Abstract
We report two cases in which MR imaging was used to diagnose multiple cereb ral aneurysms caused by cardiac myxoma. In one case, the diagnosis was conf irmed with cerebral angiography. Myxomatous aneurysms characteristically ap peared on TI-weighted images as contrast-enhancing focal fusiform dilatatio ns of distal segments of the cerebral arteries. On T2-weighted images, thes e myxomatous aneurysms appeared as low signal intensity flow voids, sometim es associated with cerebral infarctions.
