Several months ago an X-ray showed that I had a 4 mm nonspecific nodular and a small right pleural effusion. I insisted that my doctor did more testing on me. She had me take another x-ray. This time they told me that the nodular and the right pleural effusion were not on the x-ray. I have a hard time believing my doctor. She said sometimes it happens. I asked her how do I know it won't be back again on the next x-ray? Of course due to insurance limitations I cannot have another x-ray to see if the 4mm monspecific nodular and small right pleural effusion is back. Will you please tell me what is going on?

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the disappearance of a 4 mm nonspecific nodular shadow and small right pleural effusion which was previously reported on x-ray chest several months back.
From your description, it comes out that you have a history of heart disease for which you have had treatment in the past. It seems that you have phantom tumor which is accumulation of pleural effusion in the interlobular spaces of the lungs. They appear in patients with heart failure simulating a lung tumor but disappearing with medical treatment. The encystment of the fluid is apparently due to congenital defects in the pleura, which tends to store up the transudate produced by heart failure. That might be the reason the nodular shadow and pleural effusion has cleared now possibly with the treatment of heart failure.
Hope this helps. Take care.
