Preoperative transarterial Embolisation in bone tumors

Figure 1 Pre-operative Embolisation of aneurysmal bone cyst of left pelvic bones in a 13-year-old male. A: An image from a digital subtraction angiography examination of a 13-year-old male showed an expansile lesion involving the left inferior pubic ramus and ischium with no cortical breech or extraosseous soft tissue component. The lesion proved to be an aneurysmal bone cyst on histopathology; B: Angiogram obtained after cannulation of left common iliac artery revealed marked vascularity of the lesion with multiple tumor feeders arising from both the internal and external iliac artery; C: Selective left common femoral angiogram showed the tumour supply from this artery; D: Post-Embolisation angiogram after injection of 95% alcohol selectively into the major feeder arising from both the internal and external iliac arteries showed a marked reduction in tumor blush.
