A rare cause of hemoptysis in a young female

Takayasu's arteritis (TA) is also termed pulseless disease owing to the frequent occlusion of large arteries originating from the aorta and its major branches. It is an uncommon chronic inflammatory progressive idiopathic large vessel vasculitis with a predilection for young women of childbearing age group. Fatigue, malaise, and fever are the frequently encountered early symptoms of TA. Hemoptysis is not commonly seen as an initial presentation of TA. The subclavian artery is most commonly involved, and the disease is usually discovered accidentally owing to pulse asymmetry. In addition, pulmonary artery involvement is not common in TA. Here, we present a case of a young female presented to us with hemoptysis with pulmonary artery involvement with a de novo diagnosis of TA.
