Article information

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.

Hydatid cysts

El Equinococcus granulosis es el parásito causante de la hidatidosis, que se encuentra de forma muy poco frecuente en regiones no endémicas. Es una enfermedad quística progresiva con riesgo de causar morbilidad importante, afectando principalmente al hígado y al pulmón. Muy raramente se encuentran quistes a nivel espinal. La hidatidosis espinal afecta sobre todo al espacio epidural por extensión directa de infección existente a nivel pulmonar, abdominal o pélvico. No obstante, el mecanismo para la afectación intradural todavía no está aclarado. El tratamiento antihelmíntico ha de ser administrado durante largo tiempo tras la cirugía descompresiva. Presentamos el caso de una hidatidosis espinal recurrente que presentó una diseminación intradural inusual. El pronóstico de la hidatidosis espinal continúa siendo muy pobre, comparable al de una enfermedad neoplásica maligna.
