    Pediatric radiology·1994

    Choledochal cysts are rare, primarily affecting children, and often present with vague symptoms. Advanced imaging like real-time sonography and cholescintigraphy are now key for accurate preoperative diagnosis.

    Area of Science:

    • Pediatric Radiology
    • Gastrointestinal Imaging
    • Diagnostic Imaging

    Background:

    • Choledochal cysts are uncommon congenital biliary malformations, predominantly diagnosed in pediatric populations.
    • Nonspecific clinical presentations necessitate robust radiologic evaluation for accurate diagnosis.
    • Traditional imaging modalities like abdominal roentgenograms and upper GI contrast studies can suggest mass effect but lack specificity.

    Purpose of the Study:

    • To summarize radiologic findings in pediatric choledochal cyst cases.
    • To evaluate the diagnostic utility of various imaging techniques for choledochal cysts.
    • To highlight advancements in non-invasive imaging for preoperative diagnosis.

    Main Methods:

    • Review of radiologic findings in six pediatric patients with choledochal cysts.

  • Assessment of conventional imaging: abdominal roentgenogram, intravenous urography, hepatic angiography, sonography, computerized tomography, and upper GI contrast studies.
  • Evaluation of newer techniques: real-time sonography and cholescintigraphy (using technetium Tc 99m iminodiacetic acid derivative).

    • Main Results:

    • Abdominal masses and duodenal displacement were noted on initial imaging.
    • Intravenous cholangiography and oral cholecystography showed limited diagnostic value and potential toxicity in children.
    • Real-time sonography and cholescintigraphy provided specific preoperative diagnoses, obviating the need for invasive procedures.

    Conclusions:

    • Real-time sonography and cholescintigraphy are highly effective for specific preoperative diagnosis of choledochal cysts in children.
    • These advanced imaging modalities reduce the necessity for invasive diagnostic procedures like arteriography and cholangiopancreatography.
    • Radiologic assessment remains crucial for diagnosing choledochal cysts, with modern techniques offering improved accuracy and safety.
