Abstract

We report a case of sonographic follow-up showing brightening of the diffuse circumferential thickening (halo) of the carotid artery wall (the so-called “macaroni sign”) in a patient with decreasing inflammatory activity of Takayasu arteritis over a 6-month period. Sonographic follow-up in patients with Takayasu arteritis may be a useful complementary tool for evaluation of inflammatory activity. Besides a reduction of halo diameter, an increase in wall echogenicity appears to be a sign of decreasing inflammation. © 2011 Wiley Periodicals, Inc. J Clin Ultrasound 2013
