Abstract: 　AIM: To observe the changes in cerebral computed tomogram (CT) in cerebral parenchymal cysticercosis after albendazole treatment. METHODS: Cerebral CT scanning was conducted in 57 patients with cerebral cysticercosis in our hospital before, during and after albendazole treatment. RESULTS: Cerebral CT might be normal before onchospheres became cysticercariae in the brain. Small cystic lesions could turn into other CT signs of cerebral cysticercosis after albendazole treatment. CONCLUSION: Normal cerebral CT cannot rule out the disease. Small cystic lesions are the earliest pathological and active signs of the disease. Nodular focus occurs after the death of Cysticercus and calcification is the final outcome of the disease. \;

Key words: Cerebral parenchymal cysticercosis, computed tomogram
