Before the infarction occurred, perfusion CT imaging disclosed early but reversible ischemic injury on the day of hemorrhage. Dehydration and hypotension are both possibly contributing factors of progressive injury from reversible ischemia due to infarction. Although the patient underwent successful bypass surgery, 1 month after the ictus the neurobehavior evaluation still showed marked executive dysfunction. The authors address that, in hemorrhagic-type moyamoya disease, early perfusion CT scanning is not only a powerful tool to identify the high-risk group of patients who could experience subacute infarction, but also alarms neurosurgeons to eliminate any predisposing factors when it shows reversible ischemic injuries.en[SDGs]SDG3acetylsalicylic acid; dipyridamole; adult; anamnesis; aptitude test; article; brain angiography; brain artery bypass; brain function; brain hemorrhage; brain infarction; case report; clinical feature; computer assisted tomography; conservative treatment; disease predisposition; female; human; laboratory test; moyamoya disease; priority journal; acute disease; brain hemorrhage; brain ischemia; dehydration; intracranial hypotension; moyamoya disease; prediction and forecasting; radiography; risk factor; Acute Disease; Adult; Brain Ischemia; Cerebral Hemorrhage; Dehydration; Female; Humans; Intracranial Hypotension; Moyamoya Disease; Predictive Value of Tests; Risk Factors; Tomography, X-Ray Computedjournal article10.3171/JNS.2008.109.12.1049190357182-s2.0-58149377373
