Parapharyngeal and floor‐of‐mouth abscess secondary to tonsillar phlegmon: A rare and unusual cause of Ludwig's angina

Abstract

Abstract We present an unusual case of Ludwig's angina secondary to a left tonsillar phlegmon in a previously fit and well 50‐year‐old woman. This tonsillar phlegmon spread along the peritonsillar/parapharyngeal plane to cause a diffuse cellulitis and collection in the submental, sublingual, and submandibular spaces despite empirical intravenous antibiotic therapy.
