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.

Ytterligare metoder: Cystography, excretory urography, renal angiography, MR, En njurecyst kan vara enkel (I Bosniak) och komplex (II, IIF, III och IV Bosniak).

2017-03-16 · Bosniak classification – Introduction Renal cysts can be easily identified using standard med-ical imaging and, in most cases, a histological diagnosis is not required. However, lesions that are more complex may require a more detailed characterization to allow for determination of differential diagnoses and subsequent management approach. The Bosniak renal cyst classification was initially described

The malignancy rate of Bosniak III renal cysts was 40% (29/72), which is significantly lower than 90% (18/20) for surgically resected Bosniak IV renal cysts (p < 0.0001). The malignancy rate of Bosniak IIF renal cysts was 38% (3/8), which is not significantly different from the rate of malignancy of Bosniak III renal cysts (p = 1.000). The Bosniak classification for Renal Cysts was developed in late 1980s for management of complex Cystic Renal Lesions.

När ett sådant barn föds har nästan hela renal parenkym ersatts av fibrös vävnad och cyster.

A renal cyst is a fluid collection in or on the kidney.

På grund av förändring i renal parenchyma försämras njurfunktionen, vilket leder till att Endast ibland registrerade cystisk lesion av båda organen som avlägsnar urin. Njurcyster är enkla (I Bosniak) och komplexa (II, IIF, III och IV Bosniak). Medfödd cyst utvecklas på grund av mutationer, och som en följd, renal tubulär fusion. Njurcyster är enkla (I Bosniak) och komplexa (II, IIF, III och IV Bosniak).

Bosniak 3 lesions can be hyperdense when imaged using computed tomography (CT). 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.

Bosniak IIF lesions vary in appearance: (1) BIIF lesions with minimal findings close to category II in complexity and (2) BIIF lesions that are closer to category III in complexity. M.A. Bosniak has recently suggested that BIIF cysts with minimal findings only need follow-up for 1–2-years, whereas more complex BIIF cysts should be followed for a longer period (e.g., 3–4 years or longer) [ 1 ].

2020-01-03 · Cystic renal lesions are a common incidental finding on routinely imaging examinations. Although a benign simple cyst is usually easy to recognize, the same is not true for complex and multifocal cystic renal lesions, whose differential diagnosis includes both neoplastic and non-neoplastic conditions. In this review, we will show a series of cases in order to provide tips to identify benign Israel GM, Bosniak MA. An update of the Bosniak renal cyst classification system.

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. Smaller (<4 cm) Bosniak III cysts were more likely to be malignant and lesion size should be taken into consideration when considering management of complex cysts.

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 Bosniak was the normal radiological assessment procedure for cystic renal lesions. Originally, it relied on computed tomography (CT) scan results and subsequently extended to magnetic resonance imaging (MRI). Renal cell carcinoma (RCC) surveillance was not enhanced in the past 20 years. In our study, one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and most (88%) of the small Bosniak category 2F lesions were downgraded or remained stable on follow-up. In none of the patients with lesions that were Bosniak category 3 or 4 at follow-up imaging did recurrent or metastatic disease develop. 2018-12-01 2020-01-24 2019-07-01 2014-05-09 2020-10-28 Bosniak Classification for Renal Cystic Disease!for more: http://radiologydefinition.com/Blog/bosniak-classification-renal-cysts/Renal cysts are a common fin 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.
