Pulmonary artery aneurysm in a young female with Takayasu arteritis

In suspected cases of systemic vasculitis, imaging studies should include the pulmonary artery. This is a rare case of Takayasu arteritis with a large pulmonary aneurysm. Medical management is the first line and vascular intervention if fails prior.

Takayasu arteritis (TA) should be suspected in young women presented with hypertension, carotidynia, and claudications. Pulmonary artery involvement is frequent, occurring in 20%-50% of patients with TA. However, this case highlights the rare presentation of TA with a large pulmonary aneurysm and minimal aortic involvement. Medical management including immunosuppressive agents and biological therapies remains an important role, with vascular intervention remains as an option if medical therapy failed.
