Overview
Abdonimal CT scan is helpful in the diagnosis of renal oncocytoma.[1]
CT
On abdominal CT scan, renal oncocytoma is characterized by a large well demarcated tumor.[1]
Non contrast
- Homogenous attenuation: If tumor size is less than 3 cm
- Heterogenous attenuation: If tumor size is more than 3 cm
- Perinephric fat-stranding may be present due to edema
- 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
- Renal vein thrombosis may be present, but tumor thrombus is absent
