Abstract

A 62-year-old diabetic female was admitted to the hospital with fever and pain in both legs. Computed tomography scans of the abdomen revealed necrotizing fasciitis of the right thigh extending into the abdominal wall, and abscesses on the right psoas muscle. Magnetic resonance imaging showed increased T2 signal intensity along the peroneus muscle and fascia of the lower left leg. The patient received antibiotics and underwent debridement of the infected and necrotic tissue. Intra-abdominal abscesses were drained. Blood and pus cultures showed growth of Klebsiella pneumoniae, as had been suspected due to string test results showing hypermucoviscosity. Free-skin grafts were performed to repair tissue loss and the patient was subsequently discharged 82 days after admission. This represents the first reported case of necrotizing fasciitis and psoas muscle abscess caused by a hypervirulent strain of K. pneumoniae in Korea.
