Gas Gangrene of the Spleen Caused by Clostridium perfringens After Mild Blunt Trauma.

Splenic gas gangrene caused by  Clostridium perfringens  is rare. A 73-year-old woman was referred to our hospital because of fatigue, dyspnea, and left hypochondrial pain. She had a history of blunt trauma to the left abdomen eight days ago. She presented with hypoxemia and a high inflammatory response on blood tests. A CT showed left pleural effusion and gas in the spleen. She was treated with antimicrobials and underwent splenectomy.  C. perfringens  was identified from blood and intraoperative ascites cultures. She recovered and was discharged on day 34 of hospitalization. As  C. perfringens  is part of the normal gut microbiota and can translocate to other parts of the body, this bacterium should be considered a splenic abscess pathogen when an intracorporeal anaerobic environment is suspected.
