Ans. D. Renal cell carcinoma
- Most likely diagnosis for an asymptomatic complex cyst in a 65 years old male as given in CT image, which appears as exophytic mass is renal cell carcinoma.
- Renal cell carcinoma (RCC) encompasses a heterogeneous group of cancers derived from renal tubular epithelial cells.
- The classic triad of loin pain, loin mass, and haematuria are seen in renal cell carcinoma.
- CT imaging with contrast enhancement of the chest, abdomen, and pelvis is required for optimal staging.

- On CT and MRI the features are of a soft-tissue mass that is at least partly solid, often lobulated and associated with loss of the normal renal architecture in the area affected.
