KAEN, A. et al. Intradural extramedullary spinal hydatidosis: case report. Neurocirugía [online]. 2009, vol.20, n.3, pp.282-287. ISSN 1130-1473.

The parasitic tapeworm Echinococcus granulosis causes hydatid disease, which is rarely encountered in nonendemic regions. It is a progressive disease with serious morbidity risks. Rarely, these cysts are found in the spine. They are mainly found epidurally, originating from direct extension from pulmonary, abdominal or pelvic infestation. Nevertheless, the main mechanism for intradural involvement is not yet clear. Antihelminthic treatment should be administered for a long period following early decompressive surgery. We report a case of recurrent hydatid disease that presented unusual intradural dissemination. Prognosis for spinal hydatid disease remains very poor and comparable to that of a malignant neoplasm.

Keywords : Hydatid cysts; Intradural; Spine; Echinococcus.
