PURPOSE: To assess the computed tomographic (CT) features of abdominopelvic @entity5850 involving the gastrointestinal tract. MATERIALS AND METHODS: CT scans were analyzed in 18 @entity1 with pathologically proved abdominopelvic @entity5850 involving the gastrointestinal tract. Eight @entity1 had a history of using intrauterine contraceptive devices. Bowel site, wall thickness, length, bowel involvement patterns, inflammatory infiltration, and features of peritoneal or pelvic mass, if present, were evaluated at CT. RESULTS: Of the gastrointestinal tract, the sigmoid colon was most commonly involved (50%). All @entity1 showed concentric (n = 15) or eccentric (n = 3) bowel wall thickening, with a mean thickness of 1.2 cm and a mean length of 8.3 cm. The thickened bowel enhanced homogeneously in nine @entity1 and heterogeneously in the other nine. Inflammatory infiltration was mostly diffuse and severe. In 17 @entity1 , a peritoneal or pelvic mass (mean maximum diameter, 3.2 cm) was seen adjacent to the involved bowel and appeared to be heterogeneously enhanced in most cases; infiltration into the abdominal wall was seen in four @entity1 . CONCLUSION: @entity5850 should be included in the differential diagnosis when CT scans show bowel wall thickening and regional pelvic or peritoneal mass with extensive infiltration, especially in @entity1 with @entity490 , @entity221 , @entity491 , or long-term use of intrauterine contraceptive devices.
