PAINFUL BILATERAL LUMBAR RADICULOPLEXOPAT HY ASSOCIATED WITH EPSTEIN-BARR-VIRUS INFECTION

We report a case of polyneuropathy caused by primary Epstein Barr viru s (EBV) infection ill a 57-year-old patient. The primary EBV infection was confirmed by serology tests and EBNA (Epstein-Barr nuclear antige n) seroconversion. The main clinical sign was a highly painful subacut e, bilateral lumbar radiculoplexopathy with amyotrophy which responded to corticosteroids and complement treatment within a few months. The association of left facial paralysis neurophysiological signs of polyr adiculopathy and elevated protein levels in the cerebrospinal fluid de monstrate the varibility of peripheral neurological involvement in the same subject with EBV infection. This case also demonstrates the poor ly limites of dysimmune polyneuropathies, including lumbar radiculople xopathy which cart be considered as art exceptional variant.
