Other Imaging Findings
- Meckel diverticulum is identified as a saccular, blind-ending structure located on the antimesenteric border of the ileum.
- Meckel diverticulum is usually found in the right lower quadrant and pelvic region.
- The junction of the diverticulum with the ileum may show a mucosal triangular plateau or triradiate fold pattern (represents the site of omphalomesenteric duct attachment to the ileum).
- Filling defects within the diverticulum may represent enteroliths, fecoliths, or foreign bodies.
- Technetium-99m pertechnetate scintigraphy is the modality of choice for evaluating pediatric patients with gastrointestinal hemorrhage and a suspected Meckel diverticulum.
- A Meckel diverticulum containing gastric mucosa will manifest as a small rounded area of increased activity in the right lower quadrant.
- Normal activity will simultaneously appear in the stomach.
