A month and a half ago I had a CT done because there was a concern I had a blood clot in my lungs. There was no blood clot but an enlarged (3 cm x 2cm) pretracheal lymph node was found. Two weeks later I had a PET scan and it showed I had a large pericardial effusion, as well as several other “hot spots” in my cervical and mediastinal lymph nodes, however the doctor felt it was most likely to inflammation and infection. The immediate concern was the fluid around my heart and I was hospitalized. They drained the fluid and everything came back “normal” so they don’t know what caused it, however they didn’t seem overly concerned and said something it can just happen from an infection... but I was not sick so I don’t feel good about that. Some labs came back abnormal, but just slightly so again, they were not concerned. I am to have a repeat PET scan in October. I seem to be the only one worried about lymphoma. I guess I am looking for support, advise, or to see if anyone has experienced anything similar? Prior to this I was (am) a healthy 36 year old woman.
