This gastrointestinal bleeding originates mostly from the colon. Also, the bleeding can occur in the small intestine in rare cases. A 25- y-old man present at the emergency room at King Saud Medical City complained because he noticed blood in his stool. The final impression for CT angiogram was a sign of Meckel’s Diverticulum which needed to be confirmed by nuclear medicine scan Tc99m pertechnetate. Tc99m pertechnetate helps diagnose MD noninvasively and has a potential role in the evaluation of Meckel’s Diverticulum even with adult patients.
