Abstract

A case of a non-traumatic giant aneurysm of the middle meningeal artery is presented in a 59-year-old patient with a history of liver transplantation, liver cirrhosis and hepatocarcinoma, chronic renal disease, hypertension and chronic bronchitis who presented with tonic-clonic seizures. CT and MRI showed a lesion suggestive of metastasis without ruling out a glial type tumor. He was operated through a left FT craniotomy. During the surgery there was an arterial hemorrhage. The histological sample oriented toward an aneurysmal origin that was confirmed with ARM and angiography. A second intervention allowed the removal of a giant middle meningeal aneurysm partially thrombosed. Aneurysms of the middle meningeal artery are rare and generally present a traumatic history. No case of giant aneurysm has been found in the medical literature.

Keywords: Aneurisma gigante; Arteria meníngea media; Gyant aneurysm; Middle meningeal artery.
