Swallowed toothbrushes were noted in the esophagus of one teenager and the stomach of two others with bulimia. The presence of a toothbrush in the lumen of the gastrointestinal tract should make the radiologist suspicious of bulimia/anorexia nervosa. A toothbrush shows a characteristic radiographic image with parallel rows of short metallic radiodensities due to the metallic plates that hold the bristles in place.
