Abstract
The radiologic findings in three patients with dilated transcerebral (medullary) veins detected on routine computed tomography and/or magnetic resonance imaging were reviewed. Sectional imaging showed the dilation of transcerebral veins as well as the dilated superior ophthalmic veins in all patients. It also demonstrated the primary pathology: vein of Galen aneurysmal malformation; dural sinus fistula with varix; and dural arteriovenous fistula. All three patients had both arteriovenous fistula and sinovenous occlusion. We concluded that the dilated transcerebral veins developing secondary to elevation of the cerebral venous pressure, might be the useful radiologic finding of some dural vascular pathologies on sectional imaging.
