    Abstract:
    Pneumatosis intestinalis is the presence of gas in the bowel wall and is divided into two categories: life-threatening pneumatosis intestinalis and benign pneumatosis intestinalis. Pneumatosis cystoides intestinalis is a rare condition characterized by gas-filled cysts in submucosa and subserosa. The pathogenesis is unclear, although some causes have been theorized. The presenting clinical findings may be very heterogeneous. Intestinal pneumatosis may lead to various complications. Distinguishing between pneumatosis cystoides intestinalis and life-threatening pneumatosis intestinalis may be challenging, although computed tomography scan allows the detection of additional findings that may suggest an underlying, potentially worrisome cause of pneumatosis intestinalis. To correctly manage the patients affected with this disease is important to differentiate the two types of pneumatosis. The patients with pneumatosis cystoides intestinalis are usually treated conservatively; the surgical treatment is reserved for complications. We described a case of a patient with pneumatosis cystoides intestinalis and gastric perforation. The medical history of the patient revealed a breast cancer treated with mastectomy and chemotherapy; the patient did not report a history of gastrointestinal disease. The abdomen CT showed abscess formation at the level of the antro-pylorus, linear pneumatosis in the gastric wall, and free abdominal air. Multiple small air bubbles was observed in intestinal wall. The intestinal wall was not thickened with normal contrast mucosal enhancement. CT examination showed neither mesenteric stranding nor portal venous gas embolism. The findings of the surgery were gastric perforated peptic ulcer and benign pneumatosis intestinalis.
