Pneumoperitoneum secondary to non-specific intestinal cystic pneumatosis: A case report

Intestinal cystic pneumatosis is a pathological entity of strange presentation, characterized by the presence of extraluminal gas located at the level of the submucosa and/or subserosa of the intestinal walls, forming cystic lesions that generally vary from 0.5 to 2.0 cm presenting an incidence around 0.03% in the general population. We present the case of a patient who presented to the emergency department for sudden abdominal pain, diffuse signs of peritoneal irritation, and a history of previous laparotomy for perforated gastric ulcer as the only relevant history. An X-ray was performed showing pneumoperitoneum, with subsequent histopathological diagnosis of cystic intestinal pneumatosis.
