We report the relationship between cerebral blood flow (CBF) and neuropsychologic tests in a patient with a chronic subdural hematoma suffering from severe dementia and left hemiparesis. Regional CBF was quantified using 99mTc-HMPAO SPECT and 133Xe-CBF. CBF-SPECT could detect the hematoma which was isodense by CT scan and the neuropsychological test improved remarkably with the increase in CBF after surgery. We conclude that if there is a strong clinical suspicion of subdural hematoma and CT scan is not diagnostic then CBF-SPECT may be valuable in localizing the hematoma and monitoring the effect of operation.
