[A case of the Ramsay-Hunt syndrome (herpes zoster of the geniculate ganglion) with concomitant C2 and C3 nerve involvement].

A case of Ramsay-Hunt syndrome (herpes zoster of the genicular ganglion with paresis of the facial nerve) presenting concomitant involvement of the sensitive nerve roots C2 and C3 is reported. The main aetiopathogenetic hypotheses as reported in the literature are presented and an attempt made to formulate a standard aetiopathogenetic theory comprising lesions to the motor nerve fibres and those of the sensitive nerve fibres.
