2 Approximately half of all observed Bosniak 3 lesions in a series were found to be benign, and half were found to be malignant. 7,8 In benign Bosniak 2 or 3 lesions there is no enhancement within the cyst or the cyst wall. A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon.
Numerous renal cysts are seen in the cystic kidney diseases, which include polycystic kidney disease and medullary sponge kidney.

Biopsy seems to be a useful diagnostic tool prior to planning of an imaging follow The Bosniak classification separates renal masses into 1 of 5 categories: 1, simple cyst; 2, minimally complex with single thin (1‐mm) septations, a thin calcified wall, or both (well‐marginated, nonenhancing, high‐attenuation renal lesions <3 cm are also included); 2F, increased number of septa, minimally thickened or enhancing septa or wall, or thick calcifications (hyperdense cysts 2018-12-01 · The Bosniak classification of renal cyst complexity initially served to aid in differentiating nonsurgical lesions (categories 1 and 2) from surgical lesions (categories 3 and 4). 6, 7 Category 2F lesions were created later as a group to be followed to prove cyst benignity.
No patient in this study developed metastatic disease within the three-year followup period. 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. As a result, many Bosniak III masses are benign but treated (18, 19), resulting in unneeded procedural morbidity, decreased renal function, and excess health care costs (49 – 53).

It is necessary to combine MR features with CT findings in evaluation and management of these cases with renal cystic masses. 1 Introduction Bosniak 1 and 2 lesions are likely to be benign whereas Bosniak 3 and 4 lesions are more likely to be cancerous. What makes a growth on the kidney suspicious is when it appears to be solid on the imaging and when it "picks up" the dye that is used during CT or MRI scans (we call this enhancement).
1 Apr 2012 Although the most frequently encountered form of renal cystic lesion is evaluation are cystic lesions belonging to Bosniak1 categories III and
Bosniak category III cystic renal lesions are indeterminate in malignant potential and most commonly managed with surgical excision. While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% ( 2 ), reported malignancy rates range from 31% ( 3) to 100% ( 4 ). To classify a renal cyst as type I, there must be no septa, calcifications, or solid components. These lesions do not enhance with IV contrast. type 2: almost universally benign, but unlike type I, they may contain thin septa.
The Bosniak classification for Renal Cysts was developed in late 1980s for management of complex Cystic Renal Lesions. Bosniak classification system has also been utilized with some advantages for magnetic resonance imaging. 2017-12-18 · Bosniak classification used in the Vilnius University Hospital Santariškių Klinikos to evaluate renal cystic lesions was based on the criteria described in literature [2, 3]. Data of genetic disorders and history of malignancy were collected before or at the moment of the Bosniak category III cystic lesion discovery. 2018-04-06 · Summary of radiological and pathological findings of 25 cases of renal masses Patient # Gender Age (at surgery) Classification (on CT/MRI) 1 F 66 Bosniak III (CT) 2 F 75 Bosniak III (CT) 3 M 66 Bosniak III (CT) 4 F 41 Bosniak III (MRI) 5 F 80 Bosniak III (MRI) 6 F 37 Bosniak III (MRI/CT) 7 M 66 Bosniak III (CT) 8 F 60 Bosniak III (MRI) 9 M Bosniak III (MRI) 10 M 51 Bosniak III (CT) 11 F 66

Conclusions: The malignancy risk of Bosniak III renal lesions was 60% in our study. All Bosniak III lesions were of low Fuhrman grade with no evidence of progression. No patient in this study developed metastatic disease within the three-year followup period.
