I had a chest xray done today and results are as follows: heart shadow not enlarged. Calcification noted in the aortic knuckle. No hilar abnormality. Lungfields clear of consolidation. No pleural pathology shown. My concern is the calcification noted in aortic knuckle.
It is a physiological finding, and you need not worry about the same.  It occurs due to aging and seem commonly in general population above 50 years of age and more frequently as age advance.  No treatment needed for the same.  Regards Chat Doctor.
