Lemierre's syndrome.

Postanginal sepsis, or Lemierre's syndrome, is rare but with life-threatening potential involving mainly infants and adolescents. The morbidity or mortality is caused mainly by lack of knowledge of the syndrome. The 18-year-old boy described here developed a jugular thrombosis 7 days after an angina. Fusobacterium necrophorum was isolated from the culture of the excised jugular vein. Secondary embolism involved the lungs, associated with an iliac osteomyelitis and sacroiliitis. Computed tomography was used for diagnosis and follow-up.
