There is a focus of increased isotope uptake seen in the right lower quadrant and inferior to the iliac vessels on both the frontal and oblique views, most consistent with a Meckel's diverticulum.
Meckel diverticulum is a congenital intestinal diverticulum due to fibrous degeneration of the umbilical end of the omphalomesenteric (vitelline) duct that occurs around the distal ileum. It is considered the most common structural congenital anomaly of the gastrointestinal tract.
