Lemierre's syndrome: septic internal jugular thrombophlebitis secondary to pharyngitis


Acute thrombosis of the right internal jugular and right brachiocephalic vein, right subclavian and axillary veins with inflammatory peri-vascular and neck spaces hypoattenuating lesion and collection as well as a small retropharyngeal marginally enhancing collection (likely an abscess / pseudo-abscess) as described consistent with septic thrombosis of the internal jugular vein (Lemierre's syndrome).

Lemierre's syndrome refers to the purulent or septic thrombophlebitis of the internal jugular vein as a complication of pharyngitis. Lemierre's disease could be even further complicated by distant metastatic abscesses in the lungs with septic pulmonary emboli, brain abscesses or elsewhere (septic arthritis can lead to acute osteomyelitis).
