To report a case of biliary rhabdomyosarcoma (RMS) in a young child and highlight the role of multimodal imaging in diagnosis and staging, emphasizing the rarity of this condition.
Approach:
Case Presentation: A 2-year-11-month-old girl with obstructive jaundice was initially misdiagnosed as having choledochal cysts. Multimodal imaging including ultrasound, CT, MRI/MRCP, and PET-CT was utilized to identify a solid mass and guide further management.
Key Findings:
Biliary RMS is extremely rare, accounting for approximately 0.5% of pediatric RMS cases.
Multimodal imaging is crucial for accurate diagnosis and staging of biliary RMS.
Histopathology confirmed the diagnosis of embryonal RMS, classified as stage III, and the patient received vincristine, actinomycin D, and cyclophosphamide (VAC) chemotherapy.
Interpretation:
The case illustrates the importance of integrated imaging techniques in diagnosing biliary RMS, which can be misdiagnosed due to its rarity and presentation, highlighting the need for careful evaluation.
Limitations:
The study is based on a single case report, limiting generalizability and the ability to draw broader conclusions.
Long-term outcomes and prognosis are not discussed, which may affect understanding of the disease trajectory.
Conclusion:
Multimodal imaging is essential for timely diagnosis and staging of biliary RMS, facilitating accurate biopsy and management.
