In 1986, Bosniak proposed a classification system designed to separate cystic renal masses into surgical and nonsurgical categories by analysis of specific CT features. He elaborated further on this topic in later publications and commentary [ 2 , 3 , 4 ].

It originally consisted of four categories (I, II, III, IV). A subsequent modification turned it into a five category system: Category Percent malignant Management Radiological Characteristics Bosniak I 0% no follow-up necessary Simple cyst Slightly atypical upper pole cyst consistent with a Bosniak type 2F cyst. 1 article features images from this case Bosniak classification system of renal cystic masses The two uncategorizable lesions had a mean enhancement of 26.8 H. CONCLUSION: The results of our study serve to underscore some limitations of the Bosniak classification system because most of our category II and all of our category III lesions were malignant, suggesting that minimally complex cystic renal masses may contain malignant cells. 2018-08-01 Utility of the Bosniak Classification System for Cystic Renal Masses in Pediatric Patients, SSM19-04, 9011704, Mantosh Rattan, In 1986, Bosniak proposed a classification system designed to separate cystic renal masses into surgical and nonsurgical categories by analysis of specific CT features. He elaborated further on this topic in later publications and commentary [ 2 , 3 , 4 ]. • The Bosniak system is used to classify cystic renal masses seen on imaging • Only a few studies have correlated cyst classification using the Bosniak system with histological findings after removal of kidneys at surgery. Thus there is a lack of evidence to support the classification’s ability to 1996-07-01 While the Bosniak classification was originally developed for contrast-enhanced CT, the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) proposed a CEUS-adapted Bosniak categorization system in 2020 in order to overcome differences in imaging specifics and improve the diagnostic accuracy of CEUS in characterizing cystic renal lesions .

Notably, overall lesion size is no longer incorporated as a criterion. Smaller lesion size may suggest more indolent behavior [ 14 – 16 ], and in our study, RCCs with necrosis were larger than those without. The Bosniak classification system utilizes specific CT or MR imaging features to help classify cystic renal lesions into those that are likely benign (and do not require surgical resection) from those that are likely malignant (and thus require surgical resection).

Crossref, Medline, Google Scholar This diagram depicts various renal cysts morphologies, listed in order by their potential for malignancy, using the Bosniak classification system. The cysts in the top row (1 and 2) do not need further evaluation or monitoring. This is especially true for cystic masses, which compared with solid masses are more likely to be benign and, when malignant, less aggressive. For more than 30 years, the Bosniak classification has been used to stratify the risk of malignancy in cystic renal masses.

Jonathan McFarlane. 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 Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanc 1.
