It has been more than 30 years since the Bosniak clas- sification of cystic renal masses was first proposed (1). This CT-based classification was introduced in 1986 and originally divided cystic renal masses into one of four

The Bosniak classification categorizes renal cysts into five groups. Category I. Benign simple cyst with thin wall without septa, calcifications, or solid components, and has a density of 0–20 Hounsfield units (HU) (about equal to that of water). Renal cysts can be classified according to the Bosniak classification depending on their features. Type I cysts are simple cysts.

However, for the most part, sonography and CT (or a combination of these when necessary) have become the main diagnostic techniques for evaluating renal masses, and with their use we have never been more accurate, noninvasive, and relatively economically efficient. The Bosniak renal cyst classification was introduced in 1986. This classification was based on computed tomography (CT).

C, Axial contrast-enhanced fat-saturated T1-weighted MR image shows enhancing convex protrusion with obtuse margins ( arrowhead ) measuring 5 mm along posterior aspect of mass. 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).

Type I and II can be ignored. Type II F are probably benign, but need to be followed. Type III and IV both are surgical lesions.
