Abstract
Septic pulmonary embolism （SPE） is a rare but serious infectious disorder. Clinically, SPE is associated with easily documented infections, such as bacterial endocarditis, septic thrombophlebitis, and infected central venous catheters. Odontogenic infection is a rare cause of SPE. We report on a 59-year-old man who visited our hospital because of right mandibular swelling and dysphagia. The diagnosis was a perimandibular abscess due to inflammation of a tooth extraction wound. Since the patient lost consciousness after admission to our hospital, urgent intratracheal intubation was performed. Chest computed tomography showed multiple nodular shadows with features characteristics of SPE. Blood examination revealed diabetes mellitus and disseminated intravascular coagulation （DIC）. Blood culture failed to detect causative bacteria. Antimicrobial agents combined with drainage of the perimandibular abscess were a successful treatment. Odontogenic infection is considered a possible source of SPE.
