The Bosniak classification system of renal cystic masses divides renal cystic into five categories based on imaging characteristics on contrast-enhanced CT.

It has been more than 30 years since the Bosniak clas-sification of cystic renal masses was first proposed (1). This CT-based classification was introduced in 1986 and originally divided cystic renal masses into one of four classes after exclusion of infectious, inflammatory, and vascular etiologies ( Table 1) (1). Since then, refinements

The cysts in the top row (1 and 2) do not need further evaluation or monitoring. Bosniak Classification of Renal Cystic Disease 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). n The updated Bosniak classification of cystic renal masses (Bosniak Classification, version 2019) aims to improve the original classifi-cation’s ability to predict the likelihood of malignancy in a cystic renal mass. n The principal goals of the update are to (a) address data indicat-ing renal cell carcinoma with predominant cystic change is The original Bosniak classification system is based on CT features , and studies of CT evaluation are far more common than MRI studies . We deliberately chose to study MRI because version 2019 formally incorporates this modality into the diagnostic criteria, and we thus anticipate the use of MRI to characterize cystic renal masses to increase. Bosniak classification version 2019 proposed refinements for cystic renal mass characterization and now formally incorporates MRI, which may improve concordance with CT. OBJECTIVE.

Magnetic resonance (MR) and contrast-enhanced ultrasonography (CEUS) imaging may demonstrate findings that are not depicted at CT, and there may not always be a clear correlation between the findings at MR and CEUS imaging and those at CT. Objective To systematically review the literature on the Bosniak classification system in CT to determine its diagnostic performance to diagnose malignant cystic lesions and the prevalence of malignancy in Bosniak categories. Methods A predefined database search was performed from 1 January 1986 to 18 January 2016. Two independent reviewers extracted data on malignancy rates in Bosniak THE ORIGINAL BOSNIAK CLASSIFICATION OF RENAL CYSTS In 1986, Bosniak [8] proposed a classification of renal cysts.

Subsequently, a few studies have suggested that MR [ 31 , 40 ] and CEUS [ 4 , 8 , 41 – 46 ] may be equally useful for characterisation of complex renal cystic masses. CT surveillance showed increased cyst size in the left kidney with cystic changes, however, the Bosniak classification remained the same. It was not until the patient deteriorated further that an 2020-12-07 What is the bosniak classification? In 1986 Bosniak proposed a classification to characterize cystic kidney masses detected by CT scan as “nonsurgical” (i.e., benign) or “surgical” (i.e., requiring surgery). In his original classification, there were four categories: • … Because of such a necessity, Bosniak, in 1986 , developed a classification system based on computed tomography (CT) imaging criteria allowing for the analysis of renal cysts' contour and contents, presence of septations and/or calcifications, and enhancement after contrast agent injection.

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.23656 Justin Ruey Tse, MD and 2018-04-01 · The Morton Bosniak classification system is the central tool for diagnosing renal cystic masses using CT for the three last decades. It is comprised of five lesion categories. These categories are used to predict the risk of malignancy as well as standardize the management of cystic renal lesions. Diagnosis of a simple cyst Because of such a necessity, Bosniak, in 1986 , developed a classification system based on computed tomography (CT) imaging criteria allowing for the analysis of renal cysts' contour and contents, presence of septations and/or calcifications, and enhancement after contrast agent injection.

Bosniak Class I – No follow up is generally required since there are no identified radiologic criteria of malignancy. Bosniak Class II – No follow up is generally required since there are no identified radiologic criteria of malignancy. Bosniak Class II F – This lesion is likely benign, but follow up imaging is suggested.
