a patient, the Bosniak classification system has been shown to be reliably applicable to contrast enhanced MRI [4]. Type 1 Bosniak type 1 renal cysts are simple benign cysts. They characteristically have hairline thin walls, do not contain any septa and do not enhance [4,5]. They do not contain solid components or any calcification [4,5].

An important note is that the Bosniak classification (version 2019) is a proposed update that has had some small validation studies with mixed results 2-4 and its use in clinical practice is not widespread (c. 2021). Classification. The new version has separate CT and MRI criteria: CT. Class I . well-defined thin (≤2 mm) smooth wall

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. 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. This diagram depicts various renal cysts morphologies, listed in order by their potential for malignancy, using the Bosniak classification system.
