Abstract

Recently, a new classification of renal angiomyolipoma (AML) has been introduced to clinical practice. This classification categorizes AMLs into three subtypes (fat-rich, fat-poor, and fat-invisible AMLs) based on quantitative CT and MRI criteria. Radiologists who get used to previous AML classification may have questions about how to apply a new classification. The purpose of this review is to answer the questions that are frequently asked about the new AML classification.

Keywords: Angiomyolipoma; Carcinoma, renal cell; Kidney; Magnetic resonance imaging; Multidetector computed tomography.
