Giant rectosigmoid lithobezoar in a child: four significant clues obtained from history, abdominal palpation, rectal examination and plain abdominal X-ray

Abstract Colonic bezoars, especially lithobezoars are very rare findings in children. We report a 6-year-old girl with a giant rectosigmoid lithobezoar. History of constipation and pica, abdominal palpation of intraluminal fecoliths, a prickly hard mass found on rectal examination and plain abdominal X-ray showing radioopaque innumerable calculi scattered in colon and congregated in rectosigmoid region provide important clues for diagnosis of colonic lithobezoar.
