Pneumopéritoine diagnostique uniquement au CT scan.

The authors report 3 cases of pneumoperitoneum due to visceral perforation and whose diagnosis was not performed on plain abdominal radiographs. In the 3 cases, pneumoperitoneum diagnosis and laparotomy decision were based on the results of an emergency abdominal CT Scan. Each time, the origin of the pneumoperitoneum was also clearly evidenced. When visceral perforation is suspected, we advice to perform CT Scan of the abdomen if pneumoperitoneum diagnosis has not been made by plain abdominal radiographs. CT Scan is an accurate exam for pneumoperitoneum diagnosis that permits undelayed surgical treatment
