To provide clinical reference regarding the imaging findings and diagnosis of primary renal synovial sarcoma, emphasizing the significance of accurate diagnosis.
Key Findings:
Primary renal synovial sarcoma is a rare malignancy, accounting for less than 2% of renal tumors.
Imaging features of renal synovial sarcoma can mimic those of renal cell carcinoma, complicating diagnosis.
The diagnosis was confirmed through the identification of the SS18-SSX2 fusion gene, which has significant implications for treatment.
Interpretation:
This case highlights the importance of combining imaging, immunohistochemistry, and genetic analysis for accurate diagnosis of rare renal tumors, which can lead to better treatment strategies.
Limitations:
The rarity of primary renal synovial sarcoma limits the generalizability of findings and may introduce biases.
Long-term follow-up data is needed to assess the prognosis and potential recurrence.
Conclusion:
This case underscores the need for awareness of primary renal synovial sarcoma in differential diagnoses of renal masses and the utility of genetic testing in confirming rare malignancies, which can improve patient outcomes.
