title: Hypopituitarism resulting from an intrasellar carotid aneurysm.
abstract: We report a 74 year old lady who presented with an exceedingly rare combination of an internal carotid artery aneurysm which was almost entirely intrasellar and associated with hypopituitarism but no neurological deficits. Such a lesion could be misdiagnosed as a pituitary tumour with serious consequences, if surgery is attempted without prior carotid angiography.
