Het betreft dan meestal cysteuze niercelcarcinomen, die klinisch milder verlopen dan solide tumoren. In onze ogen zijn er goede argumenten om bij Bosniak III-cysten < 4 cm surveillance toe te passen, net zoals tot nu toe gebruikelijk is bij Bosniak IIF. 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. Microsimulation model of CT versus MRI surveillance of Bosniak IIF renal cystic lesions: should effects of radiation exposure affect selection of imaging strategy?
Urol Nephrol Open Access J. 2020;8(1):10‒13. DOI: 10.15406/unoaj.2020.08.00266 Figure 1 Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) flow diagram. Surveillance of bosniak IIF renal cysts 2017-06-01 · We analysed 35 Bosniak II, 34 Bosniak IIF, 58 Bosniak III, and 61 Bosniak IV lesions. The overall incidence of renal cell carcinoma was 8.6%, 29.4%, 62.1%, and 78.7% for each category. Based on our surveillance strategy of Bosniak IIF masses, we recommend computed tomography (CT)/magnetic resonance imaging (MRI) every 2 years after the initial examination. Se hela listan på pubs.rsna.org Adding the IIF category has increased the accuracy and clinical impact of the Bosniak categorization system, as evidenced by a low rate of progression in category IIF cysts and an increased rate of malignancy in surgically treated category III lesions compared to those in historical controls. Although there have been long-term surveillance studies of Bosniak category 2F lesions [26], to our knowledge ours is the largest single-institution study of active surveillance of confirmed (by 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.
Originally, it relied on computed tomography (CT) scan results and subsequently extended to magnetic resonance imaging (MRI). 2018-12-01 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.
2020-05-05 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. Radiological progression of Bosniak 2F cysts is low but may occur up to 24 months after diagnosis. Our data suggests that it is safe to discharge patients with stable cysts after 2 years of surveillance. Adhering to follow-up protocols can alleviate pressure on radiology and urology services.
The current classification contains five categories: I, II, IIF, III and IV. Categorie I and II lesions are assumed benign and do not require further treatment. A IIF lesion is possibly benign and surveillance is Postoperative pathology examination revealed a multilocular cystic renal cell carcinoma. Resection of the Bosniak 2F cyst provides 2 advantages: the recipient receives a new donor kidney and will be free of dialysis, and the donor will be free of surveillance. Purpose: We sought to better characterize the frequency of Bosniak cyst class changes, identify predictors of change and progression, determine the average growth rate of cysts and validate the safety of active surveillance.
These cysts may demonstrate an increased number of septa or minimal smooth thickening of the wall or septa. 2013-03-26 · Surveillance images of Bosniak IIF were reviewed to determine radiological progression and clinical outcomes. Results: Forty patients with 42 category IIF cysts were included in our study (median age 68 years (range 38–88 years), median follow-up of 29 months (range 5–77 months)). To better characterize the frequency of Bosniak cyst class changes and identify predictors of change and progression. To determine the average growth rate of cysts and validate the safety of active surveillance. Consecutive patients referred for management of complex cysts (>= Bosniak 2F) were included. In contrast, Bosniak 3 cysts with enhancing thickened nodules (3n) are more similar to Bosniak 4 lesions; they are more likely to progress to Bosniak 4 on subsequent imaging studies and more likely to be malignant when resected (100% of 3n vs 41% of 3s).

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.
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.

Il sistema di classificazione inserisce le cisti renali (renali) in cinque categorie, a seconda dei risultati sulla TC. Oltre a Bosniak 2F, gli altri quattro includono: Bosniak 1, Bosniak 2, Bosniak 3 e Bosniak 4. Il tipo di CLASSIFICATION DE BOSNIAK DES KYSTES ATYPIQUES DU REIN KYSTE ATYPIQUE DU REIN : Classification de BOSNIAK Classification scanographique et validée IRM (2002) Kyste type I = kyste simple Sans paroi visible en périphérie Densité hydrique 10UH Absence de réhaussement à l’injection. 2020-01-24 · Association with Bosniak category was explored. RESULTS: 121 patients (84:37 M:F) were identified with 136 renal lesions (84, 37 and 15 Bosniak category 2F, 3 and 4) and followed for 1-12.3 years (mean 3.5 years). 87% (73/84) of 2F lesions were downgraded or remained stable.
