Giant calcified aneurysm on the posterior cerebral artery in a nine-year-old child

We report the case of a 9-year-old child in whom, after a plain x-ray examination of the skull was performed for a suppurating otitis in the left ear, a calcified lesion was discovered in the left temporal region. Angiographic study showed it to be an aneurysm of the left posterior cerebral artery. The rarity of these lesions is discussed, as well as the successful surgical treatment in this case.
