[Recurrent Miller-Fisher syndrome associated with brachial neuritis].

The clinical and electrophysiological evolution of a 24-year-old patient with Miller-Fisher's syndrome and findings of mild peripheral neuropathy in the electromyographic study is reported. The patient had been treated six years previously for a similar disease and he recovered in 2 months. During the plasmapheresis therapy of the second episode he developed pain and weakness of the left shoulder girdle, and the EMG was consistent with bilateral brachial neuritis. The disease had improved clinically after 6 weeks, except for supracapsular brachial neuropathy; this territory remained denervated after 3 months of evolution. A diagnosis of Crohn's disease had been made between both episodes. The discussion focuses on the rarity of recurrent forms of Miller-Fisher's syndrome and the association of the reported case with brachial neuritis and Crohn's disease.
