A 9-year-old boy had a 1-year history of pallor, anemia, malnutrition and fainting. One day before admission he had severe rectal bleeding with abdominal pain that required transfusion of 2500 mL blood based on diagnosis of hemorrhagic anemia. On examination, he appeared with pallor but nothing else of note. The hemoglobin was 5.3 g/100 mL. The stool specimen was positive for guaiac. Tc-99m pertechnetate scintigraphy was performed dynamically. Cluster and stripy abnormal radioactivity was seen in the right and low abdomen between 5 and 60 minutes post injection. At operation, Meckel diverticulum and intestine duplication with cystic dilatation were removed. The coexistence of Meckel diverticulum and intestine duplication is probably rare.
