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
