Short Occult Retractile Fibrous Scar Causing Exclusive Retrograde Stenosis of the Sigmoid Colon: An Incidental Diagnosis Nineteen Years After a Single Episode of Colonic Diverticulitis.

We report a rare case of purely retrograde stenosing stricture of the sigmoid descending colonic junction fortuitously diagnosed during the waning of a failed virtual colonoscopy in a 69-year-old patient. The rather asymptomatic patient was addressed to investigate a positive fecal occult blood test. He had suffered a single acute colonic diverticulitis episode 19 years before.

Perforation of the gastrointestinal tract caused by inadvertent ingestion of blister pill packs: report of two cases diagnosed by MDCT with emphasis on maximal intensity and volume rendering reformations.

The first patient presented with obstruction followed by anemia and finally perforation of the small bowel. The second presented with rapidly lethal mediastinitis due to a large perforation of the lower esophagus.
