Summary
This study presents two cases of renal cysts, one benign and one malignant, highlighting the diagnostic challenges in differentiating renal cell carcinoma from simple calcified cysts. Early detection and accurate diagnosis are crucial for appropriate patient management.
Area of Science:
- Nephrology
- Urologic Oncology
- Radiology
Background:
- Renal cysts are common, but calcified renal cysts can pose diagnostic challenges.
- Differentiating benign calcified renal cysts from renal cell carcinoma (RCC) is critical for treatment planning.
Observation:
- A 59-year-old male presented with an incidentally discovered calcified renal cyst; angiography revealed a hypervascular wall, leading to exploration and diagnosis of a benign cyst.
- A 27-year-old male with flank pain was suspected of having a renal cyst with RCC; exploration revealed a cystic lesion with RCC, treated with partial cyst wall excision.
Findings:
- Histological examination confirmed a benign calcified renal cyst in the first case.
- The second case revealed renal cell carcinoma associated with a cluster of cysts, treated successfully without nephrectomy.
Implications:
- Renal cysts associated with renal cell carcinoma, though rare, are increasingly reported.
- Advanced imaging and biopsy are essential for accurate diagnosis and management of complex renal cysts.
- Conservative management may be possible for selected cases of renal cell carcinoma associated with cysts.
