Abstract
BACKGROUND Intracranial dissecting aneurysms are relatively rare. We presen t a rare case of a dissecting aneurysm originating from the anterior choroi dal artery; this is the first reported case. CASE DESCRIPTION A 42-year-old man suffered sudden onset of right hemipares is and dysarthria. Computed tomography on admission revealed a small low de nsity area in the posterior limb of the internal capsule. MR imaging reveal ed aneurysmal dilatation of the anterior choroidal artery, and angiography revealed aneurysmal dilatation and stasis of dye in the venous phase at the anterior choroidal artery, which resolved in the chronic stage. CONCLUSION We describe a rare case of a dissecting aneurysm of the anterior choroidal artery. The radiological findings were characteristic of dissect ing aneurysms in spite of the rare location.
