5 yrs ago a CT scan showed a Bosniak 3 cyst , an undertimined cyst with enhancement. The Urolgist after doing an MRI decided that it was a simple cyst. Last month a CT scan was done for a stomach problem and of that cyst showed again as complex cyst. Pretty much the same except it grew from 2.2 cm to 3 cm still enhancing and still classified as a undetermined cyst, Bosniak 3 still.

These lesions are classified using the Bosniak system, which comprises four main categories: Bosniak 1, 2, 3, and 4. 2,3 Contrast-enhanced ultrasound (CEUS) can be used to characterize simple and complicated cystic lesions and can provide information on kidney vascularity and perfusion.

While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% (2), reported malignancy rates range from 31% (3) to 100% (4). III These lesions are indeterminate cystic masses that have thickened irregular walls or septa in which enhancement can be seen. IV These lesions are clearly malignant cystic lesions that contain enhancing soft-tissue components. TABLE 2 The amount of cystic calciﬁcation as a predictor of malignancy [14] Bosniak category N lesions Mean Ca score The two uncategorizable lesions had a mean enhancement of 26.8 H. CONCLUSION: The results of our study serve to underscore some limitations of the Bosniak classification system because most of our category II and all of our category III lesions were malignant, suggesting that minimally complex cystic renal masses may contain malignant cells. 2017-03-16 · tinguish cystic lesions from solid renal masses with necrotic components, which behave more aggressively.3 Hence, the characterization of these cystic renal masses is crucial to determine the best clinical approach to be adopted. We reviewed the literature with the aim to offer guidance to physicians managing cystic renal lesions and to standardize Keywords: Bosniak, Cystic renal lesion, Cystic renal cell carcinoma, CT, MR Key points Cystic renal lesions are a common incidental finding on routinely imaging examinations.

Smith and E. Remer and Kelly L Cox and M. Lieber and B. Allen and S. Shah and B. Herts}, journal={Radiology}, year={2012}, volume={262 1 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. One-hundred-and-twelve out of 364 patients with Bosniak 2F lesions … 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.

A small group of Bosniak IIF renal cysts are difficult to screen, an attribute linked to increased malignancy in surgical morphology. 4,10,18 Several findings suggest that Bosnian Class III lesions are “surgical lesions" because the rate of carcinoma is around 50%.

Treatment: Bosniak lesions in category I are benign cysts and do not require further imaging or Nov 30, 2019 Contrast-enhanced CT images of Bosniak classification of cystic Bosniak category IIF and III cystic renal lesions: outcomes and associations. Mar 15, 2021 Bosniak category IIF and III cystic renal lesions: outcomes and associations.

Bosniak category III cystic renal lesions are indeterminate in malignant potential and most commonly managed with surgical excision. While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% , reported malignancy rates range from 31% to 100% .

2020-10-28 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). 2018-02-23 2020-01-03 A small group of Bosniak IIF renal cysts are difficult to screen, an attribute linked to increased malignancy in surgical morphology. 4,10,18 Several findings suggest that Bosnian Class III lesions are “surgical lesions" because the rate of carcinoma is around 50%. 2019-01-19 Long-term Surveillance of Complex Cystic Renal Masses & Heterogeneity of Bosniak 3 Lesions .
