ABSTRACT
Echinococcal disease remains a major problem within some endemic areas. We report a case of a single primary echinococcal cyst located in the retroperitoneal space. A 54-year-old woman, born in a rural area of southern Chile, was admitted with a 3-month history of right hip pain and painful swelling of the gluteal region. Hidatid disease was confirmed with serologic test, radiological examinations and histo-pathology. There were no cysts in any other location. A percutaneous drainage was performed and antihelminthics were administered for 12 weeks and is now being closely followed up, with good response to therapy. Especially in the endemic areas hydatid cyst should be considered when evaluating retroperitoneal cystic masses.
La hidatidosis sigue siendo un problema prevalente en áreas endémicas. Presentamos el caso de un quiste hidatídico primario ubicado en el espacio retro-peritoneal. Mujer de 54 años, procedente de área rural del sur de Chile, hospitalizada por cuadro de coxalgia derecha y aumento de volumen glúteo, con tres meses de evolución. Se realizó el diagnóstico de hidatidosis complicada por medio de exámenes de imágenes, tests serológicos y anatomía patológica. No se demostraron quistes hidatídicos en otras ubicaciones. Se realizó un drenaje percutáneo del quiste infectado y se administraron antihelmínticos durante 12 semanas y actualmente permanece en seguimiento cercano con buena respuesta al tratamiento. El quiste hidatídico debe ser considerado en el diagnóstico diferencial de masas quísticas retro-peritoneales, especialmente en áreas endémicas.

Hydatid disease is one of the commonest parasitic infections of the liver, rupture of which into the peritoneal cavity leads to secondary echinococcosis. Seventy percent of hydatid disease cases occur in the liver, although any organ may be involved. A case of omental and retroperitoneal hydatid disease along with the hydatid cyst of the liver is present
