Summary
CT was performed on ten cases of dural intracranial arteriovenous fistulas. There were 3 fistulas of the transverse sinus draining directly into the homolateral jugular vein; 2 fistulas of the sinus with distal occlusion of the sinus and back flow into the cortical veins (one was on the transverse sinus, the other on the sagittal sinus); 2 fistulas of the middle fossa; 3 fistulas with direct venous drainage into the cortical veins, one of these forming a tumor process in the posterior fossa. Osseous abnormalities were seen in only one case. Cerebral CT abnormalities, such as patchy or vermicular enhancement, were seen in all the cases with fistulas draining into the cerebral veins. Cerebral CT was normal in cases of fistulas of the sinus without back flow into the cerebral veins.
