Abstract
A 77-year-old woman was admitted to hospital because of vomiting and abdominal pain. An abdominal computed tomography examination revealed the presence of ascites in the pelvic cavity. Severe tenderness, muscular defense, and a Blumberg sign were observed throughout the abdomen. The patient was diagnosed as having diffuse peritonitis caused by a perforation of the digestive tract and underwent an emergency operation. During the operation, a hole was found in the uterus body ; consequently, the diagnosis was changed to diffuse peritonitis caused by a pyometra-induced perforation of the uterus. A simple hyster-ectomy was performed. Diffuse peritonitis arising from a pyometra-induced perforation is rare, but this condition should be included in a differential diagnosis of in acute abdomen in elderly woman.
