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

USG images demonstrate a large kidney angiomyolipoma
