[Anesthetic management of sacroiliac-vertebral echinococcosis].

Bone echinococcosis affects the spine and pelvis in 60% of cases. Bone lesions may be silent for between 10 and 20 years. The capsules progress aggressively through the medullary canal and replace the trabecular bone without forming cysts, as occurs in the organs, thus making anaplylaxis rare. The combination of chemotherapy and surgery facilitates anesthetic management and reduces the incidence of anaphylactic events and disease recurrence.
