Peripheral neuropathy in systemic vasculitis: clinical and electrophysiologic study of 22 patients.
Twenty-two patients with evidence of systemic vasculitis and peripheral neuropathy were clinically and electrophysiologically investigated in a retrospective study. Ten had a polyarteritis nodosa, 6 a probable polyarteritis nodosa, and 6 a Churg-Strauss syndrome. Nine patients presented clinically with mononeuropathy or mononeuropathy multiplex considered typical of ischemic involvement of peripheral nerve; nine had more diffuse neuropathy, two of them a symmetric polyneuropathy. EMG examination revealed more diffuse neuropathy than clinically predicted. Findings were of acute or subacute axonal neuropathy.
