“…Rajabi et al (2013) reported orbital hydatid cysts with diverse localities in extraconal, medial rectus, intraconal space, lacrimal gland, and intraosseous of the orbital wall (14). Bagheri et al (2010) showed two different presentations of orbital echinococcosis due to hydatid and alveolar cysts in Iranian patients (15).…”

Introduction: The orbital hydatidosis due to Echinococcus granulosus accounts for only less than 1% of all hydatid cysts. Here we report a case series of intraorbital hydatid cysts. Case Presentation: This retrospective investigation included two pediatric patients (4 and 13-year-old boys) who were referred because of a progressive proptosis in northwest Iran. Orbital imaging disclosed cystic intraorbital lesions in the cases. Following clinical and surgical explorations, the histopathological evaluation re-confirmed definitely the infertile unilocular hydatid cysts. Conclusions: Differential diagnoses of orbital hydatid cysts from cystic lesions should be explicitly noticed in endemic areas prior to surgery in order to avoid complications.

“…En diversas publicaciones, las lesiones tumorales quísticas de la órbita en niños, de etiología inflamatoria, están asociadas a infecciones parasitarias, siendo la más frecuente la hidatidosis (8) . En nuestro medio, la infección sistémica por hidatidosis en niños es frecuente y ha sido ampliamente reportada en trabajos epidemiológicos.…”

Los tumores quísticos primarios de la órbita, causados por infestaciones parasitarias como el Equinococcus granulosus son raros. Al ser el Perú zona endémica para este parásito, presentamos el caso de una niña de 10 años de edad, proveniente de una zona rural de Huancavelica, con proptosis axial irreductible del globo ocular derecho, de curso progresivo, con pérdida de la agudeza visual e imágenes tomográficas de la órbita en relación a masa tumoral de apariencia quística. Los exámenes serológicos fueron negativos, la paciente fue sometida a resección quirúrgica con resultado histopatológico de membranas anhistas correspondientes a quiste hidatídico. Al año de seguimiento no se evidencia recurrencia local ni sistémica. En conclusión, ante una tumoración orbitaria quística en pacientes pediátricos, se debe de considerar como diagnóstico diferencial la hidatidosis orbitaria, sobre todo si proceden de zonas endémicas.Palabras clave: Órbita; Tumor; Neoplasias orbitárias; Equinococcus granulosus; Equinococosis; Zoonosis (fuente: DeCS BIREME). PRIMARY ORBITAL CYSTIC TUMOR: A CASE OF HYDATIDOSIS IN A CHILD ABSTRACTPrimary orbital cystic tumors caused by Echinococcus granulosus are rare. As this parasite is endemic in Peru, we report the case of a 10-year-old girl from a rural area of Huancavelica, who presented with progressive and irreducible axial proptosis of the right eye and loss of vision. Orbital tomographic images demonstrated a tumor mass with a cystic appearance. Serologic tests were negative. The patient underwent surgical resection, and histopathologic analysis revealed anhistic membranes, corresponding to hydatid cysts. During one year of follow-up, no evidence of local or systemic recurrence was observed. In conclusion, orbital hydatidosis should be considered in the differential diagnosis of a cystic orbital tumor in pediatric patients, especially if the patient is from an endemic area. Key words.

INTRODUCCIÓNLas lesiones quísticas de la órbita pueden clasificarse según su relación con las estructuras adyacentes, por el tiempo de aparición, la etiología, o por el tipo de células que constituyen su pared, siendo estos de difícil diagnóstico debido a su similitud en sus características clínicas y radiológicas. Según su etiología, estos pueden ser traumáticos, quirúrgicos, inflamatorios e idiopáticos (1) . Las lesiones orbitarias de tipo quísticas inflamatorias son raras en la mayor parte del mundo, aunque relativamente más frecuentes en zonas tropicales, causados, principalmente, por infecciones por Echinococcus granulosus y el cisticerco de Taenia solium (1,2) . La hidatidosis es una zoonosis parasitaria asociada, principalmente, a la especie Echinococcus granulosus (2) . El quiste hidatídico puede localizarse en distintos tejidos, siendo los más frecuentes el tejido hepático (70%) y pulmonar (20%) (3) . La presentación orbitaria es inusual y representa, aproximadamente, 1 a 2% de los quistes hidatíd...

“…Orbital involvement is rare, and the most common symptoms in orbital hydatid cyst are slowly progressive unilateral proptosis, with or without pain, visual deterioration with or without optic disc edema, periorbital pain, headache, and disturbance in ocular mobility 263–265. Ultrasonography, computed tomography, and magnetic resonance imaging are diagnostic imaging techniques.…”

Different forms of optic neuropathy causing visual impairment of varying severity have been reported in association with a wide variety of infectious agents. Proper clinical diagnosis of any of these infectious conditions is based on epidemiological data, history, systemic symptoms and signs, and the pattern of ocular findings. Diagnosis is confirmed by serologic testing and polymerase chain reaction in selected cases. Treatment of infectious optic neuropathies involves the use of specific anti-infectious drugs and corticosteroids to suppress the associated inflammatory reaction. The visual prognosis is generally good, but persistent severe vision loss with optic atrophy can occur. This review presents optic neuropathies caused by specific viral, bacterial, parasitic, and fungal diseases.
