    Abstract:
    OBJECTIVE: The purpose of this article is to report the CT findings of pathologically proven diaphragm disease in the small bowel. MATERIALS AND METHODS: A retrospective review identified 12 patients with pathologically proven small-bowel diaphragm disease who underwent CT within 6 months of surgical resection. Two radiologists, who were unblinded to pathologic and clinical findings, evaluated CT examinations for imaging findings of disease extent, appearance, and location. Clinical history and postoperative follow-up were also performed. RESULTS: The most common presenting symptoms were abdominal pain (7/12 [58%]) and anemia (5/12 [42%]). Long-term use of nonsteroidal antiinflammatory drugs was documented in 58% (7/12) of patients. The most common location of small-bowel diaphragms was the ileum (8/12 [67%]). The CT findings were abnormal in 92% (11/12) of patients. The most common CT findings were small-bowel strictures (11/12 [92%]) and focal (median length, 1 cm) bowel wall thickening (8/12 [67%]). Other less common CT findings included mucosal hyperenhancement (6/12 [50%]), small-bowel dilatation (5/12 [42%]), and video capsule retention (6/9 [67%]). Postoperative follow-up in 11 patients found recurrent symptoms in four patients. CONCLUSION: Small-bowel diaphragm disease should be considered in patients with a history of long-term use of nonsteroidal antiinflammatory drugs, chronic abdominal pain, and anemia who present with CT findings of short, symmetric ileal strictures and focal bowel wall thickening.
