Lemierre syndrome caused by Klebsiella pneumoniae complicated by epidural abscess - Case report.

Abstract

Klebsiella pneumoniae is an extremely rare case of the Lemierre syndrome, which is characterized as septic thrombophlebitis of the jugular vein as a consequence of oropharyngeal infection. We present a unique case of Lemierre syndrome caused by Klebsiella pneumoniae, complicated by epidural abscess. The patient presented with fever, severe nuchal pain and stiffness and mild sore throat and headache. Computed tomography revealed a neck abscess localized dorsally to a left mandibular ramus and continuing caudally along the sternocleidomastoid muscle, thrombosis of the left internal jugular vein and fluid collection in the epidural space. Viewed under magnetic resonance imagining, the effusion had the character of an epidural abscess. Cultivation of oropharyngeal swab and blood cultures revealed Klebsiella pneumoniae. The neck abscess was surgically drained, and the patient was treated with a combination of parenteral antimicrobials until complete clinical and radiologic remission. This case highlights the importance of also covering the gram-negative facultative anaerobic rod spectrum in the empiric antimicrobial treatment of Lemierre syndrome.
