Charcot-Bouchard Aneurysm Diagnosed with CTA and MRA.

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.
