脑囊虫病诊断方法的探讨

为进一步探讨脑囊虫病的诊断方法，对43例具有中枢神经系统症状和体征的病人进行了脑部CT、血清和CSF囊虫抗体检查（ELISA法），32例CT无典型脑囊虫病改变的患者做了脑MRI检查。结果11例（25．6％）CT表现为多发圆形低密度灶，部分间有点状钙化，为脑囊虫病的典型改变，余32例改变不典型或无异常改变。血清囊虫抗体阳性37例（86．0％），CSF囊虫抗体阳性32例（74．0％）。27例（84．4％）脑MRI可见典型脑囊虫病改变，5例为非特异性改变。认为脑囊虫病的诊断应结合临床表现、免疫学检查结果和影像学改变综合分析，MRI对脑囊虫病的诊断价值优于CT。

A study on diagnostic methods of cerebral cysticercosis

In order to investigate the diagndric methods of cerebral cysticercosis, 43 patients with CNS symptoms and physical signs were observed. All of the cases were examined by cerebral CT, serum and CSF Cab test (ELISA),32 cases of the above with no typical cerebral cysticercosis alterations on CT were examined by cerebral MRI. Results: Typical alterations of cerebral cysticercosis were checked by CF in 11 cases (25.6% ) .Serum Cab test (+ ) in 37 cases (86.0%),CSF Cab (+ ) in 32 cases (74.0%). Typical alterations of cerebral cysticercosis were cheched by MRI in 27 cases of the 32 cases (84.4% ).The results show tha the diagnosis of cerebral cyeticercosis should combine clinical manifestations, immunology tests and radiology examinations. MRI is more advantages than CT in the diagnesis of cerebral cysticercosis.
