Chronic subdural hematoma mimicking transient ischemic attacks.
A case is reported in which a chronic subdural hematoma caused recurrent episodes of neurologic dysfunction that simulated transient ischemic attacks. Possible pathophysiological mechanisms are: a subdural hematoma could cause local ischemia or focal epileptic discharges; a cerebral mass could cause cortical depression by mechanical stimulation; regional cerebral edema could cause vascular displacement and ischemia; or small repeated hemorrhages could cause transient neurologic deficits. Computer assisted tomography of the head is recommended in the differentiation of the two conditions.
