Summary
Alveolar soft part sarcoma (ASPS) in the thigh with lung metastases was diagnosed in a young woman. Dynamic contrast-enhanced MRI proved valuable for assessing chemoembolotherapy effectiveness in this rare cancer case.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Background:
- Alveolar soft part sarcoma (ASPS) is a rare, aggressive soft tissue malignancy.
- ASPS commonly affects young adults and can metastasize to distant sites, including the lungs.
Observation:
- A 22-year-old female presented with a thigh mass and subsequent lung metastases.
- Diagnostic imaging modalities, including digital subtraction angiography (DSA) and magnetic resonance imaging (MRI), were employed.
Findings:
- Both DSA and MRI were instrumental in diagnosing alveolar soft part sarcoma.
- Dynamic contrast-enhanced MRI provided crucial insights into the efficacy of chemoembolotherapy treatment.
Implications:
- This case highlights the diagnostic utility of advanced imaging in ASPS.
- Effective monitoring of treatment response, particularly with dynamic contrast-enhanced MRI, is vital for managing metastatic ASPS.
