Imaging

Abstract

The incidence of renal cell carcinoma is rising and its represents the 2%, 3% of all cancers. The increased use of ultrasonography, contrast enhanced ultrasonography, computed tomography and magnetic resonance imaging have resulted in incidentally detected small renal masses (SRMs). SRMs represent a heterogeneous group of tumors that included metastatic lesions, benign, malignant, and cystic lesions. With the increase number of renal incidentalomas, we have seen an increase in therapeutic choices (surgery, ablation therapies and active surveillance). The role of imaging has progressively grown over the decades and became currently a cornerstone that is needed to perform diagnosis, treatment and follow-up of SRMs after ablation treatment. Hence, in this review, we critically assess recent literature on the role of imaging in the context of ablation management of SRMs with a focus on the diagnosis and follow-up protocol.
