[Polyarteritis nodosa as a cause of sensory motor polyneuropathy.Apropos of a case].

We present a case of nodose polyarteritis (NPA) in a 65-years-old man with clinical manifestations at the level of the peripherical nervous system (PNS) as a subacute sensorimotor polyneuropathy. We believe that this is an interesting case due to the outlined symptomatology and the first clinical signs, not as common as the multiple mononeuropathy. The diagnosis was established through biopsy of muscle-nerve, without observing aneurysms at the Divas and with negative results for the Hepatitis B markers. Response to corticoid and immunosuppressive therapy was positive.
