Meckel's diverticulum is the most common congenital anomaly of gastrointestinal tract, which results from incomplete involution of the proximal part of the vitelline duct during weeks 5-7 of fetal development. Giant Meckel's diverticulum more than 5 cm in length is relatively rare and may be associated with small bowel obstruction. Here we report Giant Meckel's diverticulum in 11 year old male who presented with the symptoms of acute abdomen with intermittent subacute small bowel obstruction. Patient presented with muscle guarding and tenderness. CT abdomen revealed a large outpouching round lesion in distal ileum intermittently compressing the small bowel that was suggestive of Giant Meckel's diverticulum. The morphology, pathology and complications of Giant Meckel's diverticulum is important for radiologist and surgeons for successful management of patient.
