These results differ from those reported in most studies about praziquantel or albendazole therapy for parenchymal neurocysticercosis (NC)2-10 and did not match with those previously reported by the same authors in the same population of patients with NC. In 1988, Carpio et al11 described 20 patients with parenchymal NC in whom albendazole was highly effective and caused a 84% reduction in the number of brain cysts.
