Overview

On abdominal ultrasound, angiomyolipoma is characterized by hyperechoic lesions and posterior acoustic shadowing in the cortex.

Ultrasound

On abdominal ultrasound, angiomyolipoma is characterized by:

• Hyperechoic lesions and posterior acoustic shadowing in the cortex
• In the setting of tuberous sclerosis:
  • Lesions may be so numerous that the entire kidney is affected
  • Appear echogenic with loss of normal corticomedullary differentiation
• Contrast-enhanced ultrasound of demonstrates:
  • Angiomyolipoma lesions tend to enhance peripherally
  • Decreased central enhancement of angiomyolipoma, compared with normal cortex
