Bosniak Classification System of Renal Cysts (Category I, II, IIF, III, IV Grading)

The Bosniak Classification System is a widely used method to categorize renal cystic masses based on their imaging characteristics, primarily from CT scans and MRIs. This system helps radiologists determine the likelihood of a cyst being benign or malignant2. Here's a brief overview of the Bosniak Classification System: Bosniak Classification Categories Class I: Description: Simple, benign cysts with thin walls (≤2 mm), no septa, and no enhancement after contrast administration. Malignancy Risk: Very low. Class II: Description: Benign cysts with thin walls (≤2 mm) and few (1-3) septa. These cysts may have calcifications and can show minimal enhancement1. Malignancy Risk: Very low. Class IIF: Description: Cysts with minimally thickened (3 mm) enhancing walls or septa. These cysts have multiple thin (≤2 mm) enhancing septa1. Malignancy Risk: Low, but higher than Class I and II. Class III: Description: Cysts with thickened (≥4 mm) enhancing walls or septa, or with irregular enhancing areas. Malignancy Risk: Moderate to high. Class IV: Description: Cysts with enhancing nodules (≥4 mm) or irregular enhancing areas with acute margins. Malignancy Risk: High. Purpose The purpose of the Bosniak Classification System is to improve the precision of diagnosing renal cysts and to reduce unnecessary surgical interventions for benign lesions #RenalCysts
