Post-embolisation status in a 53-year-old man with acute haemorrhage after L-PN. Selective embolisation of arterial branches with Embozene particles and metallic coils achieved bleeding control and prompt clinical improvement. Five days later, unenhanced (a), corticomedullary (b) and nephrographic (c) phase multidetector CT acquisitions showed strongly hyperdense coils at the renal sinus causing beam-hardening artefacts, some residual peri-renal blood (*) without persistence of active bleeding, and a wedge-shaped non-enhancing parenchymal area (arrows) consistent with focal infarction. Excretory (d) phase images excluded urine leak from the collecting system
