Charcot-Bouchard Aneurysm Diagnosed with CTA and MRA

Abstract

Hemorrhage in the basal ganglia resulting to lenticulostriate artery aneurysm rupture is extremely rare. This distal micro-aneurysm of the perforating lenticulostriate arteries is called Charcot-Bouchard aneurysm. We wish to report a case of an hematoma in the basal ganglia due to a Charcot-Bouchard aneurysm demonstrated by Computed Tomography Angiograpy (CTA) and Magnetic Resonance Angiography (MRA) and confirmed by selective catheter angiography.

Teaching point: Charcot-Bouchard aneurysm is a very rare distal micro-aneurysm of the perforating lenticulostriate arteries. Young patients who experience basal ganglia hemorrhage should have contrast-enhanced CT, especially if they don't have arterial hypertension and if subarachnoid hemorrhage is associated.

Keywords: Charcot-Bouchard aneurysm; basal ganglia hematoma.

(a) Plain CT: Hemorrhage in the left basal ganglia (Arrow) (b) Plain CT at a lower level: Notice subarachnoid hemorrhage in the cistern of the middle cerebral artery and the insula (arrowheads) (c) CTA: Notice fusiform aneurysm (arrow) on a distal lenticulostriate artery. (d) Magnified view of CTA showing the aneurysm in continuity ith the lenticulostriate artery (arrow).
