Lemierre's syndrome: a case report.

We report a case of Lemierre's syndrome with a pleuropulmonary complication. Lemierre's syndrome is a rare etiology of lung abscess. The diagnosis is clinical and microbiological (anaerobic organisms). This syndrome associates an acute oropharyngeal infection with septic thrombophlebitis of the internal jugular vein (sometimes many days before the lung lesion) and pulmonary abscess formation. Clinicians should be aware of this syndrome that is fatal in 10% of patients, usually after delayed or missed diagnosis. The frequency of Lemierre's syndrome would be higher if antibiotics were given only to pharyngitis patients positive for streptococcus.
