The following tests are mainly done for parasitic brain infections, including routine blood, stool, cerebrospinal fluid, immunological examination, head CT, and head MRI. For example, the total white blood cell count is normal in intracerebral cysticercosis infection, which may be elevated in individual patients, and a small number of patients will show an increase in eosinophils.1 Tapeworm eggs can be found through stool examination, suggesting that the patient has a diagnostic basis for brain cysticercosis. The pressure of cerebrospinal fluid examination will be normal or elevated, the cerebrospinal fluid is mainly elevated lymphocytes and eosinophils may be elevated. 2. Immunological examination, if the cerebrospinal fluid is positive for cysticercus antibodies suggests that the patient is in the active stage of cysticercosis. CT examination of the head can play an important role in the diagnosis of cysticercosis and cerebral parasitosis, which can detect the lesions, determine the location, size and number, and show the morphology of cerebral edema, hydrocephalus and ventricles. 3. It is better than CT examination.
