Core Tip
Core Tip: Angiomyolipomas can be differentiated into triphasic benign angiomyolipomas (AMLs) and potentially aggressive epithelial AMLs. Triphasic AMLs can be further subdivided into classical fat-rich AMLs and fat-poor AMLs. Fat-poor AMLs can be hyperattenuating, isoattenuating or hyperattenuating with an epithelial cystic component. Recognition of the different imaging characteristics of AML types on computed tomography and magnetic resonance imaging is fundamental for differentiating this disease from other renal neoplasms.
