[Lemierre's syndrome]

Lemierre's disease: a case with bilateral iliopsoas abscesses and a literature review

Lemierre's disease is characterized by sepsis, often with an oropharyngeal source, secondary septic emboli and internal jugular vein thrombosis (Lancet 1:701-3, 1936. Clin Microbiol Rev 20(4):622-59, 2007). Septic emboli affecting many bodily sites have been reported, including the lungs, joints, bones, and brain. The case report describes an unusual case of Lemierre's disease in a 64 year old gentleman causing profound sepsis, acute kidney injury, bilateral iliopsoas abscesses and a right hand abscess. To our knowledge, this is the first reported case of Lemierre's disease in the context of bilateral psoas abscesses, and highlights the ambiguity surrounding the definition of Lemierre's disease. The clinical literature review highlights the difficulty in definitively diagnosing the condition and offers some suggestions for recognising and refining the diagnostic criterion of Lemierre's.

[A parotitis as primary infection of Lemierre's syndrome]

Lemierre's syndrome is a classical presentation of human necrobacillosis. It is characterized by a primary infection in the face including a septic thrombophlebitis of the internal jugular vein and disseminated metastatic abcesses. Fusobacterium necrophorum is the main pathogen found in that syndrome. The diagnosis is based on clinical features, then on the microbiology with positive anaerobic blood cultures as key role and finally on the computed tomography. Most of the time a well-chosen antibiotic treatment against anaerobic pathogens and Gram negative bacilli is efficient but surgery can be useful. We report a case of a 73 years old man, which seems to be unique because it is the first case reported of a Lemierre's syndrome characterized by a parotitis infected by F. necrophorum.

[Use of ECMO as a salvage therapy for refractory hypoxia secondary to a Lemierre's syndrome]

We reported the case of a young adult with a Lemierre syndrome, which was complicated by septic shock and ARDS. Because of rapid onset of a life-threatening hypoxemia (PaO(2)/FiO(2)=60) in the course of the ARDS despite mechanical ventilation, ECMO was started with jugular and femoral cannulas, as rescue therapy. Good control of hypoxemia was obtained and ECMO was set up for six days. No significant complication was observed. The course was nevertheless complicated by acute renal failure and a pleural fistula that necessitated separate-lung ventilation during 24 hours. After 48 days left in the ICU, the patient was sent to a rehabilitation unit.
