Hello and welcome to HCM
1. Accentuated hilar and basal bronchovascular markings is quite a common finding in chest x-rays that could mean anything from normal to very serious disease (if associated with other findings). It is either to confirm the diagnosis or to start the investigation. It can be due to smoking
or chronic pulmonary disease.
2. Blunted CP angles are strong indication for Pleural effusion
(Collection of fluid in the lungs) but it can be due to other lung disease and lung hyper-expansion.
In short you are suffering from a lung disease may be acute or chronic depending upon the symptoms. In my advice consult your doctor soon and get your treatment started.
