Neurocysticercosis--a comprehensive approach to medical treatment.

The incidence of cysticercosis in South Africa may well be alarming. Cysticercosis of the central nervous system (CNS) is almost exclusively confined to the parenchyma of the brain. Before the introduction of computed tomography (CT), invasion of the CNS by the parasite could only be suspected on the basis of evidence of previous infestation. The use of praziquantel in the treatment of cysticercosis is a major step towards eradicating the disease, but to be effective treatment must take cognizance of reinfection, the allergic reaction caused by the dying parasites, and the possible need for repeated courses of treatment. The therapeutic regimen is outlined and the efficacy of the treatment as monitored by CT evaluated.
