please tell me what was the cause of pleural effusion
. It could be due to infection like pneumonia
or may be due to fluid overload situation.
'Prominent bronchovascular markings in bilateral lung fields means either Infection in respiratory passages or fluid overload. Infection may be acute or chronic. If radiologist
reports increased bronchovascular markings but clinical situation is not supporting any thing it can be ignored and film should be taken as normal.
Improvement of condition can be said if there is clinical improvement also.
So your treatment should be based on clinical judgement of your treating physician
