Recurrent cranial polyneuropathy.

General considerations on recurrent cranial polyneuropathy are made. In addition, a study carried out in 42 patients with recurrent cranial polyneuropathy (RCP) permitted the assessment of some parameters closely related to age, sex and evolution in order to elaborate an etiopathologic hypothesis. Female cases prevailed (31 females, 11 males); the interval between two episodes varied from 1 month to 39 years. 117 episodes were found (from 2 to 8 episodes in one patient). Immune, vascular and entrapment aspects are discussed.
