New Trends in Diagnosis and Imaging Follow Up of Renal Angiomyolipomas Part I: Classic AMLs

Angiomyolipomas (AMLs) are composed of three tissue types: vascular, adipose, and muscular, each of which uniquely affects their imaging features and potential impact on clinical outcomes. The authors provide a framework for understanding how the pathological features of AMLs translate into imaging features, which can be used for categorization and for differentiating AMLs from malignant renal cell carcinomas (RCCs), which may have similar appearances.

Upon completing this activity, the reader should be able to

1. Identify imaging features of AMLs.

2. Distinguish AMLs from echogenic RCCs on ultrasound.

3. Manage small (<1 cm) echogenic renal masses detected on ultrasound.
