Radiological imaging plays a crucial role in the detection, characterization, treatment planning and follow-up of kidney tumors. With the increasing utilization of imaging techniques, a significant number of kidney tumors are now incidentally discovered. As radiologists, our primary objective is to accurately differentiate between benign and malignant tumors, thereby guiding appropriate treatment strategies. Various imaging modalities can be employed for this purpose, each possessing unique advantages and limitations in different clinical scenarios. This paper aims to discuss common renal masses and explore the available imaging modalities used for their differentiation.
