IJV thrombophlebitis: be wary of the occult.

A 43-year-old woman was referred to the Ear, Nose and Throat Department with a 3-day history of left-sided neck pain and swelling associated with fevers and night sweats. She also reported a cough, oral thrush and a dental extraction more than a month previously. A CT scan of the neck with contrast revealed left internal jugular vein (IJV) thrombophlebitis and the patient was initially managed for suspected Lemierre's syndrome.
