The authors reported a case with acute right, middle cerebral artery infarct in which the early infarct area was detected by CTP recovery later after the treatment. The patient had hypoxia and tachypnea from pulmonary edema during acute ischemic stroke, which may have accentuated the ischemic change in cerebral hemodynamic. With treatment, the causes of hypoxia were corrected and the patient got better and some parts of the brain, previously identified as infarct, turned out to be normal.
