Results. A total of 3,036 complex renal cysts were categorized into Bosniak II, IIF, III and IV. In surgical and radiological cohorts pooled estimates showed a malignancy prevalence of 0.51 (0.44, 0.58) in Bosniak III and 0.89 (0.83, 0.92) in Bosniak IV cysts, respectively.

These cysts are not attenuated, and tend to have Hounsfield units of 0-20. Bosniak II- benign, minimally complicated cysts; may have hairline-thin septa with some perceived enhancement. There may be fine calcification or areas of calcified thickening along the wall or septa. Renal cysts can be classified according to the Bosniak classification depending on their features. Type I cysts are simple cysts. Type II are the minimally complicated cysts.

The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. It can be helpful in predicting a risk of malignancy and suggesting either follow up or treatment. The risk of malignancy depends on the classification of the cyst.
There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy.
A Bosniak IIF cyst has a less than 5% chance of malignancy “F” stands for follow up and although there are no strict rules on the time frame the information from Radiopaedia (radiology reference resource) suggests that 6 months
Bosniak Classification & Renal Cystic Disease 1. Bosniak Classification & Renal Cystic Disease By / Shehab Emad Resident Doctor at Urology Department Qena University Hospital 2. Introduction Renal cysts are a common finding on routine radiological studies. 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. A Bosniak IIF cyst has a less than 5% chance of malignancy “F” stands for follow up and although there are no strict rules on the time frame the information from Radiopaedia (radiology reference resource) suggests that 6 months
The Bosniak classification was described in 1986. This classification helps the radiologist to categorize each cystic renal mass as "nonsurgical" (ie, benign in category 1 and 2) or as "surgical" (ie, requiring surgery in category 3 and 4).
