"In grade 1 (radiologic changes without symptoms), it is recommended to clinically monitor the patient for 2-3 days and repeat imaging every 3 weeks 7.

In the most severe cases requiring admission to hospital or ICU, other immunosuppressors such as intravenous immunoglobulin (IVIG), infliximab, cyclophosphamide and mycophenolate mofetil can be used 4."
