Bosniak has suggested that for lesions with less worrisome features (meaning they are closer in resemblance to type 2 than type 3), 1-2 years of follow up with CT is sufficient [2].

While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% , reported malignancy rates range from 31% to 100% . Mean lesion size was 4.6 cm (range, 1.1–8.1 cm) for Bosniak category III lesions and 3.5 cm (range, 1.2–22.0 cm) for Bosniak category IV lesions. The mean size of malignant lesions was 4.1 cm, and that for benign lesions was 3.4 cm, with no significant statistical difference noted (p = 0.387). Although the malignancy rate in surgically excised Bosniak IIF and Bosniak III cystic renal lesions was 25% and 54%, respectively, in our study, the malignancy rate was higher in patients with a The Bosniak classification system utilizes specific CT or MR imaging features to help classify cystic renal lesions into those that are likely benign (and do not require surgical resection) from those that are likely malignant (and thus require surgical resection).
