a) Non-enhanced CT evidencing multiple small masses with fat attenuation in the right kidney lower pole consistent with AMLs (arrow). Hyperattenuating material filling the dilated renal pelvis and calyces due to hematuria (arrowhead). b) Maximum intensity projection arterial phase CT evidencing pseudo-aneurysms/intrarenal aneurysms in the right kidney lower pole (arrows) and bilateral cortical cysts (arrowhead). c) Coronal T2-weighted fat-suppressed magnetic resonance image shows multiple bilateral simple cysts with thin regular walls (arrows). Renal parenchyma is shown in the lower pole of the right kidney (arrowhead).

ADPKD, small fat-containing masses in the lower pole of the right kidney consistent with AMLs and hyper-attenuating material filling the right renal pelvis due to bleeding (Figure 1). Arterial phase evidenced multiple saccular dilatations within the inferior interlobar branches of the right renal artery, suggestive of aneurysms/pseudoaneurysms (Figure 2A).
A: Arterial phase evidenced multiple saccular dilatations (aneurysms) within the inferior interlobar branches of the right renal artery (white arrow). B: Selective arteriography of the lower pole branch with multiple saccular dilations (White arrow). C: Cone beam CT was performed to assess the remaining kidney segments. In the reconstruction, a suspicious area of active bleeding was identified in the lower pole (white arrow). D: Superselective embolization of microaneurysms with Onix-18 and control arteriography with devascularization of the lower pole branches (white arrow).

ADPKD, small fat-containing masses in the lower pole of the right kidney consistent with AMLs and hyper-attenuating material filling the right renal pelvis due to bleeding (Figure 1). Arterial phase evidenced multiple saccular dilatations within the inferior interlobar branches of the right renal artery, suggestive of aneurysms/pseudoaneurysms (Figure 2A). Cobra catheter in which multiple microaneurysms were identified in the lower pole without signs of macrofistulas or blush (Figure 2B). Cone beam CT was performed to assess the remaining kidney segments. In the reconstruction, a suspicious area of active bleeding was identified in the lower pole (Figure 2C). Superselective embolization was performed with Onix-18 (Covidien) (Figure 2D).
