A boy aged 1 year 8 months underwent Tc-pertechnetate scintigraphy to evaluate the cause of bloody stool. On the initial images, there was an abnormal activity in the right abdomen, which changed location to the right groin in later images. A Meckel diverticulum was identified by histopathology examination. We concluded this case of moving Meckel diverticulum was caused by the synergy between an inguinal hernia and high abdominal pressure.
