I wondered if MG caused swollen tongue and I do find a case report saying this can happen. Survey of patients also indicates this is possible, but it's unclear whether this is due to medications or the disease itself.
WebMD also says swollen tongue can be caused by dehydration. If you are having trouble swallowing, that could contribute to dehydration. However, should be easily resolved with IV hydration, if that were the case.
