title: Fusiform aneurysmal dilatation of pericallosal artery. A sign of lipoma of corpus callosum.
abstract: Two cases of lipoma of the corpus callosum with aneurysmal dilatation of the pericallosal artery are reported. This appears to be a reliable sign of lipoma of the corpus callosum. Our cases and the literature reveal that 19 of 22 cases with illustrations of carotid angiography have demonstrated such an aneurysmal dilatation.
