This case report presents two patients who were diagnosed with non-systemic vasculitic neuropathy (NSVN). The phenotypes were atypical: 1) slowly progressive neuropathy and 2) plexopathy in contrast to the classic NSVN phenotype: painful, asymmetric with subacute progression. Both patients had remarkable responses to the immunosuppressants prednisolone and rituximab, and the cases highlight the importance to consider NSVN as a differential diagnosis of patients with neuropathy of unknown aetiology, as treatment can be initiated to avoid irreversible nerve damage.
