摘　　要：目的探讨脑静脉系统血栓形成(cerebral venous thrombosis,CVT)的误诊常见原因。方法复习65例CVT患者的病历资料,对误诊为其他疾病的病例进行分析。结果26例(约占40%)CVT患者曾被误诊为其他疾病,如病毒性脑炎(15例)、原发性头痛(3例)、上呼吸道感染(3例)、动脉血栓性脑梗死(1例)、原发性脑出血(1例)、重度子痫前期(1例)、视神经炎(1例)和神经症(1例),其中大部分病例的首发症状为头痛,临床表现缺乏特异性,容易误诊为其他常见病。结论CVT常因缺乏特异性的临床表现、头颅CT和MRI检查结果正常或征象不典型,没有及时行MRV或DSA检查,而被误诊。Objective To analyze the causes for the misdiagnosis of cerebral venous thrombosis （CVT）. Methods Data of sixty-five cases with CVT were reviewed. The causes for misdiagnosis were analyzed. Results Twenty-six eases（40%） were misdiagnosed as viral encephalitis （fifteen cases）, primary headache （three cases ）, infection of upper respiratory tract （three cases ） ,cerebral infarction （one case）, primary cerebral hemorrhage （one case）, severe pre-eclampsia （one case）, optic neuritis （one case） and neurosis （one case） .The onset symptom of most cases was headache without specificity. Conclusions Several causes are responsible for the misdiagnosis of cerebral venous thrombosis such as lack of specificity of the symptoms, normal manifestation of cranial CT or MRI scan, atypical signs of imaging and delay of MRV or DSA examination.
