title: Peripheral neuropathic syndromes in giant cell (temporal) arteritis.
abstract: Of 166 consecutive patients with histologically confirmed giant cell (temporal) arteritis (GCA) seen during a 3-year period, 23 (14%) had clinically diagnosed peripheral neuropathic syndromes temporally coincident with clinically active GCA. Electromyography and nerve conduction studies were performed in 16, confirming abnormalities in all. Of the 23 patients, 11 had a generalized peripheral neuropathy, nine had multiple mononeuropathies, and three had a mononeuropathy. The nerves affected as mononeuropathies were the median, ulnar, peroneal, tibial, and sural nerves, and the C-5 and L-5 nerve roots. Angiography, performed in two patients, demonstrated widespread arteritis involving the lower limbs and, after 3 months of oral corticosteroid treatment in one of these patients, an amputation specimen showed chronic arteritis.
