A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy.

A Bosniak category III lesion is an indeterminate complex cyst with an increased probability of malignancy ranging from 31 % to 100 %. For these cysts, the usual workup is surgery or, in selected cases, radiological follow-up. Bosniak IV cysts have clearly malignant features and surgical therapy is recommended. La classification de Bosniak établie en 1986 et révisée en 1993 (Tableau I) [2, 3], a pour objectif de classer selon des critères morphologiques, les kystes atypiques en fonction de leur risque évolutif. Ainsi la classification de Bosniak établie 5 stades différents en fonction de l'aspect tomodensitométrique du kyste.

To classify a renal cyst as type I, there must be no septa, calcifications, or solid components. These lesions do not enhance with IV contrast. type 2: almost universally benign, but unlike type I, they may contain thin septa. Thin or slightly thickened calcification may be noted within the cyst wall.

The 35 cystic renal lesions were categorized as 15.

Conclusion. FP and SV are useful quantitative surrogates for Bosniak category and future behavior, respectively. Growth of small renal lesions by an increase in fluid volume and FP leads to a downgrade in Bosniak category. Initial SV less than 0.05 cc in Bosniak 3/4 lesions suggests possible future downgrade.

The widespread used Bosniak classification (I–IV) classifies renal lesions in five individual groups using contrast-enhanced computer tomography (CE-CT), magnetic resonance imaging (MRI) and/or contrast-enhanced ultrasound (CEUS) imaging criteria.

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 .

Abstract. Ultrasound is a common and established imaging method for the initial characterization of renal lesions. The widespread used Bosniak classification (I–IV) classifies renal lesions in five individual groups using contrast-enhanced computer tomography (CE-CT), magnetic resonance imaging (MRI) and/or contrast-enhanced ultrasound (CEUS) imaging criteria.

Careful examination of adjacent tissue is essential, as secondary cysts may form when solid tumors obstruct tubules of normal pa-renchyma. Cystic lesions containing enhanc-ing soft tissue unattached to the wall or septa likely are malignant.4 Long-Term Surveillance of Complex Cystic Renal Masses & Heterogeneity of Bosniak 3 Lesions J Urol 2018 Aug 01;[EPub Ahead of Print], DK Pruthi, Q Liu, IDC Kirkpatrick, J Gelfond, DE Drachenberg From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine.

Growth of a cystic mass without morphologic change is not indicative of malignancy. 3A Bosniak IIF cystic renal mass without change in imaging features forat least 5 years is considered stable and likely of no clinical significance.

Bosniak Classification of Renal Cystic Disease. The Bosniak classification was described in 1986.

There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy. 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.
