[Neuropathy caused by metronidazole. Report of a case and review of the literature].

A case of sensory neuropathy secondary to prolonged administration of metronidazole (MT) and tinidazole (TNZ) is reported. The patient received in the 6 months prior to admission, enough cumulative MT and TNZ to explain the development of a secondary neuropathy as reported in the literature. The present case is particularly interesting due to the length of evolution (38 months) which is the most prolonged reported up to now. It is also the first MT and TNZ neuropathy case reported in Spanish.
