P.320 Head and neck paragangliomas

Lemierre's Syndrome Originated from the Odontogenic Infection: A Case Report

“…LS is a severe complication of head and neck infections, resulting in lateral pharyngeal space infection and IJVT followed by septicaemia and metastatic infections predominantly in the lungs; the liver, spleen, kidney, meninges, heart, muscle, and skin can also be involved 2) . An extensive search of English literature from 4) to identify published cases, using multiple search criteria such as LS, Fusobacterium necrophorum, which is known as the most common bacterium causing LS, postanginal sepsis, and IJVT. A total of 99 cases of LS were found and reviewed.…”

“…Mononucleosis was associated with 12% of the cases; therefore, mononucleosis has been considered a predisposing factor to invasive LS. Although magnetic resonance (MR) has been introduced, recent literature suggests that color doppler ultrasonography and high-resolution CT are still important imaging tools in identifying IJVT and pulmonary septic emboli or metastases, which are critical in the spread of the disease 4) . A plain chest radiograph may not be effective in the early diagnosis of septic emboli 5) .…”

“…In most cases, F. necrophorum is the tentative causative microorganism 4) . Other pathogens that can cause LS include other Fusobacterium species, Bacteroides species, and groups A, B, and C Streptococcus.…”
