Background
Renal cysts are very common in adults since approximately 50% of patients aged >50 years have at least one. Moreover, their detection is very frequent in clinical practice because of the increasing use of imaging modalities.
While simple cysts are fully characterized with ultrasound (US), other lesions require further characterization, which is traditionally obtained by multiphase imaging, such as contrast-enhanced Computer Tomography (CECT) and Magnetic Resonance (MRI). Contrast-enhanced ultrasound (CEUS) has been proved to be a useful imaging modality to characterize complex renal cysts using the Bosniak classification in a similar way as CT. In addition to that, CEUS also plays an important role in the evaluation of indeterminate cystic lesions on CT or MRI. With its lack of nephrotoxicity, the absence of ionizing radiation, and the ability to evaluate the enhancement pattern of renal lesions quickly and in real-time, CEUS has unique advantages over traditional modes.
