Bosniak III and IV category renal cysts have measurable enhancement in thickened walls or septa on CT or MRI studies, and the presence of well-defined nodular soft-tissue components differentiates Bosniak IV from III renal cysts [1–3]. Slightly more than half of Bosniak III renal cysts and most Bosniak IV renal cysts are malignant at surgical pathology [1–3, 10, 11]. Cystic carcinoma was detected histologically in 8 Bosniak III cases. Partial nephrectomy was made in 7 cases and radical nephrectomy in 1 case.

Biopsies from seventeen Bosniak 3 cystic lesions were pathologically analyzed and five (29%) were found to be malignant. Conclusion: Our results reveal a considerable malignancy rate among both The Bosniak classification of cystic renal masses (version 2019), or usually simply Bosniak classification, version 2019 , is a proposed update of the classic/current Bosniak criteria. The update hopes to improve on the classification's predictive power for malignancy and minimize the number of benign lesions undergoing treatment. 2018-12-01 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).

were 72% for Bosniak category III lesions and 86% for Bosniak category IV lesions. Most malignant cysts were early-stage (pT1) cysts with low histologic grades (89% of Bosniak III lesions and 91% of Bosniak IV lesions). Follow-up studies of the surgically resected lesions did not show local recurrence, metastasis, or lymph node enlargement.

Minimal but un-measurable enhancement of the septa or cyst wall may also be appreciated. High-attenuation cysts of less than 3 cm in diameter that do not enhance are considered type II. type 2F: (the “F” is for follow-up needed) cysts are more complex that simple type II cysts, but do not meet the criteria for a type III classification.

There is uncertainty with regard to the duration of follow up imaging for these lesions. Bosniak has suggested that for lesions with less worrisome features (meaning they are closer in resemblance to type 2 than type 3), 1-2 years of follow up with CT is sufficient [2]. For lesions that appear more worrisome, 3-4 years of follow up may be
