Overview

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

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 shows:
- Lesions tend to enhance peripherally
- Decreased central enhancement, compared with normal cortex

USG images demonstrate a large kidney angiomyolipoma
