Abstract

A 47-year-old woman with scleroderma was referred for evaluation of recurrent episodes of small-bowel obstruction. Physical examination revealed sclerodactyly, and the abdomen was distended with tympany to percussion and a paucity of bowel sounds. On computed tomographic enterography there was dilatation of the entire small bowel with narrow separation between valvulae conniventes (FiguresA and B; arrows). This radiographic finding is termed the hide-bound bowel sign and is the radiographic representation of the smooth muscle atrophy and fibrosis that occurs as a result of foreshortening of small bowel in scleroderma.
