Hydatidosis is a disease caused by the larval stage of Echinococcus, the most prevalent species being Echinococcus granulosus. Hydatidosis is endemic to Eurasia, Africa, Australia and South America. In Chile, it has a reported incidence of 2.1 cases per 100,000 inhabitants and, although it is associated with the livestock areas of southern Chile, there have been reports throughout the territory due to the displacement of the population and its long incubation period. It is characterized by the presence of a cyst usually at the hepatic (75%) or pulmonary (15%) level. The involvement of other regions is less common and bone involvement is a rarity that does not exceed a 1-2.5% prevalence, either in the trabecular tissue or spinal canal. A combined medical and surgical approach is the most common treatment which involves disparate clinical outcomes due to the high rate of recurrences and sequelae. Experience in the management of patients with intraspinal hydatidosis is limited because of their low frequency. Therefore, we wanted to report 2 cases treated in our center and to analyze the progress in its management.
