Case report: "Popcorn" dystrophic ileal calcification in a patient with Crohn's disease.

Small bowel calcification is a rare finding, often associated with chronic infection or small intestinal neoplasms. The authors report a patient who developed dystrophic ileal calcification in the setting of medically refractory Crohn's disease. The patient had longstanding, obstructive ileal Crohn's disease, treated with corticosteroids for a 10-year period. Diffuse terminal ileal calcification was evident on radiographic studies, including plain films as well as abdominal CT scan. The patient underwent successful resection of the diseased segment of small bowel and has done well over the ensuing 3-year period. Dystrophic calcification is a rare complication of long-standing chronic inflammation in Crohn's disease that may occur in the absence of adenocarcinoma or chronic infection.
