Vasculitis involving peripheral nerves usually presents as an acute asymmetrical axonal neuropathy. We report a 67‐year‐old man with a symmetrical subacute neuropathy in which nerve conduction studies showed prominent conduction block, a finding indicative of demyelination. Sural nerve biopsy showed a vasculitic neuropathy with invasion of blood vessel walls by inflammatory cells and a mixture of nerve fiber loss and demyelination. The demyelination in this case was presumably a consequence of subinfarctive nerve ischemia. © 1998 John Wiley & Sons, Inc. Muscle Nerve 21:1084–1088, 1998.
