Overview

CT scan manifestations in Takayasu arteritis include mural thickening (typical manifestation), calcification of the thickened wall, and double ring enhancement pattern.

Key CT Findings in Takayasu's arteritis

  • In patients with TA, the typical manifestation on CT images is the concentric mural thickening of the involved arteries.[1]
  • CT scan manifestations in Takayasu arteritis include:
    • Mural thickening (most important finding in the early phases of the disease)
    • Calcification of the thickened wall (usually transmural in 27% of patients)
    • Double ring enhancement pattern
