    A false-negative technetium scan occurred in a child with Meckel's diverticulum, a congenital intestinal anomaly. This case highlights diagnostic challenges and reasons for inaccurate radioisotope imaging in pediatric patients.

    Area of Science:

    • Pediatric Surgery
    • Diagnostic Imaging
    • Gastroenterology

    Background:

    • Meckel's diverticulum is a common congenital malformation of the small intestine.
    • It can present with diverse symptoms, including gastrointestinal bleeding, mimicking other conditions.
    • Accurate diagnosis is crucial for timely surgical intervention.

    Observation:

    • A 17-month-old girl presented with recurrent bloody stools.
    • An initial technetium pertechnetate radioisotope scan for suspected Meckel's diverticulum was negative.
    • The patient subsequently underwent surgery for a confirmed Meckel's diverticulum.

    Findings:

    • The case details the diagnostic process and the reasons for the false-negative radioisotope scan.
    • Analysis of the false-negative examination provides insights into potential pitfalls in interpreting technetium scans for Meckel's diverticulum.

  • Surgical resection confirmed the presence of Meckel's diverticulum.

    • Implications:

    • This case underscores the importance of considering Meckel's diverticulum even with negative initial imaging.
    • Understanding the causes of false-negative scans can improve diagnostic accuracy in pediatric gastrointestinal bleeding.
    • Optimizing diagnostic strategies for Meckel's diverticulum is essential for preventing complications.
