[Progressive muscular weakness due to subacute postinfectious polyradiculitis and myelitis].
In a 67-year-old patient, generalised stable muscular weakness preexisting for several years became rapidly progressive within a few weeks prior to hospitalisation. He died one month after admission from acute cardiocirculatory failure. There was no history of muscular pain, clinical examination showed weak or absent tendon reflexes, hyposensibility of the dorsa of his feet, fasciculations and myocloni of the muscles of the lower limbs as well as a generalised muscular atrophy. Polyneuropathy due to diabetes mellitus and monoclonal IGG-kappa-type gammopathy were preexisting. CSF examination showed inflammatory cerebral fluid changes and further investigations revealed inflammatory polyradiculopathy affecting mainly motor nerve fibres. There was evidence of a reactivated varicella-zoster infection in serum and in the cerebrospinal fluid samples. The search for a tumour, vasculitis or a drug-related cause for this syndrome remained negative. Neuropathological examination at autopsy showed subacute polyradiculitis accompanied by myelitis. The most probable cause of this disorder is immune-mediated polyradiculitis after varicella-zoster infection.
