Case in brief
A middle-aged male presented with acute symptoms of autoimmune diencephalitis, including headache, fever, seizures, and impaired consciousness, lasting over three months. Diagnosis was confirmed through laboratory tests and MRI. Treatment included glucocorticoids, intravenous immunoglobulin, mycophenolate mofetil, and efgartigimod. The addition of efgartigimod allowed for successful glucocorticoid tapering and led to gradual recovery.
Diagnostic / clinical pearl
Efgartigimod may serve as an effective adjunctive therapy in managing autoimmune diencephalitis, particularly in cases dependent on immunotherapy.
