title: Peripheral neuropathy and solitary myeloma: analysis of serum and CSF IgG in two cases.
abstract: Clinical and laboratory findings of two patients affected by solitary myeloma, IgG3 lambda type, with peripheral neuropathy are reported. In both cases the same IgG isoelectrofocusing pattern was found in cerebrospinal fluid and serum samples. Data are consistent with damage of the blood-brain barrier.
