Pseudoaneurysm formation secondary to spontaneous thrombosis of a massive cerebral arteriovenous malformation.
A case of a large cerebral arteriovenous malformation (AVM) with spontaneous partial thrombosis and intracerebral hematoma is reported. The unusual and unique features of the radionuclide brain scan and cerebral angiogram are described. The characteristic angiographic features of residual tortuosity and dilatation or pseudoaneurysm formation at the bifurcations of the feeding arteries in a partially thrombosed cerebral AVM have not been described previously in the literature.
