Usefulness of concentrated CSF hemagglutination technique for the diagnosis of cerebral cysticercosis.

Determinations were made in concentrated CSF immunoglobulins in two groups of patients with different neurological problems and in patients with surgically confirmed diagnosis of CNS cysticercosis. Antibody vs. cysticercus antigen determinations were also made in concentrated CNS by means of indirect hemagglutination as a procedure to establish CNS cysticercosis. Positive results were obtained in 68 per cent of surgically confirmed cysticercosis. This procedure seems to be more sensitive for CNS cysticercosis diagnosis.
