title: Dumbbell-Shaped Activity on Meckel's Scintigraphy Caused by Hiatal Hernia.
abstract: A 13-month-old underwent Meckel's scintigraphy to evaluate a cause of melena. The images revealed a dumbbell-shaped activity. One side of dumbbell was located in the midline lower chest, whereas another side with similar intensity was in the normal location of the stomach. A subsequent contrast CT demonstrated a large hiatal hernia.
