A case of nonsystemic vasculitic neuropathy presenting with multiple cranial neuropathies

Serologic markers including anti-neutrophil cytoplasmic antibodies (ANCA), anti-nuclear, paraneoplastic, and anti-Ro/La antibodies, the immunologic markers for syphilis, hepatitis B and C, human immunodeficiency virus (HIV), and serum and urine protein electrophoresis were unremarkable. About 2 months after discontinuation, respiratory difficulty developed and limb weakness got aggravated. Because of aspiration pneumonia, intravenous immunoglobulin was administered for 5 days instead of steroid pulse therapy.
