Fifty-six year-old male squash player has no symptoms. During routine check up exams a renal nodule is noted at ultrassonography. He undergoes magnetic ressonance imaging (MRI) for further evaluation as he has a history of allergy to iodated dye (Fig. 1 and 4).
Figures 1 and 2: MRI, T2 images, axial and coronal cuts; heterogenous mesorenal expansive lesion (arrows).
Figures 3 and 4: MRI, xial and coronal cuts, paramagnetic dye, shows mild heterogenous absorption. A well define dlesion can be seen (yellow arrow) with a necrotic central area (*) close to the collecting system. At the second frame lesion is easily delineated (red arrow).
