A 5-year-old girl is brought to the pediatrician for evaluation of abdominal pain and bloody stools. The symptoms began three-weeks ago. The abdominal pain is intermittent and usually self-resolves within an hour. Past medical history is noncontributory. She has been meeting all developmental milestones. Physical examination reveals a nontender and nondistended abdomen with normal bowel sounds. Laboratory testing reveals the following:
A radiolabeled technetium-99 scan is performed and reveals increased uptake in a structure located in the right lower abdominal quadrant. The walls of this structure will most likely consist of which of the following?
| Laboratory value | Result |
| Hemoglobin | 15.2 g/dL |
| Platelet count | 260,000/mm3 |
| Prothrombin time | 14 seconds |
| Partial thromboplastin time | 32 seconds |
A radiolabeled technetium-99 scan is performed and reveals increased uptake in a structure located in the right lower abdominal quadrant. The walls of this structure will most likely consist of which of the following?

Summary
A Meckel's diverticulum is a malformation of the gastrointestinal system, characterized by a small pouch that forms on the wall of the distal ileal part of the small intestine. It occurs when during fetal development, part of the intestine fails to close up properly.
Meckel's diverticulum can cause problems if food or other material becomes trapped in the pouch, leading to bowel infection or even perforation. Surgery is usually needed to remove a Meckel diverticulum.
