The incidence of arterial thrombosis in patients with protein C deficiency is relatively low compared with that of venous thrombosis. To our knowledge, there is no previously published report of a protein C deficiency patient with simultaneous thromboses in the pulmonary artery and innominate artery in the English literature. We present a case of a protein C deficiency in which the presence of concurrent clots in the pulmonary arteries and innominate artery demonstrated on a pulmonary computed tomographic angiography provided an important clue permitting diagnosis of the deficiency.
