Repeat X-ray and CT Scan of Thymus
Generally, how often do you feel that MG patients should get a chest X-ray and/or CT scan of the chest to be sure that there is not an enlarged thymus or thymoma present?
I am asking this question for those of us who have not had a thymectomy and who had a normal chest X-ray and CT scan after a diagnosis of MG.
Thank you for your input.
There is no absolute guideline or study that can absolutely answer your question. I can say that a chest x-ray does not need to be done. It is an inadequate study for this purpose. If you are in remission (doing well, on no medications) or well-controlled on minimal medications or have only ocular MG, I do not think any study is necessary. I obtain a repeat CT of the chest, if a patient has moderate to severe MG not responding to medications.
