Takayasu's arteritis (pulseless disease)

Case contributed by Dr Hani Salam

Case Discussion

CTA of a patient with Takayasu arteritis

Granulomatous inflammatory vasculitis affects walls of medium and large vessels. Marked intimal proliferation and fibrosis lead to occlusion and narrowing of aorta and involved arteries; aneurysms may also be found.

Age: 90% < 30 years (in contradistinction to all other arteritis).

More common in females. M:F 1:8

Types

  • type 1: aortic arch
  • type 2: abdominal aorta
  • type 3: entire aorta
  • type 4: pulmonary arteries

Radiographic features

  • stenoses of arch vessels (most common)
  • stenosis and occlusion of aorta (may mimic coarctation)
  • thickening of aortic wall
  • pulmonary artery involvement, 50%
  • abdominal aorta coarctation and renal artery stenoses
