Since then, refinements have reduced the number of benign masses in Bosniak class III (2–9). For example, Bosniak IIF (where the F The Bosniak classification categorizes renal cysts into five groups. Category I. Benign simple cyst with thin wall without septa, calcifications, or solid components, and has a density of 0–20 Hounsfield units (HU) (about equal to that of water). In such cases, a CT scan without intravenous contrast is enough for classification.

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. Bosniak classification version 2019 proposed refinements for cystic renal mass characterization and now formally incorporates MRI, which may improve concordance with CT. OBJECTIVE. The purpose of this study is to compare concordance of CT and MRI in evaluation of cystic renal masses using Bosniak classification version 2019. The Bosniak classification in these cases may even be unnecessary, as cystic lesion with a solid component will always be removed whereas a simple cyst will be followed. A subsequent study by Karmazyn et al. 13 reported moderate interobserver agreement (kappa =0.48), which improved (kappa = 0.65) when the population was divided into binary classes. This Bosniak group would remain active for several decades, with the continuity of ideas and the use of the Bosniak name.
