CT findings of small bowel trichobezoar.

A 14-year-old girl presented to our emergency room with abdominal pain and persistent vomiting. A plain radiograph of the abdomen showed features of small bowel obstruction, with dilated loops of small bowel and a mottled gas and debris pattern in the stomach and right lower quadrant. A CT scan of the abdomen and pelvis obtained to exclude appendicitis showed the distinctive appearance of a trichobezoar. A preoperative diagnosis of gastric and intestinal trichobezoar was made.
