Sunburst sign (renal angiomyolipoma)

Last revised by Dr Daniel J Bell on 29 May 2019

The sunburst sign refers to the appearance of arterial blush seen at selective arterial DSA of a renal angiomyolipoma.

Angiomyolipoma is a hypervascular renal mass that shows dense early arterial vascular network of tortuous irregular vessels with micro- or macroaneurysms.
