Revised degrees of certainty for the diagnosis of neurocysticercosis

Diagnostic certaintyCriteria
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.
Definitive1. Presence of one absolute criterion
2. Presence of two major plus one minor and one epidemiologic criterion
Probable1. Presence of one major plus two minor criteria
2. Presence of one major plus one minor and one epidemiologic criterion
3. Presence of three minor plus one epidemiologic criterion
