[Imaging of Lemierre in children and young adults].

PURPOSE: The aim of this study is to describe the role of imaging in the medical care of Lemierre Syndrome and to describe its US, CT and MRI features.

PATIENTS AND METHODS: Files of patients diagnosed with Lemierre Syndrome between 2005 and 2011 at CHUV hospital have been analysed retrospectively to define its imaging semiology.

RESULTS: IJV thrombosis was demonstrated by US, CT and MRI. Septic pulmonary emboli were detected by CT. Complications of the Lemierre Syndrome were depicted by MR and CT.

CONCLUSION: US, CT or MR evidence of IJV thrombosis and chest CT suggestive of septic emboli, should lead the physician to diagnose Lemierre Syndrome, which in case of insufficient therapy can lead to death.
