Pneumatosis intestinalis (PI) is defined as the presence of gas within the serosal or mucosal layer bowel wall. This sign is usually found upon radiographic imaging and is most commonly secondary to acute gastro-intestinal ischaemia. Fifteen per cent of cases can present with a primary condition called pneumatosis cystoides intestinalis (PCI). PCI is usually a benign condition and patients are ...

An asymptomatic 65-year-old man with an unremarkable medical history underwent colonoscopy for colon cancer screening. This showed multiple bumps in the bowel wall of variable size (2–25mm) protruding into the lumen. These appeared to be interconnected and covered with normal-looking mucosa, with no areas of sparing in the sigmoid and proximal rectum (●" Fig.1). No other lesions of the mucosa w...

PNEUMATOSIS CYSTOIDES intestinalis is a rare condition in which gas-containing cysts arise in the intestinal wall and elsewhere within the abdominal cavity. The cysts vary in size from a millimetre to several centimetres in diameter and may occur in large numbers. In most cases the cysts are subserous but occasionally they arise in the submucous layer of the intestine. The pneumatosis is most o...

a rare condition in which multiple submucosal or subserosal air-filled cysts develop in the submucosa or in subserosa of the colon [1]. The etiological mechanisms are not clear. PCI is associated with raised intra-abdominal pressure because of ileus surgery, colonoscopy, pulmonary diseases, connective tissue disorders, ingestion of carbohydrates such as lactulose and sorbitol, use of α-glucosid...

OBJECTIVE The purpose of this article is to study the imaging features, management, and outcome of pneumatosis intestinalis and bowel perforation associated with molecular targeted therapy. MATERIALS AND METHODS In this retrospective study, 48 patients with cancer who developed pneumatosis or intestinal perforation were found by searching a radiology database. Of these patients, 24 patients (...

Pneumatosis cystoides intestinalis (PCI) is an uncommon condition of unknown aetiology. Bacterial gas production may be an important aetiological factor, but experimental evidence in humans has been lacking. We have studied breath hydrogen excretion as an index of bacterial gas production in 12 patients with PCI and have shown that four out of five with demonstrable cysts produced unusually hig...

A 56-year-old woman was admitted to our hospital for treatment of non-specific interstitial pneumonitis (NSIP). The patient started prednisone treatment, but one month later treatment with voglibose, an alpha-glucosidase inhibitor (alpha-GI), was started because of prednisone-induced diabetes mellitus. One week later, a massive volume of free air below the diaphragm was detected by a chest X-ra...
