Polycythemia Vera With Multiple Cerebral Infarctions Complicated By Cerebral Microhemorrhage: A Report of Two Cases

Polycythemia vera (PV) has multiple vascular risk factors and gradual onset and is an important risk factor for stroke. The first manifestation in some patients with PV is thrombotic cerebrovascular events. However, there are few reports on polycythemia vera with multiple cerebral infarctions and cerebral microhemorrhage. The clinical and imaging features of two PV patients with multiple cerebral infarctions complicated by cerebral microhemorrhage were analyzed retrospectively in order to improve the clinical understanding of the disease.
