Differentiation of Sporadic Versus Tuberous Sclerosis Complex-Associated Angiomyolipoma

AJR Am J Roentgenol. 2015 Aug;205(2):292-301. doi: 10.2214/AJR.14.14255.

Abstract

Objective: We review the imaging of renal angiomyolipomas, including differentiation of tuberous sclerosis complex (TSC)-associated and sporadic renal angiomyolipomas and other solid renal tumors. We also focus on radiologic interventions and molecular targeting of the TSC genetic pathway.

Conclusion: Imaging plays a central role in the diagnosis and management of renal angiomyolipomas. It provides essential information to make the best therapeutic decisions about the interventional and pharmacologic options to help prevent bleeding and preserve functional parenchyma.

Keywords: CT; MRI; hereditary; mTOR; mammalian target of rapamycin; neoplastic syndromes; renal angiomyolipoma; tuberous sclerosis complex.
