Windsock sign (aortic dissection)

Dr Zishan Sheikh et al.

The windsock sign refers to appearances seen in type A thoracic aortic dissections on contrast CT. It results from intimo-intimal intussusception between the true and false dissected lumens of the thoracic aorta. The altering density of contrast between the dissection lumens which taper distally resembles a windsock.
