Diagnostic criteria and degree of certainty for the diagnosis of neurocysticercosis according to Del Brutto et al. [20].

Footnotes:CT: Computed Tomography, MRI: Magnetic Resonance Imaging, EITB: Enzyme-linked immunoelectrotransfer blot assay, CSF: Cerebrospinal Fluid, ELISA: Enzyme-linked immunosorbent assay, CNS: Central Nervous System.*CT or MRI showing cystic lesions without scolex, enhancing lesions, or typical parenchymal brain calcifications.†Enzyme-linked immunoelectrotransfer blot assay using purified extracts of Taenia solium antigens, as developed by the Centers for Disease Control and Prevention (Atlanta, GA).‡Solitary ring-enhancing lesions measuring less than 20 mm in diameter in patients presenting with seizures, a normal neurologic examination, and no evidence of an active systemic disease.§CT or MRI showing hydrocephalus or abnormal enhancement of the leptomeninges, and myelograms showing multiple filling defects in the column of contrast medium.\Seizures, focal neurologic signs, intracranial hypertension, and dementia.¶Histologically confirmed subcutaneous or muscular cysticercosis, plain X-ray films showing “cigar-shaped” soft-tissue calcifications, or direct visualization of cysticerci in the anterior chamber of the eye.**The presence of two different lesions highly suggestive of neurocysticercosis on neuroimaging studies should be considered as two major diagnostic criteria. However, positive results in two separate types of antibody detection tests should be interpreted only on the basis of the test falling in the highest category of diagnostic criteria.
