[Involvement of the cranial nerves disclosing multiple myeloma].

Diseases of cranial nerves are very seldom associated with multiple myeloma. However, their occurrence as a harbinger of multiple myeloma seems to bear a particular significance and is worth mentioning. In the present paper, we discuss two cases in which disorders of cranial nerves heralded Kahler's disease. The patients presented with posterior laterocondylar space and cochleovestibular (otoliquorrhea) syndromes, respectively. We stress the diagnostic problems involved and analyze the pathogenesis of diseases of the nervous system associated with multiple myeloma. Diseases of cranial nerves are seldom associated with multiple myeloma. Nonetheless, the clinical setting and laboratory tests will direct the diagnosis. The same does not hold true when one is confronted with Collet-Sicard's syndrome or cochleovestibular syndrome accompanied by otoliquorrhea.
