A 63-year-old female patient presented with mild left loin pain. She was diagnosed with huge left renal AML and underwent prophylactic SAE using 3 microcoils. She suffered from post-embolization syndrome (PES); pain and fever few days after SAE that were treated with conservative treatment. On follow-up visits, there was a tumor size reduction of about (16%) 6 months after SAE. Digital subtraction angiography (a, b); a Pre-embolization angiography of the left renal artery using cobra catheter showing single renal artery with early pre-hilar division and its lower division supplying large lesion with multiple abnormal tortuous vascularities. b Post-embolization control angiogram showing no further opacification of the lesion after SAE using 3 microcoils. c T2-W (coronal image) d T2-W (axial image) and e Gadolinium-enhanced T1-W fat-saturated (axial image) MRI sequences before SAE. Huge left renal parenchymal fat-containing lesion (AML). f T2-W (axial image) MRI sequence 6 months after SAE. Tumor size reduction of about (16%)
