Trichobezoar is caused by hair ingestion that accumulates in the gastrointestinal tract. It is associated with psychiatric disorders. Occasionally, the hairs invade through pylorus and cause obstruction, which is known as Rapunzel Syndrome. A 9-year-old girl was admitted with signs of intestinal obstruction and a lump at her left side abdomen. Patient had history of trichotillomania and trichophagia. Abdominal ultrasonography and enhanced abdominal computed tomography were performed, which revealed a hair ball. Trichobezoar and Rapunzel Syndrome are bizarre and uncommon diseases. The case demonstrated that imaging modalities can accurately diagnose these diseases.
