Abstract:
Objective To study the changes of cerebral function and pathological morphology before and after the antiparasit-ic treatment with albendazole and praziquantel in patients with cerebral cysticercosis. Methods The data of EEG and neuroimag-ing of 412 patients with cerebral cysticercosis were retrospectively analyzed. Results Before the treatment,the mild abnormali-ty,moderate abnormality,and severe abnormality were observed in 40.53%,45.63% and 13.84% of the patients respectively, which mainly showed the diffuse or focal irregular slow waves,or epileptiform discharges found in the abnormal brain waves. CT/MRI manifestation could be divided into six types,including single sacculus type(23.59%),multiple sacculus type(44.42%), encephalitis type(13.59%),coexistence of macrocyst and sacculus type(4.85%),calcification type(2.18%),and mixed type (11.41%). After 3 courses of the treatment,the normal and improved EEGs were observed in 79.85%and 20.15%,respectively. CT/MRI showed the foci being all absorbed(77.18%),being most absorbed(20.63%),and being no changes(20.18%)which were calcified focus. When cerebral cysticercosis were in acute stage(the single and multiple sacculus type,encephalitis type, and macrocyst and sacculus coexistence type),the therapeutic effect was good;while in the mixed type,the therapeutic effect was relatively poor. If cysticercosis were in the calcification stage,the patients only needed the heteropathy. Conclusions In the pa-tients with cerebral cysticercosis,EEGs show the mild to severe abnormalities,and CT/MRI mainly shows the multiple sacculus type. After the treatment,the abnormal EEGs are gradually recovered and the low density foci can be all absorbed,but some calci-fied focus still exist in some patients.
