The Bosniak Classification (Warren, & McFarlane 2005) It is usually easy to differentiate between lesions at the ends of the spectrum, i.e. the benign simple cysts (Bosniak I) and the clearly Complex renal cysts pose a substantial diagnostic and management dilemma. The Bosniak classification, introduced in 1986, established an imaging framework for differentiation of benign and malignant cystic renal lesions. 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. 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 further evaluation and management. type I: almost universally benign and appear as simple cysts on CT with extremely thin walls.
Approximately one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and the majority (88%) of small Bosniak category 2F lesions regressed or remained stable during active surveillance. Therefore, small size should be a consideration for conservative management. Overall, 27 patients with Bosniak category IIF lesions were initially managed by active surveillance, from which eighteen (67 %) did not progress after a median interval of 64 months, while 9 (33
