true malignancy risk. If all conservatively managed Bosniak IIF cysts were benign, the risk of malignancy would approach 8%; therefore, the true malignancy rate of Bosniak category IIF cysts likely falls somewhere between 8 and 27% (Table 2).

A Bosniak I cyst is a simple cyst which has a hairline-thin wall, without calcifications, septations, or enhancement. A Bosniak II cyst is minimally complicated. It may show a few hairline-thin septa, with small or short segment calcification in the cyst wall/septa. Perceived (as opposed to measurable) enhancement is sometimes present.

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). 2021-02-10 2019-01-10 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.

The qualitative features of Bosniak III cystic masses are similar between the current classification and the proposed update (Tables 1, 2): cystic masses with one or more thick or irregular (ie, not smooth) enhancing walls or septa without nodular enhancement.

They can be classified as either simple or complex.

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.
