T2- weighted fat saturated axial (a) and coronal (b) MR image demonstrating a soft tissue sarcoma (malignant hemangiopericytoma) in the thigh of a 10-year-old male. A pre-resection embolization was requested due to its hypervascularity and risk of bleeding during surgery. c Pre-operative angiography demonstrating arterial tumor blush from branches of the superficial and deep femoral arteries (arrows). These feeders were embolized with 70–150 DC bead LUMI to reduce bleeding during resection. d Axial cone beam CT image obtained post embolization demonstrating the radio-opaque embolization beads in the tumor bed (arrows). e Post embolization angiography demonstrating disappearance of the arterial tumor blush
