Lemierre syndrome: forgotten but not extinct--report of four cases.

Four cases of Lemierre syndrome are reported in which metastatic abscesses resulted from septic thrombosis of the internal jugular vein secondary to bacterial pharyngitis. While chest radiographic findings were nonspecific, results of computed tomography (CT) of the thorax in each case were highly suggestive of septic pulmonary emboli. Internal jugular venous thrombosis was demonstrated at ultrasonography and contrast material-enhanced CT.
