Overview
Ultrasound
On abdominal ultrasound, angiomyolipoma is characterized by
- Hyperechoic lesions on ultrasound, located in the cortex and with posterior acoustic shadowing
- 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
