Angiographic and volumetric effects of mammalian target of rapamycin inhibitors on angiomyolipomas in tuberous sclerosis

Figure 4 Volumetric analysis of patient 3 angiomyolipoma. A left renal AML was treated with two embolization procedures prior to mTOR inhibitor therapy. Reduction in tumor volume with mTOR inhibitor affected both the soft tissue and vascular components of the tumor. However, discontinuation resulted in rebound growth, including tumor vascularity. AML: Angiomyolipoma; mTOR: Mammalian target of rapamycin.
