Forgotten disease: an atypical case of Lemierre syndrome presenting as a soft tissue abscess.

Lemierre syndrome (LS) is an acute oropharyngeal infection with secondary septic thrombophlebitis and distant septic embolisation. A 29-year-old woman with sore throat, dyspnoea and left shoulder pain, who was on levofloxacin for 3 days, presented with worsening symptoms. She was tachycardic, tachypneic and hypoxic on presentation. CT of neck and chest revealed multiple loculated abscesses on her left lower neck and shoulder, right peritonsillar abscess, thrombosis of the right external jugular vein and multiple bilateral septic emboli to the lungs. She was started on clindamycin and ampicillin sulbactam for LS. She developed septic shock and required intubation due to respiratory failure. Drainage of the left shoulder abscess grew Fusobacterium nucleatum After 2 weeks of a complicated intensive care unit stay, her haemodynamic status improved and she was transferred to the floor. LS has variable presentations, but regardless of the presentation, it is a potentially fatal disease-requiring prompt diagnosis and management.
