Ludwig's angina, anterior neck abscess and cavernous venous thrombosis following third molar extraction

Ludwig's angina (LA) is a rapidly progressing cellulitis that develops after oral infections or molar extractions, typically causing fever and chills and rarely progressing to trismus and cyanosis. It is associated with risk factors including diabetes mellitus, heavy alcohol use, oral malignancy, poor dentition or an immunocompromised state. This case report reviews a previously healthy patient with no appreciable risk factors presenting with LA following a third molar extraction, complicated by extensive anterior deep neck space abscesses, cavernous venous thrombosis and Lemierre's Syndrome. Our case demonstrates the importance of early intervention when suspecting LA to prevent life-threatening complications and death.
