Summary
Renal hemangiomas, rare benign kidney tumors, can present as suspicious cortical lesions. This case highlights how renal hemangioma can mimic kidney cancer on imaging, necessitating careful pathological evaluation.
Area of Science:
- Nephrology
- Urologic Oncology
- Diagnostic Imaging
Background:
- Renal cortical hemangiomas are uncommon benign vascular malformations.
- Distinguishing them from renal cell carcinoma is crucial for appropriate patient management.
Observation:
- A 38-year-old patient presented with symptoms of recurrent renal colic.
- Computed tomography (CT) revealed a cortical lesion in the right kidney, suspicious for malignancy.
Findings:
- The patient underwent a nephrectomy for the suspected renal carcinoma.
- Pathological examination identified a 2.7 cm circumscribed cortical lesion as a hemangioma, not cancer.
Implications:
- This case underscores the potential for renal cortical hemangiomas to radiologically mimic renal cell carcinoma.
- Accurate preoperative diagnosis and differentiation are essential to avoid unnecessary radical surgeries.
