Overview

On digital subtraction angiography, angiomyolipoma is characterized by hypervascular lesions, microvascular aneurysms, and absent AV shunting.

Other Imaging Findings

Digital Subtraction Angiography

On digital subtraction angiography, angiomyolipoma is characterized by:

• Hypervascular lesions
• Microaneurysms or macroaneurysms
• Sharply marginated
• Dense early arterial network
• Late whorled appearance
• Absent AV shunting
