Substantial Improvement in a Nerve Conduction Study of Lymphoma-associated Demyelinating Neuropathy Treated by Intravenous Immunoglobulin and Chemotherapy

A 64-year-old woman with lymphoma-associated demyelinating neuropathy was treated by 6 cycles of R-CHOP with intravenous immunoglobulin in the first 2 cycles. We noted substantial improvement in the findings of a nerve conduction study (NCS) after the first cycle, followed by more protracted improvement during the second to sixth cycles. The improvement of the neurological symptoms paralleled the findings of the NCS. Our case provides important information for understanding the etiology and optimization of treatments for lymphoma-associated demyelinating neuropathy.
