Macaroni's sign

The macaroni sign is a sign seen in Takayasu arteritis on ultrasound. It represents the smooth, homogeneous and moderately echogenic circumferential thickening of the arterial wall that occurs in Takayasu arteritis.

The sign is highly specific for Takayasu arteritis, more commonly noted in the common carotid artery (CCA).
