Vasculitic Neuropathy

Vasculitic neuropathy results from inflammation of the blood vessels supplying peripheral nerves. Clinical features include painful asymmetric neuropathy, sensory loss, and weakness. Etiologies include systemic autoimmune diseases, infections, or primary vasculitis. Pathophysiology involves ischemic injury from vascular inflammation leading to axonal degeneration. Diagnosis relies on nerve biopsy, serologic markers, and clinical evaluation. Management includes immunosuppressive therapy; prognosis varies depending on disease severity and response to treatment.
