We present two cases of Pneumatosis Cystoides Intestinalis (PCI) involving the small intestine: emergency operations was mandatory. At surgery, the affected ileal segments were resected. After surgery, clinical courses were uneventful. PCI is a sign, not a disease, and therefore its significance is directly related to the patient's overall clinical status. Treatment is not indicated in asymptomatic patients, whereas immediate surgical intervention is necessary in patients with abdominal catastrophes.
