In the past, renal cyst masses were either classified as simple cysts or complicated cysts. In 1986, 1 Bosniak classifications were adopted and revised many times, most significantly in 2005. 2 It was used as an effective method to determine renal cystic masses. It has been widely recognized and used by various radiologists and urologists, based on general agreement between experts for a long

Bosniak II renal cysts are slightly more complex. Management is essentially the same as for Bosniak I renal cyst. Bosniak IIF renal cysts is an intermediate class of

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). 2019-09-07 Bosniak 2F Renal Cysts The Bosniak system is used to classify cystic renal masses seen on imaging, and the classification is shown in the table below.

Grounded by malignancy rates, the literature supports discharge of Bosniak I and II cysts, imaging follow-up of Bosniak IIF cysts and surgical intervention for Bosniak III and IV cysts.

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. 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 Grounded by malignancy rates, the literature supports discharge of Bosniak I and II cysts, imaging follow-up of Bosniak IIF cysts and surgical intervention for Bosniak III and IV cysts. 2020-12-14 Bosniak 3 lesions can be hyperdense when imaged using computed tomography (CT). 2 Approximately half of all observed Bosniak 3 lesions in a series were found to be benign, and half were found to be malignant. 7,8 In benign Bosniak 2 or 3 lesions there is no enhancement within the cyst or the cyst wall.

Bosniak criteria Jun 12, 2018 Though Bosniak classification for renal cysts is used worldwide and Bosniak III cysts still have almost a 1:1 chance of being malignant. So the Feb 20, 2017 Bosniak 1 – simple cyst. Bosniak 2 – minimally complex cyst less than 3 cm, with a few thin septa.

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). Bosniak category III This category encompasses a variety of cystic lesions whose 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. In the past, renal cyst masses were either classified as simple cysts or complicated cysts. In 1986, 1 Bosniak classifications were adopted and revised many times, most significantly in 2005.

Category 1 and 2 lesions (simple cysts and mildly complicated cysts, respectively) are straightforward to diagnose and are benign, not requiring additional follow-up. Category 4 lesions (typically cystic neoplasms) are also easily diagnosed as neoplastic and require surgery.
