CT scan of abdomen (a) before and (b) after intravenous iodine contrast agent administration, showing a voluminous cystic mass of 9.7 cm, with non-uniform wall thickening and heterogeneous contrast enhancement, at the lower pole of the right kidney.

The CT images showed severe hydronephrosis of the right kidney, with marked thinning of the cortical parenchyma and the presence at the lower pole, of a voluminous cystic mass of 9.7 cm, which had non-uniform wall thickening, with heterogeneous contrast enhancement (Fig. 1a and b).
(a) Axial and (b) coronal T2W MR image of the abdomen showing a 9.7 cm rounded mass, with thick wall, in the right lower kidney. The mass shows inhomogeneous content with a mix component both cystic and solid, more pronounced in its cranial and peripheral portion.

T scanner and confirmed the presence at the lower pole of the right kidney of a voluminous expansive formation of 9.7 cm; this mass appeared heterogeneously hyperintense in T1 and T2 and showed only a slight contrast enhancement in its peripheral and cranial portion (Fig. 2a and b), compatible with a complex cystic mass, with predominantly hemorrhagic content (Bosniack IIF-III). The patient underwent surgery for radical nephrectomy with open access that showed a friable yellow lesion, partially cystic (Fig. 3); it was difficult to dissociate the mass from adjacent organs because of many adhesions.
Surgical excised right kidney.
