Iatrogenic cortical aneurysm post-craniotomy.
Taking into account the number of craniotomies performed every day around the world, iatrogenic aneurysm post-craniotomy is extremely rare with only anecdotal cases reported in literature. We report an iatrogenic aneurysm affecting a cortical vessel which probably developed during dural closure of a conventional craniotomy. The aneurysm was discovered 6 months after surgery on a routine control angiography. The patient was successfully treated by trapping the parent vessel and excising the aneurysm. Histopathological findings were compatible with a true type of traumatic aneurysm. The possibility of this rare condition occurring highlights the risk of arterial injury during craniotomy.
