title: Delayed massive epistaxis due to traumatic intracavernous carotid artery pseudoaneurysm.
abstract: Recurrent epistaxes after head injury may rarely be due to a traumatic intracavernous carotid artery pseudoaneurysm. The head injury is usually associated with fracture of the skull base and the epistaxes are severe with the first episode generally occurring one to three months after the initial trauma. We present a case which illustrates the role of high resolution computed tomography (CT) scanning and also magnetic resonance angiography (MRA) in achieving the diagnosis.
