The authors make general considerations about the clinical picture and prognosis of cerebral cysticercosis and relate a case with favorable evolution for 10 years, which had a complete cure. The patient, a 5 year old girl, was first seen due to repeated Jack-sonian seizures. She had been healthy but had had tape-worm. Craniogram was normal, and spinal fluid examination revealed hypercytosis, with eosinophils, increased proteins, particularly the globulins, and positive reaction for cysticercosis. The patient was carefully re-examined during these 10 years, and clinical examinations and spinal fluid tests were performed every six months. She received general anti-epileptic treatment (hidantoinate and barbiturate) and specific treatment for cysticercus. The seizures disappeared after 2 years of treatment, with a slight recurrence in 1948, and the spinal fluid examinations showed progressive decrease in the cell count, normalization of proteins and the reaction for cysticercus became negative. The craneogram, which was normal beforei now showed four calcified cysticercus. The EEG made in 1953 showed no evidence of focal lesion. The somatic and mental development of the patient was normal.
