Summary
This study details unusual features of oncocytomas, a benign kidney tumor. Findings include multiple tumors, bilateral occurrence, calcification, and association with renal cell carcinoma, aiding radiologists in diagnosis.
Area of Science:
- Nephrology
- Oncology
- Radiology
Background:
- Oncocytomas are benign renal neoplasms.
- Understanding their varied presentations is crucial for accurate diagnosis.
Observation:
- Nine oncocytomas across five patients exhibited unusual characteristics.
- These included multiplicity, bilaterality, calcification, and concurrent renal cell carcinoma.
Findings:
- Multiplicity observed in two patients.
- Bilaterality noted in two patients.
- Calcification present in one patient.
- Association with renal cell carcinoma in three patients.
Implications:
- Radiologists must recognize these uncommon features for correct diagnosis.
- Awareness can prevent misdiagnosis of benign oncocytomas.
