title: Multicystic renal cell carcinoma.
abstract: This is a case report of a patient with cystic renal cell carcinoma that had all of the ultrasound and computed tomographic features of benign multicystic renal disease. Although this benign entity is a possibility in some patients, thick-wall cystic lesions of the kidney must be considered malignant until proven otherwise and surgery cannot be avoided.
