Bosniak refers to the calcification system of renal cortical cyst. There are five categories based on imaging characteristics on contrast-enhanced CT. It is helpful in predicting risk of malignancy and suggesting either follow-up or treatment. Bosniak 1 renal cortical cyst is characterized by imperceptible and rounded wall.

Previous studies have suggested that although malignancy rates may be >50%, mortality rates from these lesions are quite low.1,2 The objective of this study was

M.A. Bosniak has recently suggested that BIIF cysts with minimal findings only need follow-up for 1–2-years, whereas more complex BIIF cysts should be followed for a longer period (e.g., 3–4 years or longer) . This seems to be a reasonable compromise taking into consideration the high, cumulated radiation dose of repeated examinations. Simple kidney cysts are very common as people begin to age; up to half of all people 50 years of age and older have at least 1 kidney cyst. Most people have a cyst in only 1 kidney, but the number of cysts and the risk of getting cysts in the second kidney increase as we get older. Bosniak II (2) cysts are subdivided into Bosniak II and Bosniak IIF cysts According to this radiology information a Bosniak II cyst has a 0% chance of malignancy.
