为探讨脑静脉系统血栓形成(CVST)误诊原因及早期诊断依据,通过对早期误诊的13例CVST的临床表现、脑脊液检查及影像学资料的分析,我们认为误诊原因有以下几点:本病临床表现繁杂,没有特异性。医生查体不仔细,忽略眼底的检查。医生思路狭窄,对此病缺乏足够的认识。影像学检查有其局限性。脑CT特征性表现少见,脑MRI+MRA是诊断CVST的主要手段,但在病初数天内MRI无诊断价值。
To investigate the causes of misdiagnosis of cerebral venous thrombosis (CVST) and the basis of early diagnosis, the clinical manifestations, cerebrospinal fluid (CSF) examination and imaging data of 13 cases with early misdiagnosis were analyzed. The reasons of misdiagnosis were as follows: Complex performance, no specificity. Medical examination body is not careful, ignoring the fundus examination. Doctors narrow thinking, the lack of adequate understanding of the disease. Imaging examination has its limitations. Brain CT features rare, brain MRI + MRA is the main means of diagnosis of CVST, but the first few days in the disease MRI no diagnostic value.
