Abstract: Giant cavernous segment of carotid artery aneurysms are rare pathologic entities that are typically benign and are considered less life-threatening due to the low risk of rupture of bleeding. They present with clinical features usually due to mass effects on adjacent neural structures, mainly the III, IV, V, and VI cranial nerves. Clinical symptoms depend on aneurysm's location. Differential diagnosis includes pituitary adenoma, meningioma, Craniopharyngioma, glioma, and ven granuloma. Here, the authors report a case of a 62-year-old female patient with a giant partial thrombosed aneurysm of the internal cavernous segment of carotid artery mimicking a meningioma of the lesser wing of the sphenoid bone who presented for visual defect, and raised intracranial pressure. The authors will proceed with a literature review investigating this entity as well its ability of mimicking meningioma.
