The Bosniak classification of cystic renal masses (version 2019), or usually simply Bosniak classification, version 2019, is a proposed update of the classic/current Bosniak criteria. The update hopes to improve on the classification's predictive power for malignancy and minimize the number of benign lesions undergoing treatment.

Die Computertomographie ist das wichtigste Diagnoseverfahren zur Einordnung zystischer Nierenveränderungen, auch dadurch bedingt, dass die Bosniak-Klassifikation auf CT-Befunden basiert. Es ist bei einem suspektem Sonographiebefund indiziert, z.B. bei Septierung, Zystencluster, Wandverstärkung oder Verkalkung sowie echogenem Inhalt der Zyste. The purpose of this review is to describe the potential sources of variability or discrepancy in interpretation of cystic renal masses under the Bosniak v2019 classification system. Strategies to avoid these pitfalls and clinical examples of diagnostic approaches are also presented. Potential pitfalls in the application of Bosniak v2019 are divided into three categories: interpretative For more than 30 years, the Bosniak classification has been used to stratify the risk of malignancy in cystic renal masses. Although it is widely used and still effective, the classification does not formally incorporate masses identified at MRI or US or masses that are incompletely characterized but are highly likely to be benign, and it is affected by interreader variability and variable Bosniak classification of renal cystic masses has five cathegories.

Although it is widely used and still effective, the classification does not formally incorporate masses identified at MRI or US or masses that are incompletely The Bosniak classification of cystic renal masses, introduced in 1986 [ 1 ], stratifies the probability of malignancy on the basis of imaging characteristics and guides clinical management. Bosniak I and II masses are benign and do not require follow-up. This diagram depicts various renal cysts morphologies, listed in order by their potential for malignancy, using the Bosniak classification system.

The Bosniak classification for renal cysts was developed in the 1980s as an attempt to standardize the description and management of complex renal lesions. Based on classification of the renal lesion, the likelihood of malignancy can also be predicted.

It was last updated in 2005 12 . A Bosniak classification, version 2019 11 has been proposed to increase the accuracy and include MRI features but does not yet (c. 2021) have widespread validation.

Kategorie I: Unkomplizierte Zyste. Kategorie II: Zyste kleiner 3 cm zum Teil mit dünnen (< 1mm) Septen oder Verkalkungen ohne Kontrastmittelaufnahme im CT oder MRT. Kategorie IIF: Minimal komplizierte Zysten die nicht sicher in Kategorie II fallen. Bosniak Classification and Recommendations (multiphasic CT/MR): Bosniak 1 – hairline-thin wall; no septa, calcifications, or solid components; water attenuation/signal intensity; no enhancement – no further imaging follow-up is required. The classification of renal cystic lesions suggested 25 years ago, now referred to as the Bosniak renal cyst classification, remains pertinent to the diagnosis and management of these difficult-to The Bosniak Classification is used to quantify the risk of malignancy and need for observation or radical treatment based on the findings of computed tomography (CT). The case described is that of a 65-year-old man with renal cystic disease who was initially given a Bosniak stage IIF classification and was subsequently managed with CT surveillance. Using the Bosniak IIF method, the precision of downgrading lesions were shown in the classification system, which were not complicated enough to be graded as category III, but complexed than category II lesions.

T he Bosniak classification of cys-tic renal masses, introduced in 1986 [1], stratifies the probability of malignancy on the basis of imaging characteristics and guides clinical management. Bosniak I and II masses are be-nign and do not require follow-up. Bosniak IIF masses have a low but nonzero probabil-ity of malignancy and are followed with im- 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). Bosniak Classification System for Cystic Renal Lesions Using Bosniak classification version 2019, cystic renal masses were classified into 12 category I, 19 category II, 13 category IIF, four category III, and 20 category IV by CT and eight category I, 15 category II, 23 category IIF, nine category III, and 13 category IV by MRI. For more than 30 years, the Bosniak classification has been used to stratify the risk of malignancy in cystic renal masses.
