Initial appearance of an ill-defined shadow on a chest roentgenogram in a patient with aortitis syndrome

A 20-years-old woman with fever and an abnormal shadow on a chest roentgenogram was admitted to our hospital. High grade fever continued even after gradual disappearance of the ill-defined shadow on the right upper lobe (S3) with minor fissure deviation upward, while neck pain and bruit gradually developed. She was diagnosed as aortitis syndrome from a digital subtraction angiography. The initial appearance of an ill-defined shadow on a chest roentgenogram, considered as pulmonary infarction, is rare in the aortitis syndrome and this kind of onset is interesting in relation to the pathogenesis and diagnosis of this syndrome.
