[Copper deficiency as a treatable cause of myelopathy].

Copper deficiency myelopathy is an important and treatable differential diagnosis of vitamin B12 deficiency, of degenerative diseases presenting with the cardinal sign ataxia, and less often of motor neuron diseases. We report a 30-year-old female who presented with progressive gait disorder and sensory disturbances in her feet. Neurological examination showed tetraparesis with spastic ataxia. Laboratory investigations showed malabsorption, anemia, and leukopenia. Further extensive diagnostic investigations revealed copper deficiency due to malabsorption as the probable cause of the neurological deterioration. After oral copper substitution was started, the progression of her neurological symptoms could be stopped.
