Abstract
We report a 62-year-old woman with a past history of painful central visual loss who developed progressive quadriparesis and bulbar palsy. Neurological examination revealed widespread upper and lower motor neuron signs in the bulbar region and extremities. Electromyography demonstrated widespread active chronic motor axon loss. Magnetic resonance neuroimaging enhancing callosal and periventricular white matter lesions and cervical and thoracic cord hyperintensities. Cerebrospinal studies revealed fluid analysis was consistent with multiple sclerosis. The patient died of respiratory failure two years after presentation, and autopsy revealed multifocal demyelination involving the corpus callosum, cerebellum and spinal cord as well as pathologic findings typical of amyoand trophic lateral sclerosis. A review of the literature confirms the exceedingly unusual combination of amyotrophic lateral sclerosis with multiple sclerosis. (ALS 2000; 1: 349–353)
