title: Nontraumatic and postirradiated intracavernous carotid hemorrhage: an unusual case of epistaxis and review of the literature.
abstract: Intracavernous carotid hemorrhage is a rare cause of epistaxis. We present a case of epistaxis caused by postradiotherapy and nontraumatic cavernous internal carotid artery (ICA) hemorrhage. An 80-year-old man was admitted to our hospital with a one week history of recurrent left-sided epistaxis and a past history of radiotherapy after radical maxillectomy. Emergent angiography revealed a leak in the cavernous segment of the ICA and subsequent detachable balloon occlusion embolization of the left internal carotid artery was performed without sequelae. We conclude that carotid artery hemorrhage must be considered in the differential diagnosis of profuse and recurrent epistaxis, especially for patients after craniofacial radiotherapy. ICA embolization is the definitive treatment provided cross circulation is adequate.
