Imaging spectrum of renal oncocytomas: a pictorial review with pathologic correlation.

Objectives: The purpose of this pictorial review is to present the imaging spectrum of renal oncocytomas with radiological-pathological correlation.

Conclusion: The differences in tumour cellularity (high cellularity or low cellularity with abundant stroma) and haemorrhagic/cystic change contribute to a wide spectrum of imaging findings of renal oncocytomas. Imaging findings substantially overlap those of common subtypes of clear cell and non-clear cell renal cell carcinomas.
