La classification de Bosniak établie en 1986 et révisée en 1993 (Tableau I) [2, 3], a pour objectif de classer selon des critères morphologiques, les kystes atypiques en fonction de leur risque évolutif. Ainsi la classification de Bosniak établie 5 stades différents en fonction de l'aspect tomodensitométrique du kyste.

Density of their contents has water's one [−10 to 20 HU] and do not enhance with contrast material. Type 1 renal cysts are known to be benign and neither surgery nor follow-up is required . Scroll Stack. This diagram depicts various renal cysts morphologies, listed in order by their potential for malignancy, using the Bosniak classification system.

The Bosniak classification is a CT-established classification initially conceived in 1986, with Bosniak 1+2 being benign and Bosniak 4 regarded as malignant.1 It

Bosniak classification of renal cysts is a radiologic classification system for kidney cysts. It originally consisted of four categories (I, II, III, IV). [1] [2] Figure 1. Bosniak classification system. Drawing courtesy of Dr. M - "Bosniak Classification for Complex Renal Cysts Reevaluated: A Systematic Review" THE BOSNIAK CLASSIFICATION Several studies have examined the reliability of the Bosniak classiﬁcation (Table 3) [5,15–21,23].

The Bosniak renal cyst classification was introduced in 1986. This classification was based on computed tomography (CT). In the course of years several adjustments were proposed.

T he Bosniak classification of cys-tic renal masses, introduced in 1986 [1], stratifies the probability of malignancy on the basis of imaging characteristics and guides clinical management. Bosniak I and II masses are be-nign and do not require follow-up. Bosniak IIF masses have a low but nonzero probabil-ity of malignancy and are followed with im-

The Bosniak renal cyst classification system was initially reported in 1986, using CT scan findings. the Bosniak classification has been widely adopted and accepted because it addresses a difficult clinical problem and is easy to apply by both radiologists and Urologists.
