Aneurysm of Petrous and Cavernous Parts of the Internal Carotid Artery: A Case Report.

Abstract

İnternal carotid artery (ICA)aneurysmsare rare but they can cause high morbidity and mortality. Although these aneurysms are usually asymptomatic, they can reach huge sizes and compress the surrounding neurovascular structures. Patients typically present with neurologic symptoms due to cranial nerve compression. If they rupture, they can lead to massive epistaxis and autorage. In physical examination, pulsatile mass in the middle ear or nasal cavity can be seen. If there is a clinical suspicion of an ICA aneurysms, diagnostic radiological imaging should be performed before the surgical procedure or biopsy. Cerebral digital subtraction angiography (DSA) should be performed for definitive diagnosis. After diagnosis, appropriate endovascular or open intervention should be performed. In this case report, we present a 48-year-old female patient with severe epistaxis complaint due to an ICA aneurysm. This report aims to present this case and review the current literature.
