Diagnosis With Brief Discussion
- Diagnosis
- Lemierre syndrome
- Radiologic Findings
- Fig 1. Mutlifocal lung nodules in both lungs
Fig 2. Rt IJV thrombophelbitis
Fig 3. Multiple subpleural nodules, some with cavities, in both lungs.
- Brief Review
- Oropharyngeal infection (m/c) → thrombophlebitis of the IJV → systemic metastatic infection (lung, joint, brain..), anaerobic sepsis
Incidence decreased dramatically after introduction of antibiotics
Affects mainly healthy people (2nd, 3rd decades), M > F
Main organism: Fusobacterium necrophorum (gram-negative anerobe)
Imaging features
Chest x-ray
Numerous ill-defined rounded opacities, pleural effusion
CT
Primary infection focus (oropharyngeal infection, peritonsillar area)
Filling defect in the IJV
Multiple peripheral, round/wedge-shaped opacities that progress to cavitation (septic emboli), abscess
