Hemorrhage or Ischemia? Context: A 78-year-old woman was transferred directly to an ICU because of intracerebral hemorrhage. However, on careful review of the initial imaging, the likely diagnosis was ischemic stroke and reperfusion hemorrhage. Case report was explained. The patient suffered significant reperfusion hemorrhage. A CT angiogram revealed contrast extravasation "spot sign" in the bed of the expanding hemorrhage and an occlusive thromboembolism distal to the initial ischemic insult.
