    Intussusception in children can be identified via intravenous urography, revealing an opaque rim and target-like blush. This radiographic sign, though not a primary diagnostic tool, aids in recognizing intussusception when other methods are unavailable.

    Area of Science:

    • Pediatric Radiology
    • Gastrointestinal Imaging

    Background:

    • Intussusception is a common cause of bowel obstruction in infants and children.
    • Atypical clinical presentations can delay diagnosis.
    • Intravenous urography is not a standard diagnostic tool for intussusception.

    Observation:

    • Two pediatric cases of intussusception were initially evaluated with intravenous urography due to unusual symptoms.
    • Radiographic findings included an opaque rim outlining the intussusception, a result of total body opacification.
    • One patient exhibited a characteristic target-like blush on subsequent films.

    Findings:

    • The opaque rim and target-like blush on intravenous urography can indicate intussusception.
    • These findings suggest the need for further investigation, such as a barium enema.

    Implications:

    • Recognizing these signs during intravenous urography can lead to earlier diagnosis of intussusception.
    • This highlights the importance of considering alternative diagnoses and imaging findings in pediatric gastrointestinal emergencies.
    • While not recommended as a primary method, intravenous urography can provide diagnostic clues in specific clinical scenarios.
