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") 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). The Bosniak classification of cystic renal disease provides a useful guide to managing cystic renal lesions. An in-depth knowledge of the various diseases that can manifest as cystic renal disease and their associated imaging findings will allow the radiologist to provide useful information to clinicians and positively affect patient care. Each mass was categorized (Bosniak classification) first on CT images and then on MR images, and results were compared.

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. The diagnosis and management of complex renal cysts was contentious, and a combination of CT, US and urography was being used to distinguish between benign and malignant lesions.

To understand the place of CEUS in renal cyst characterisation and the follow-up. Bosniak Classification of Renal Cystic Disease The Bosniak classification was described in 1986.

2016-06-07 · Twenty-nine lesions were classified as Bosniak I, II or II-F by CT and/or MRI and 13 as Bosniak III or IV, by one of the methods. The interobserver agreement for Bosniak classification for CT was 0.87 and 0.93 for MRI. Fifteen lesions had higher Bosniak categories on MRI, included six with change in management.

Bosniak classification system: a prospective comparison of CT, contrast-enhanced US, and MR for categorizing complex renal cystic masses. Introduction.

Bosniak classification version 2019 proposed refinements for cystic renal mass characterization and now formally incorporates MRI, which may improve concordance with CT. OBJECTIVE. The purpose of this study is to compare concordance of CT and MRI in evaluation of cystic renal masses using Bosniak classification version 2019. From February 2011 to June 2012, 46 complex renal cysts were prospectively evaluated by three readers. Each mass was categorized according to the Bosniak classification and CT was chosen as gold standard. Kappa was calculated for diagnostic accuracy and data was compared with pathological results. 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). From February 2011 to June 2012, 46 complex renal cysts were prospectively evaluated by three readers.

This study investigates whether the Bosniak classification of renal cysts in CEUS examinations is comparable to gold standard CT or magnetic resonance imaging (MRI). Methods: The Bosniak classification of retrospectively evaluated CEUS examinations was 2020-12-07 · CT radiomics characterizes complex cystic renal lesions By Erik L. Ridley, AuntMinnie.com staff writer December 7, 2020 A machine-learning algorithm based on CT radiomics analysis can enable better preoperative risk classification of complex cystic renal lesions than relying only on the traditional Bosniak classification criteria, according to an international multicenter study presented 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 Using Bosniak-classification 64/87 renal cysts (73.6%) were rated equal compared to CT with upgrade of four lesions (4.6%) and downgrade of 19 lesions (21.8%) by CT (Intra-class-correlation [ICC A careful helical CT abdomen focusing on the kidneys with intravenous contrast was obtained from all patients. The lesions were categorized into surgical and medical renal cystic masses using the Bosniak classification system supported by histology reports and follow up protocols for medical cases. The Bosniak classification was initially developed solely on the basis of CT findings [1, 2]. 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.

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). 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. Klassifikation: Behandling/Uppföljning: Bosniak I: Unilokulär tunnväggig: Ingen ytterligare kontroll: Bosniak II: Septa eller förkalkning: Kontroll om 6 månader, om oförändrad – ej ytterligare kontroll: Bosniak III: Septa och förkalkning el. endast väggförtjockning: Öppen biopsi/njurresektion och snabbfix: Bosniak IV 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. 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.

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 or treatment. Classification. Bosniak 1.
