Nontraumatic intracavernous carotid aneurysm presenting with epistaxis.

A patient with an intracavernous carotid aneurysm usually presents with symptoms and signs of a space occupying lesion, producing one of a variety of types of cavernous sinus syndromes (Jefferson, 1938). Epistaxis is an unusual feature in these patients and when present is nearly always associated with a traumatic aneurysm (Mahmoud, 1979). There are only two reported cases of non-traumatic intracavernous carotid aneurysms presenting with epistaxis and diagnosed during the lifetime of the patient (Troupp, 1962; Labayle and Legent, 1964). The authors present a third such case. The importance of considering aneurysms in the differential diagnosis of epistaxis is emphasised. The radiological investigations and management of these patients is discussed.
