhanced axial CT scan shows multiple subependymal veins joining to form collector veins unifying into a tortuous channel in the region of the right sylvian fissure and continuing to the region of the anterior temporal enhancing extraaxial lesion. Abnormal enhancing vessels are also seen in the left frontal region.
FIG 2. A, -B, Right and left internal carotid artery angiograms show a normal arterial phase.
FIG 3. A, -B, Anteroposterior view of early and late venous phases of the right internal carotid artery angiograms shows the presence of 2 varices and the venous angioma.
FIG 4. Lateral view of the venous phase of the right internal carotid artery angiogram shows a classic “Medusa head” appearance with a draining vein varix in the region of the right superficial middle cerebral vein.
FIG 5. Lateral view of the venous phase of the left internal carotid artery angiogram shows a classic “Medusa head” appearance draining into the superior sagittal sinus.
