Abstract

Introduction: Paraneoplastic lower motor neuronopathies have been reported rarely with Hodgkin lymphoma. Methods: We report a case of rapidly progressive motor neuronopathy preceding the diagnosis of Hodgkin lymphoma. Results: A 31-year-old woman developed subacute rapidly progressive quadriparesis. Electrodiagnostic studies revealed a severe diffuse disorder of motor neurons and their axons. Symmetric enhancement of the cauda equina motor nerve roots was notable on magnetic resonance imaging scan. Further imaging demonstrated an enlarged supraclavicular lymph node, and biopsy revealed Hodgkin lymphoma. A final diagnosis of paraneoplastic motor neuronopathy was made after investigations for alternative causes of motor neuronopathy were unrevealing. Neurological improvement was seen with combined treatment of the underlying malignancy and intravenous immunoglobulin. Conclusions: Paraneoplastic causes should be considered in the differential diagnosis of subacute motor neuronopathy, as the neurological presentation may precede cancer detection. Combinations of lymphoma treatment and immunotherapy may result in a favorable outcome.
