title: Spinal myoclonus associated with vitamin B12 deficiency.
abstract: We report a 85-year-old female patient with involuntary and regular movements restricted to abdominal muscles, resembling belly dance, with additional clinical features; ataxia, impaired cognition, neuropathy and glossitis. We initially excluded the possible cortical and spinal structural abnormalities with magnetic resonance imagings and performed routine blood analysis which revealed that serum vitamin B12 (vB12) level was under normal ranges. The relation of low serum vB12 level and myoclonus is speculative and very few studies have demonstrated such patients. In this case report, serum vB12 deficiency is discussed in the context of its probable role in the generation of spinal myoclonus.
