OBJECTIVE: Our aim was to review the imaging findings and outcomes of @entity1 with nontraumatic spontaneous intramural small-bowel @entity1410 . MATERIALS AND METHODS: We retrospectively reviewed the records and radiologic studies of 13 @entity1 with known intramural small-bowel @entity548 . RESULTS: The mean age at presentation was 64 years. Sixty-two percent of @entity1 had @entity1229 @entity137 . The diagnosis was evident on CT performed in all @entity1 . @entity1744 was present in 85% of @entity1 , and @entity253 was present in 8%. A single @entity1410 was present in 85% of @entity1 , and multiple @entity1410 were present in 15%. The jejunum was the most common site of the @entity1410 (69%), followed by the ileum (38%) and duodenum (23%). The @entity1410 extended into the cecum in 15% of @entity1 . The estimated average length of the @entity1410 was 23 cm, and the shortest segment was 8 cm. Resolution of the @entity1410 was seen on CT as early as 1 week after onset. Eleven @entity1 (85%) with non-extensive @entity1410 were dismissed from the hospital without any short- or long-term complications (mean follow-up, 35 months). Two @entity1 with extensive @entity1410 involving more than half the length of the small intestine died. CONCLUSION: Spontaneous intramural small-bowel @entity1410 is rare. It occurs in @entity1 who receive excessive anticoagulation with @entity1229 or who have some other risk factor for @entity548 . CT characteristics include circumferential wall thickening, intramural hyperdensity, luminal narrowing, and @entity1321 . Early diagnosis is crucial because most @entity1 are treated nonoperatively with a good outcome.
