Abstract. Bosniak classification type 1 renal cysts (Type 1 renal cyst) are very frequent and do not warrant follow-up or specific treatment. Here, however, we report two cases of type 1 renal cysts that were diagnosed on CT, US, and gross pathology without a solid component. All two cases were later verified as cases of cystic renal cell carcinoma
