Abstract
A 31-year-old woman was admitted to our hospital because of fever, diarrhea and right lateral back pain. The white blood cell count was 15800/mm3 and the C-reactive protein level was 15.04mg/dl. Abdominal CT scan revealed high density suggestive of enterolith in the right lower abdomen and a retroperitoneal broad abscess from the level of the right kidney to pelvis along the right iliopsoas muscle. Retroperitoneal abscess probably arising from penetrated appendicitis was diagnosed. We performed retroperitoneal drainage by extrapentoneal route on the same day. Twenty-eight days after the drainage when the abscess shrank and inflammation subsided, laparotomy was done. An ileo-cecal resection was performed because we could not identify the appendix. Sixteen days after the latest surgery, the patient was discharged from our hospital. We report a case of a retroperitoneal abscess originating from penetrated appendicitis which was treated first by drainage only, and then by laparotomy.
