Descending necrotizing mediastinitis with Lemierre's syndrome

Abstract

Descending necrotizing mediastinitis is a severe infection of the mediastinum. Lemierre's syndrome manifests as thrombophlebitis in the cervical veins, which is caused by a neck infection. A 50-year-old woman had a fever with a 13-day history of neck pain. CT showed a deep neck abscess with vertebral vein thrombosis and mediastinal abscesses. Multiple small pulmonary nodules were found, suggesting septic pulmonary embolism. Emergency surgery for bilateral cervical and mediastinal drainage was performed, and antibiotics and anticoagulation agent was administered. Edoxaban was required to clear vein thrombosis and pulmonary embolization.
