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. The cysts in the top row (1 and 2) do not need further evaluation or monitoring. The cysts in the bottom row (2F, 3 and 4) should be followed (the "F" in 2F means it requires "followup") and require The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT.

It measures less than 3 cm and does not have any imaging worrisome features, in keeping with a Bosniak 2 category. No further imaging is required. The Bosniak classification system for CT evaluation of renal cysts is helpful in determining both malignant risk and required follow up / treatment. From the case: Bosniak renal cyst - type IIF. CT.

Royal United Hospital, Bath, UK. Search for more papers by this author. Jonathan McFarlane. The Bosniak renal cyst classification has, thus far, passed the test of time and has been a useful method for diagnosing and suggesting the management of complicated cysts and cystic neoplasms. In the past 25 years, there have been continuous advances in the diagnosis of disease throughout the body owing to the introduction of new technology and the experience gained with its use. In 1986 Bosniak proposed a simple, four category classification system for renal cysts, which has since been widely adopted and has been proven to be sound and reliable[1,2]. It's main purpose was to distinguish between cysts that were likely to be malignant and thus required surgical intervention, and those that were almost certainly benign and thus Bosniak IIF masses have been followed, and Bosniak III and IV masses historically have been treated unless sub-stantial comorbidities or limited life expectancy would warrant observation instead (10–12). Rationale for Updating the Bosniak Classification The Bosniak classification has withstood the test of time May 23, 2016 - The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. It is helpful in predicting a risk of malignancy and suggesting either follow up o 2017-07-01 · In 1986 Bosniak proposed a classification of renal cysts, distinguishing categories from I to IV. The diagnosis and management of complex renal cysts were contentious, and a combination of CT, ultrasound and urography was used to distinguish between benign and malignant cystic renal lesions.

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 Diagram - Bosniak classification of renal cysts pinimg.com.

When facing such a lesion, the question which needs to be answered is whether this lesion is surgical or not. A study has suggested that a homogeneous mass measuring 70 HU or greater at unenhanced CT has a greater than 99.9% chance of representing a high-attenuation renal cyst. This is classified as a Bosniak type 2 cyst.
