Abstract

Pituitary adenomas commonly present with visual or hormonal disturbances, while vascular complications are rare and usually associated with pituitary apoplexy. We describe a 70-year-old man who presented with acute right upper limb weakness and dysarthria consistent with a transient ischemic attack. Magnetic resonance imaging (MRI) revealed a giant pituitary macroadenoma with bilateral parasellar extension, more pronounced on the right side, with encasement of the right cavernous carotid artery, giving it the appearance of the “snowman sign”.
