Summary
Computed tomography (CT) accurately excludes retroperitoneal lymphadenopathy in children with Hodgkin's disease. When performed correctly, CT is reliable for staging, especially in older children.
Area of Science:
- Pediatric Oncology
- Diagnostic Imaging
Background:
- Accurate staging of Hodgkin's disease in children is crucial for treatment planning.
- Retroperitoneal and pelvic lymphadenopathy are common sites of disease involvement.
Observation:
- This study compared abdominal computed tomography (CT) with bipedal lymphangiography in 17 children with Hodgkin's disease.
- The correlation between CT and lymphangiography was assessed to determine CT's accuracy in detecting lymphadenopathy.
Findings:
- Excellent correlation was observed in 82% of patients.
- CT accurately excluded lymphadenopathy when bowel and vasculature were adequately visualized.
- Lymphangiography identified pelvic lymphadenopathy missed by initial CT interpretation in 12% of cases.
Implications:
- Abdominal CT is a reliable imaging modality for excluding retroperitoneal and pelvic lymphadenopathy in pediatric Hodgkin's disease.
- Careful attention to technique, including adequate opacification, enhances CT accuracy.
- CT may be particularly accurate in older children for staging this condition.
