Description

<p>A 28-year-old man without remarkable medical history was admitted to our hospital with acute abdominal pain and bloody stools. Abdominal computed tomography showed the patient's ileum to have invaginated into the ascending colon at where multiple gaseous cysts were confirmed. The patient was considered to be a candidate for emergency surgery, on account of having bowel ischemic symptoms. During surgery, some small palpable elastic-soft tumors were found in the cecum, so we performed ileocecal resection because a possibility of malignancy could not be ruled out. Grossly the resected specimen revealed the presence of multiple polyps on the cecum mucosa. Histopathological findings showed severe edema and cysts of variable sizes in the submucosal area, in addition to bleeding and congestion in the lamina propria mucosae area. These findings led to the diagnosis of intussusception caused by pneumatosis cystoides intestinalis (PCI).</p><p>PCI is a disease characterized by the presence of multiple gaseous cysts beneath the serosa and mucosa in the intestinal wall, and the etiology has been unclear. PCI associated with intussusception is a rare condition. Here we report a case along with a review of the literature.</p>
