Abstract: Objective To investigate the changes of brain CT imaging in patients with cerebral cysticercosis during the period of anti?cysticercus chemotherapy. Methods A total of 380 inpatients that were conformed to the practical diagnostic criteria of cerebral cysticercosis were enrolled in this study in the Third Affiliated Hospital of Shandong Academy of Medical Sciences from May 2010 to May 2015. All the patients were given anti?cysticercus chemotherapy （albendazole and praziquantel）. All the patients received brain CT scan， and of which 210 received enhanced scan. The data of CT imaging were systematically reviewed. Results Before the treatment， the CT images of the patients showed single or multiple small cystic（s） with low density and small nodule?like cephalomere with high density. The re?examinations of CT showed that there were 81.58% （310/380） of the patients whose low density foci were completely absorbed， there were 16.32% （62/380） of the patients whose foci were mostly absorbed， and there were 2.11% （8/380） of the patients whose foci were calcified. Along with the prolongation of treatment time， the side effects were gradually reduced， and in the third course of treatment， the foci were absorbed or calcified in most of the patients. Conclusion CT examination can diagnose the lesion site， range and classification of cerebral cysticercosis， and can evaluate the effect of the therapy according to the changes of CT imaging during the period of anti?cysticercus chemotherapy.
