[|Human|] i had a routine portable chest xray for my job because I had a positive PPD due to BCG vaccine. I was called to pick up the result. It says I have a prominent cardiomediastenial silhouet. Finding is prominent heart size. What does it mean? Should I go see a cardiologist or oncologist?
[|AI|]  Hello, The increased heart size is the cause of increased cardiomediastinal silhouette as per the X-ray. However, I would wish to reassure you this point that X-ray is not the best test to give a diagnosis of enlarged heart. It depends on a lot of things like any angulation, how deep did you inspire are some of them. So an 2 D Echo cardiograph would be the next test to confirm the diagnosis.  PPD positive men as we have to rule out tuberculosis.  In this region it may cause some fluid collection around the heart and lymph node enlargement in mediastinum causing its enlargement.  So a cardiologist for echocardiography would be the next reasonable hoverboards
