초록
Predominant involvement of a particular group of fingers due to a central nervous system lesion has been described aspseudoperipheral palsy. Two patients visited our hospital with isolated weakness of a particular group of fingers due tosmall cortical infarctions. A 51-year-old woman suddenly developed weakness in her left index and middle fingers. Thebrain MRI showed a small infarct in the right frontal cortex. A 67-year-old man was sudden difficulty using his chopsticksand had weakness in his right thumb and index finger. The brain MRI showed a small infarct in the left precentral cortex.
