Clostridium septicum myonecrosis following chemotherapy

Excerpt

Laboratory findings were profound neutropenia (neutrophil count 0.0 × 109/L), thrombocytopenia (platelet count 17 × 109/L), and elevated CRP (13.22 mg/dL). Computed tomography of the abdomen and pelvis showed extensive abnormal gas around the left ilium causing its destruction, with necrosis of adjacent gluteal muscles, and gas extending into the left sacrum, pubic ramus and right inferior epigastric vein (Fig. 1). The patient deteriorated rapidly with septic shock and died 10 h later despite broad-spectrum intravenous antibiotics and inotropic support in the intensive care unit. Blood cultures later grew Clostridium septicum, as well as Staphylococcus aureus and Gram-variable bacilli.
