Abstract

Pseudoaneurysm of the internal carotid artery (ICA) is a rare but life-threatening vascular complication that may occur in the setting of severe otogenic infections. We report the case of a 16-year-old patient presenting with otorrhea in the context of acute otomastoiditis. Imaging revealed a pseudoaneurysm of the petrous segment of the internal carotid artery associated with adjacent inflammatory changes of the middle ear and mastoid air cells. This case emphasizes the critical role of early CT angiography and MRI in identifying vascular complications of ear infections and preventing fatal hemorrhagic events.
