The Bosniak classification is widely used by radiologists and urologists for addressing the clinical problem assessing renal cysts 3. It was last updated in 2005 12 . A Bosniak classification, version 2019 11 has been proposed to increase the accuracy and include MRI features but does not yet (c. 2021) have widespread validation.

No se aprecia realce significativo de contraste en la lesión de riñón derecho, que además permaneción estable durante 3 años. Therefore, accurate differentiation between the two lesions is crucial. Bosniak staging governs the decision to operate on CRCs [2, 3]. This classification of renal cystic lesions was produced in an attempt to standardize the evaluation of the condition across all imaging modalities.

Barr et al. indicated that Bosniak III lesions that do not show CEUS contrast trapping can reasonably undergo follow-up. Additionally, it was reported that every lesion presenting contrast trapping on CEUS should be considered malignant until proven otherwise, and undergo biopsy and/or surgical removal, independently of its Bosniak score [ 4 ].

The mean size of malignant lesions was 4.1 cm, and that for benign lesions was 3.4 cm, with no significant statistical difference noted ( p = 0.387).

87% (73/84) of 2F lesions were downgraded or remained stable. 48% (25/52) of 3/4 lesions were downgraded. 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 definition of “cystic” in imaging is a mass which has a mostly fluid-filled spaces more than one-fourth of the lesion. 1 Cystic renal mass account for nearly 15% of all renal mass lesions.

Lesion size was significantly lower for malignant cysts compared to benign ones in the patients with Bosniak 3 lesions (44.2 ± 27.5 vs 80 ± 55.9 P= .005). In the subgroups,

The update hopes to improve on the classification's predictive power for malignancy and minimize the number of benign lesions undergoing treatment. 2010-08-19 · Bosniak 3 confusion. Von55. Posts: 57. Joined: Aug 2010.
