[A case of micrographia with the right hand due to left putaminal infarction]. 1989

T Yoshida, and A Yamadori, and E Mori

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.

D002544	Cerebral Infarction	The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).

D000381	Agraphia	Loss or impairment of the ability to write (letters, syllables, words, or phrases) due to an injury to a specific cerebral area or occasionally due to emotional factors. This condition rarely occurs in isolation, and often accompanies APHASIA.
