A 54-year-old female patient complaining of right loin pain. Axial T2-WI of the right kidney (A) showed a lower polar cystic lesion of homogenous high SI and multiple septa. This cystic lesion showed homogenous low SI at axial T1WI (B) and showed multiple enhancing septae (thickness = 3 mm), enhancing wall (3mm) at axial corticomedullary (C), nephrographic (D), and coronal DCE-MRI images (E). By consensus, cystic lesion was initially categorized as Bosniak class III in view of the presence of an enhancing thick wall and multiple irregular enhancing thick septa, while version 2019 defines a thickening of 3 mm, and the lesion was downgraded to Bosniak class IIF. The patient underwent right radical nephrectomy, and histopathology was adult cystic nephroma
