Abstract

Klebsiella pneumoniae is known to cause an invasive syndrome characterized by primary liver abscess associated with metastatic infection. The characteristics of the metastatic infection involving the musculoskeletal system in this invasive syndrome are not well understood. The authors present a case report of a patient who developed abscesses of the lower extremities along with abscesses of multiple organs, such as the liver and eye, caused by K. pneumonia. The patient was diagnosed early, and the infection was successfully controlled after several surgical treatments.
