Diagnostic Criteria for Neurocysticercosis

Absolute

·        Histologic demonstration of the parasite from biopsy of a brain or spinal cord lesion

·        Cystic lesions showing the scolex on CT or MRI

·        Direct visualization of subretinal parasites by fundoscopic examination

Major

·        Lesions highly suggestive of neurocysticercosis on neuroimaging studies

·        Positive serum immunoblot for the detection of anticysticercal antibodies

·        Resolution of intracranial cystic lesions after therapy with albendazole or praziquantel

·        Spontaneous resolution of small single enhancing lesions

Minor

·        Lesions compatible with neurocysticercosis on neuroimaging studies

·        Clinical manifestations suggestive of neurocysticercosis

·        Positive CSF ELISA for detection of anticysticercal antibodies or cysticercal antigens

·        Cysticercosis outside the central nervous system

Epidemiologic

·        Evidence of a household contact with T. solium infection

·        Individuals coming from or living in an area where cysticercosis is endemic

·        History of frequent travel to disease-endemic areas

CSF, cerebrospinal fluid; ELISA, enzyme-linked immunosorbent assay.
