Microsimulation model of CT versus MRI surveillance of Bosniak IIF renal cystic lesions: should effects of radiation exposure affect selection of imaging strategy? Kang SK(1), Turan EA, Eisenberg JD, Lee PA, Kong CY, Pandharipande PV. Author information: (1)1 Department of Radiology, NYU Langone Medical Center, 550 First Ave, New York, NY 10016.
Objective: The purpose of this study was to determine the percentage of small (< 4 cm) Bosniak category 2F, 3, and 4 lesions that regress during active surveillance.
Presented by: Deepak Pruthi, MD, San Antonio, TX, USA Bosniak IIF renal cysts, the American College of Radiology (ACR) recommended that CT or MRI exams, should be conducted without IV contrast at 6-12 months, following diagnosis for a period of five years. The aim of imaging surveillance is to detect Bosniak IIF renal cysts that progress to higher class lesions, because higher reclassification is Radiological progression of Bosniak IIF cysts is low and progression to malignancy lower still, typically occurring within 24 months of diagnosis. Our data suggested that ceasing radiological follow-up surveillance after a minimum of two years of stable surveillance could be considered. Blue curves indicate Bosniak 2f.
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 Because many radiologists and urologists use the Bosniak classification as a management system, and because the AUA 2017 guidelines support imaging surveillance as initial management of even solid renal mass lesions smaller than 2 cm, incorporating size into the Bosniak classification makes sense, such that small cystic lesions can be managed with active surveillance regardless of Bosniak category. Active Surveillance of Small (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. cm) Bosniak category 2F, 3, and 4 lesions that regress during active surveillance.

Bosniak 2F; Kyste dont l'aspect, s'il n'est pas franchement suspect, ne permet pas de rassurer complètement. Le F signifie Follow-Up (Surveillance en anglais). Bosniak 3 (Kyste suspect) Les anomalies sont plus franches. Les cloisons ou la paroi sont plus épaisses, peuvent prendre un peu le contraste. Le contenu est plus dense.
Bosniak 2F Renal Cysts The Bosniak system is used to classify cystic renal masses seen on imaging, and the classification is shown in the table below. The Bosniak Classification (Warren, & McFarlane 2005) It is usually easy to differentiate between lesions at the ends of the spectrum, i.e.
Resectable Bosniak 2F Cyst Due to
Nov 11, 2020 Stable Bosniak IIF cysts showed a malignancy rate of less than 1% during radiological follow-up (surveillance).

Quel est le type de kyste rénal Bosniak 2F? UNE: Bosniak 2F type de kystes rénaux est une catégorie du système de classification bosniaque des masses kystiques rénales. Le système de classification classe les kystes rénaux (rénaux) en cinq catégories, en fonction des résultats du scanner. Outre Bosniak 2F, les quatre autres incluent The Bosniak renal cyst classification was introduced in 1986.
The authors conclude that septated cysts (2F and 3s) should be surveilled at 1, 3, and 5 years. Abstract: Bosniak 2F renal cystic lesions feature morphologic characteristics between Bosniak I and III categories, the majority of which remain benign.

Israel GM, Bosniak MA. Follow-up CT of moderately complex cystic lesions of the kidney (Bosniak category IIF). AJR Am J Roentgenol 2003; 181:627. Smith AD, Remer EM, Cox KL, et al. Bosniak category IIF and III cystic renal lesions: outcomes and associations. Radiology 2012; 262:152.
Materials and Methods: We retrospectively reviewed the records of patients with complex renal cysts categorized as a Bosniak IIF or III. Surveillance imaging and pathological outcomes of category IIF cysts were recorded to determine radiological predictors of progression. Bosniak Classification of Renal Cystic Disease. The Bosniak classification was described in 1986. This classification helps the radiologist to categorize each cystic renal mass as "nonsurgical" (ie, benign in category 1 and 2) or as "surgical" (ie, requiring surgery in category 3 and 4). Quel est le type de kyste rénal Bosniak 2F? UNE: Bosniak 2F type de kystes rénaux est une catégorie du système de classification bosniaque des masses kystiques rénales.
Abstract: Bosniak 2F renal cystic lesions feature morphologic characteristics between Bosniak I and III categories, the majority of which remain benign. However, a minor part of Bosniak 2F lesions may progress to malignancy. The purpose of this study was to assess Bosniak 2F cystic lesions during follow-up examinations by CEUS.
In high-volume centers with surgical expertise, Bosniak 2F cysts should be a feasible option in expanding donor criteria. 2020-05-05 · There is limited experience with imaging surveillance of Bosniak IV renal lesions.
If malignant, histology usually shows cystic renal cell carcinoma which has been reported to follow a more favourable course compared to solid tumours.
