A Peculiar rotatory sensation around the right foot was complained of by a patient with left occipito-parietal subdural hematoma. A 65-year-old male had been suffering from the hypertension and arteriosclerosis for several years. He had a sudden attack of "difficulty in standing", ataxia and "black-out sensation" with headache. A left occipito-parietal subdural hematoma was removed. The patient noted peculiar rotatory sensations around the right foot, which were continuous and remained unchanged in character. We speculated that a lesion of the occipito-parietal lobe, especially around the 2 V area, caused this peculiar rotatory sensation. Though a defect of the visual field was noted, the eye tracking test and opto-kinetic pattern test were "within normal limits", probably due to sparing of the macula. We assumed that the abnormal rotatory sensation was closely related to the lesion of the 2 V area of the parietal region.
