Overview
CT scan may be helpful in the diagnosis of renal oncocytoma.
CT
Generally tend be large well demarcated tumors at presentation.
Non contrast
- If less than 3 cm - homogenous attenuation
- If more than 3 cm - heterogenous attenuation
- Perinephric fat-stranding may be present due to oedema
- Calcification may be present
Post contrast
- Small tumors may enhance homogeneously, but usually enhancement is heterogenous and the mass is larger
- Central stellate non-enhancing scar is seen in approximately a third of cases 4
- Renal vein thrombosis may be present, but tumour thrombus is absent
