Hi everyone - I am looking for information on whether thymoma has been found in double seronegative patients?? It seems common in those with positive ACHR and but seems rare in the MUSK patients....does anyone know about the double seronegative patients??

I am thinking of asking my Neuro for a CT as I only had a chest x-Ray and I have persistent Costochondritis which is an inflammation of the chest wall - it started at the same time as my MG started up again and also seems to get worse with flare ups, I know this could be coincidence but I feel that it may warrant a CT scan? But if it is unlikely to find thymoma in double seronegative patients then maybe it's not worth pushing for the CT??

Thanks everyone - I don't know what I would do without all of your knowledge!!
