RESUMO
Objective To understand the effect of anti-cysticercus therapy for patients with cerebral cysticercosis and the changes of cysticercus on CT image after treatment. Methods The patients with cerebral cysticercosis were classified by the presentation of their brain CT image before treatment, then the effect of anti-cysticercus therapy on them after treatment was analyzed and the presentations of their brain CT images between before and after treatment were compared. Results There were different changes on CT image of cysticercus in brain tissues after anti-cysticercus therapy for different types of patients with cerebral cysticercosis. Type Ⅰ: the focus was absorbed completely after treatment in the majority of patients and calcificated in the minority. Almost all the patients were cured clinically after anticysticercus therapy. Type Ⅱ: the focus was absorbed completely in the minority, and one to two or more calcification dots were observed in the majority of patients. Anti-cysticercus therapy was effective. Type Ⅲ and Ⅳ: the absorption of focus was not very good and the effect of anti-cysticercus therapy was lower relatively. Conclusion The changes of CT image such as absorption, calcification, has important significance in forecasting prognosis and instructing clinical usage.
