Jan 15, 2001 Asymptomatic patients with simple renal cysts require no further evaluation. of a simple renal cyst include the following: (1) spherical or ovoid shape; (2) absence of internal Bosniak's Classification of Cyst
Abstract. Bosniak classification type 1 renal cysts (Type 1 renal cyst) are very frequent and do not warrant follow-up or specific treatment. Here, however, we report two cases of type 1 renal cysts that were diagnosed on CT, US, and gross pathology without a solid component. All two cases were later verified as cases of cystic renal cell carcinoma
Nu zijn er vijf categorieën (I, II, IIF, III en IV). Bij categorie I en II … 2019-01-19 · Bosniak I: these are simple, benign cysts with a 0-2% risk of malignancy. These cysts are hairline-thin walled, without septations, calcifications or solid components. They are the same density as water, with no enhancement with contrast. There is no need to follow these cysts.
Results: Fifteen of 25 (60%) of Bosniak III lesions were determined to be malignant. All malignant lesions were classified as either Fuhrman grade 1 or 2 with no evidence of progression to Bosniak IV. Average size of malignant lesions was smaller than those of benign pathology (3.52±1.99 cm vs. 5.66±2.53 cm; p=0.041). Morton Bosniak later indicated that BIIF cysts with mild effects should only follow-up for 1–2 years, whereas progressively complicated BIIF cysts could be studied for a longer period (e.g. 3–4 years or longer). 34 CT has the best level of accuracy to identify broad renal cystic volumes.

i.e. the benign simple cysts (Bosniak I) and the clearly malignant Bosniak IV lesions. Bosniak himself recognised that the difficulty lay with distinguishing Bosniak II and III lesions, and this led to the new category of Bosniak IIF which was not contained in the original Bosniak classification (Warren, & McFarlane 2005). As Warren et al state;
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 1 • simple cyst o imperceptible wall, rounded o work-up: nil o percentage malignant: ~0% Bosniak 2 • minimally complex o a few thin <1 mm septa or thin calcifications (thickness not measurable); non-enhancing high-attenuation (due to proteinaceous or haemorrhagic contents) A Bosniak I cyst is a simple cyst which has a hairline-thin wall, without calcifications, septations, or enhancement. A Bosniak II cyst is minimally complicated. It may show a few hairline-thin septa, with small or short segment calcification in the cyst wall/septa.
