    • Abstract:
      A 79-year-old woman was admitted to our hospital with a diagnosis of acute noncardioembolic stroke on division of the left middle cerebral artery with non-fluent aphasia. Although she was treated with dual antiplatelet therapy of aspirin and clopidogrel at first, she suffered a second stroke with enlargement of the same stroke lesion and worsening aphasia symptoms. There were only 46 days between the initial onset and recurrent stroke event.She had been diagnosed with polycythemia vera (PV) based on an increase in the blood cell count and a JAK2 mutation. The administration of hydroxyurea was effective for normalizing the blood cell count and preventing stroke recurrence. Cerebral infarction with or without any risk factors accompanied by an elevated blood cell count with a hematocrit value >45% can be PV, so it is necessary to start cytoreductive therapy as soon as possible in such cases.
