Vascular complication of neck space infection: case report and literature review.

Antibiotic therapy has changed the face of medicine radically, and physicians no longer have the empirical knowledge of bacterial infections that they once had. Consequently, the diagnosis and management of complicated infections presents a significant challenge to today's otolaryngologists. We present a rare complication, even before the advent of antibiotics, of a head and neck infection: a carotid artery pseudoaneurysm resulting from peritonsillar abscess. The diagnosis and management of this problem is discussed and the pertinent literature reviewed.
