It is reported the case of a 57 years-old man from Maranhão State who presented Parkinson's syndrome. Images proper to calcified cysticerci were found in the basal ganglia at the CT-scan examination. Considerations are made as to: the low frequency of cysticercosis in the northern region of the country where the patient lives; the association of symptomatic Parkinson's syndrome and cysticercosis of the central nervous system, which is rare; the demonstration of calcified cysticerci in basal ganglia in this situation, which was not registered up to the present time.
