title: [A case of micrographia with the right hand due to left putaminal infarction].
abstract: Micrographia due to focal cerebral disorder is very rare. We described a patient with micrographia due to a left putaminal infarction. Following an infarction involving the left putamen and corona radiata, a 58-year-old right-handed man developed micrographia with the right hand, right facial palsy, right hand clumsiness and slight aphasia. Micrographia finally disappeared by the seventh month. No parkinsonian features were noted. Our case suggests that micrographia is a disorder of the motor control system of handwriting which exists in the contralateral putamen, and has no relation with extrapyramidal signs like rigidity, tremor or akinesia.
