Imaging and Intervention in Internal Carotid Artery Pseudoaneurysm Secondary to Retropharyngeal Abscess

Vascular complications secondary to retropharyngeal abscess are rarely encountered in the post antibiotic era and include compression of internal carotid artery (ICA), infective arteritis and pseudoaneurysm formation. Post infectious ICA pseudoaneurysm formation is reported predominantly in the paediatric age group and rare in adults. We report a case of retropharyngeal abscess complicated by ICA pseudoaneurysm in an adult successfully managed by endovascular approach.
