Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity. The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.

Pneumoperitoneum, usually seen as free air under the diaphragm, is a finding that can be seen on plain abdominal radiographs, signifying a leakage of air, usually from a perforation in the gastrointestinal tract. There are several other potential pathways from other body compartments for air to ente …
