For stroke, although most “clinical diagnoses” are reliable, there is a real risk of misdiagnosis, especially cerebral thrombosis. In brain tumors, chronic subdural hematoma, chronic brain abscess, a small number of cases early onset of disease is very much like cerebral ischemic stroke. So for the “stroke” diagnosis is still worth our attention and research. Each year we encounter similar brain thrombosis of the above three types of intracranial
