Case adapted management is required in the rare occasion of a T1a parenchymal tumour in a crossed fused renal ectopia (CFRE). According to guidelines, a partial nephrectomy is the primary treatment method. However, the anatomical complexity of the tumour and also of the anomaly itself can reduce the surgical safety and efficacy of a partial nephrectomy. A patient with CFRE bearing a solid mass of 41 mm diameter was treated by using computed tomography (CT) guided percutaneous cryoablation.
