Pulmonary artery obstruction due to giant cell arteritis.
Giant cell arteritis is often referred to in the context of polymyalgia rheumatica with temporal artery involvement. There are, however, more malignant forms of presentation of this necrotizing arteritis involving either the great vessels of the aorta or, occasionally, the pulmonary arteries. Our case relates to giant cell arteritis presenting as pulmonary artery obstruction in a patient without polymyalgia rheumatica or extensive aortic or proximal great vessel involvement.
