A case of petrous carotid artery pseudoaneurysm presenting with epistaxis after radiotherapy in a patient with nasopharyngeal cancer / 대한내과학회지

ABSTRACT

Rupture of an internal carotid artery pseudoaneurysm is a rare but lethal complication in patients with nasopharyngeal cancer. Here, we report a case of severe nasal bleeding from a left petrous internal carotid artery aneurysm after chemoradiotherapy in a patient with nasopharyngeal cancer. A 76-year-old man who was being treated with concurrent chemoradiotherapy and who had achieved a complete response for 14 months developed massive epistaxis . A postnasal space computed tomography scan showed an enhanced nodular lesion at the left petrous internal carotid artery, and angiography revealed a pseudoaneurysm measuring 11.5x9.1 mm in the left internal carotid artery. Bleeding was well controlled with endovascular occlusion using a coil. The patient showed no recurrence of bleeding during follow-up.
