Patient Data

Age: 70 years
Gender: Female

Contrast enhanced MRI showing a 2.5 cm left upper pole exophytic solid renal tumor.


CT guided renal tumor ablation procedure.


Contrast enhanced (portal venous phase) CT follow up performed at 3 and 6 months post ablation. No tumor growth or enhancement is demonstrated, showing good response to treatment.

Case Discussion

This case demonstrates CT-guided renal tumor ablation for a patient with a 2.5 cm solid renal tumor in a solitary kidney, with good response to treatment on follow up CT in 3 and 6 months.

Renal tumor ablation is a treatment option for T1a renal tumors, particularly where nephron-sparing treatment is a priority, performed by interventional radiologists under CT or ultrasound guidance.
