Ultrasound findings: transaxial (a) and long axis (b) views show the right kidney containing a solid, heterogeneous isoechoic mass in the midpole. CT abdomen without IV contrasts coronal (c) and axial (d) views, respectively: a solid isodense mass of the mid to inferior pole of the right kidney protrudes into the renal sinus. There is minimal deformity of the renal contour by the lesion. An incidental cystic lesion of the liver is seen.
