Overview

Ultrasonography may also help in the detection of omphaloenteric (vitelline) duct remnants or cysts.

Ultrasound

Features in patients with Meckel's diverticulum on ultrasound include:[1][2]

  • Ultrasonography may also help in the detection of omphaloenteric (vitelline) duct remnants or cysts.[3]
  • Meckel's diverticulum is identified as a saccular, blind-ending structure located on the antimesenteric border of the ileum.
  • Meckel's 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, fecaliths, or foreign bodies.
