- Abstract
Pathological data suggest that inflammatory activity evolves from the adventitia to the intima and finally encloses the whole layer.[1] Computed tomography (CT) and magnetic resonance imaging (MRI) can depict signs suggestive of vascular inflammation in the arteries such as arterial wall thickening, increased wall signal intensity, and perivascular edema. Although CT or MRI is a well-established modality for primary diagnosis of Takayasu arteritis, it has a limited clinical role in the long-term follow-up of those patients when reactivation of the disease is suspected. Carotid ultrasonography indicated diffuse, homogeneous, circumferential thickening of the intima-media complexes, so-called "macaroni sign", in both common carotid arteries (CCA) (Figure 1A).
