CT findings in XXXX involving the gastrointestinal tract.

@entity1 @entity3329 @entity3191
PURPOSE: To evaluate whether computed tomography (CT) accurately depicted gastrointestinal tract involvement in @entity3191 ( @entity3191 ). MATERIALS AND METHODS: CT scans were retrospectively reviewed in 14 @entity1 with pathologically proved PTCLs of the gastrointestinal tract for the following considerations: sites, patterns of involvement (ie, morphologic features, bowel wall thickness or mass size, and contrast enhancement pattern), and ancillary findings at other sites (ie, @entity3329 , bowel perforation, and involvement of other organs). RESULTS: @entity3191 involved the stomach in three @entity1 , the small intestine in eight, both the stomach and the small intestine in one, and the sigmoid colon in two; multifocal involvement was seen in three (21%) @entity1 . CT failed to demonstrate the bowel lesions in three of 14 @entity1 . At CT, 11 @entity1 had gastric or bowel wall thickening (n = 10) and a polypoid mass (n = 1). In 10 @entity1 , the gastric or bowel wall thickening was mild (<1 cm) in six, moderate (1-2 cm) in three, and severe (>2 cm) in one. Lymphadenopathy was noted in nine (64%) @entity1 , with the nonbulky type in eight and the bulky type in one. Bowel perforation occurred in four (29%) @entity1 . Other organs were involved in eight (57%) @entity1 . CONCLUSION: CT can depict @entity3191 involving the gastrointestinal tract if it is not confined to the mucosa. There is a tendency toward preferential jejunal or duodenal involvement, as well as bowel perforation.
