Insights

A sodium pertechnetate Tc 99m scan diagnosed Meckel diverticulum in a child with rectal bleeding. This scan is valuable for unexplained bleeding in children, despite potential false negatives.

Area of Science:

  • Pediatric Surgery
  • Diagnostic Imaging

Background:

  • Recurrent rectal bleeding in children often presents a diagnostic challenge.
  • Meckel diverticulum is a congenital anomaly that can cause significant gastrointestinal issues.

Observation:

  • A 2-year-old child presented with recurrent, painless rectal bleeding.
  • Preoperative diagnosis was crucial for effective management.

Findings:

  • A sodium pertechnetate Tc 99m scan successfully identified Meckel diverticulum as the source of bleeding.
  • The scan's utility is highlighted despite a known false-negative rate of approximately 50%.

Implications:

  • The Tc 99m scan should be considered in the workup of unexplained pediatric rectal bleeding.
  • Early diagnosis of Meckel diverticulum can prevent complications and guide surgical intervention.
