Lemierre syndrome: usefulness of CT in detection of extensive occult thrombophlebitis.

We report a case of Lemierre syndrome with extensive suppurative thrombophlebitis involving concomitantly the internal jugular, facial and anterior jugular veins. This case illustrates two unusual clinical and imaging features: the lack of characteristic neck symptoms at admission and a negative initial neck US exam. The value of postcontrast CT of the neck and chest for diagnosis of this potentially life-threatening syndrome is illustrated.
