  • Fig 1 & 2. Axial and Sagittal contrast CT Pulmonary angiogram images demonstrate a large saccular aneurysm arising from the superior segmental artery of right lower lobar pulmonary artery with diffuse wall thickening – probable eccentric thrombus. There is compression of distal lower lobe segmental pulmonary arteries by the aneurysm (arrow).

Behçet disease is a multisystemic and chronic relapsing inflammatory disorder characterized by the histopathologic finding of nonspecific vasculitis involving various sized vessels in multiple organs.

Key imaging manifestations are:

  1. Pulmonary thromboembolism.
  2. Pulmonary artery aneurysm.
  3. Sinus of Valsalva aneurysm.
  4. SVC syndrome.
  5. Intracardiac thrombosis.
  6. Mediastinal fibrosis.
  7. Intestinal ulceration (and inflammatory changes).
  8. Budd-Chiari syndrome.
  9. Cerebral venous thrombosis.
  • Identification of a vascular lesion is important because it seriously affects a patient’s prognosis. The leading cause of sudden death in patients with Behçet disease is rupture of a large aortic or arterial aneurysm
  • To improve the detection of these various radiologic findings, examinations should be well-selected and optimized in patients with Behçet disease.
