  • Clinical details:
    • A 40-year-old female. Known Takayasu arteritis with 3 vessel gut disease. Bilateral renal artery stenosis and left subclavian artery stenosis. New mass lesion around the abdominal arterial tree. On mycophenolate mofetil and prednisolone

  • Legend:
    • Moderate diffuse uptake in the thickened wall of the aortic arch and left subclavian artery in keeping with active large vessel vasculitis.

  • Teaching points:
    • Diffuse smooth uptake in the wall of the large vessels is suggestive of large vessel vasculitis.

    • The aorta is very often involved.

    • CT, MRI, and FDG PET are complementary.

    • FDG PET is useful to assess areas of activity in previously treated patients.
