A 43-year gentleman with recurrent hemoptysis, recurrent genital and oral ulcers since 5 years.
- 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).

DIAGNOSIS:
Right pulmonary artery aneurysm with partial eccentric thrombus.
DISCUSSION:
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:
- Pulmonary thromboembolism.
- Pulmonary artery aneurysm.
- Sinus of Valsalva aneurysm.
- SVC syndrome.
- Intracardiac thrombosis.
- Mediastinal fibrosis.
- Intestinal ulceration (and inflammatory changes).
- Budd-Chiari syndrome.
- 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.
