Abstract
A 29-year-old woman was admitted to the hospital because of epigastric pain and nausea. We recognized tenderness and muscular defense of the upper abdominal lesion. chest and abdominal X-P revealed free air in the abdominal cavity. We suspected gastric or duodenal perforation, and an operation was done. There was a gush of gas upon opening the peritoneum, but there was no ascites, perforation, or peritonitis.
She had no significant past history and we assumed that the gas had entered the peritoneal cavity via the genital tract. There was no evidence of indicate genital entrance of gas, however, so we diagnosed spontaneous pneumoperitoneum. The case is very rare and of particular interest for investigating the eiology of adult pneumoperitoneum.
