Magnetic resonance imaging (MRI) and contrast enhanced Skip to Article Content; Skip to Article Information Approximately one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and the majority (88%) of small Bosniak category 2F lesions regressed or remained stable during active surveillance. Therefore, small size should be a consideration for conservative management. the renal surface.3 Renal function is usually preserved, regardless of the cyst’s location or size. 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 A Bosniak category III lesion is an indeterminate complex cyst with an increased probability of malignancy ranging from 31 % to 100 %.

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). 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 2010-01-21 Our aim was to retrospectively evaluate the attenuation characteristics in multiphase computed tomography (CT) and to determinate the incidence of malignancy based on histological findings on all Bosniak category III renal cystic masses investigated in our department between April 3, 2007 and November 21, 2013. 2019-09-07 The malignancy rate of Bosniak III renal cysts was 40% (29/72), which is significantly lower than 90% (18/20) for surgically resected Bosniak IV renal cysts (p < 0.0001). The malignancy rate of Bosniak IIF renal cysts was 38% (3/8), which is not significantly different from the rate of malignancy of Bosniak III renal cysts (p = 1.000).
