  • Title: Venous aneurysm development associated with a dural arteriovenous fistula of the anterior cranial fossa with devastating hemorrhage--case report.
    Author: Hashiguchi A, Mimata C, Ichimura H, Morioka M, Kuratsu J.
    Journal: Neurol Med Chir (Tokyo); 2007 Feb; 47(2):70-3. PubMed ID: 17317944.
    Abstract:
    A 67-year-old man presented with devastating intracranial hemorrhage (ICH) from an anterior cranial fossa dural arteriovenous fistula (DAVF). Four years earlier, digital subtraction angiography had disclosed a DAVF at the right anterior cranial fossa fed mainly by the ethmoidal branches of the bilateral sphenopalatine arteries and slightly by the ethmoidal arteries of the bilateral ophthalmic arteries, and drained primarily by the sphenoparietal and cavernous sinuses via two dilated cortical veins and slightly by the superior sagittal sinus via a frontal ascending vein. Three-dimensional computed tomography angiography revealed the development of a venous aneurysm on the main draining vein over a 4-year period, but no other changes. Venous aneurysm development may be part of the natural history of DAVF with cortical venous drainage and may contribute to the occurrence of ICH.
