Nuestra conducta frente a los quistes hidatídicos primarios del páncreas / Our experience with pancreatic primary cysts

Antecedentes: Los quistes hidatídicos primarios pancreáticos son raros por no decir excepcional, siendo en las grandes series su incidencia apenas entre el 0,2 % al 0,3%. Lugar de Aplicación: Servicio de Cirugía General "Pablo Luis Mirizzi" del Hospital Nacional de Clínicas, Sanatorio Allende y Clínica Privada Caraffa de Córdoba. Diseño: Cooperativo, retrospectivo. Material y Método: Entre diciembre de 2000 y diciembre del 2019 han sido tratados quirúrgicamente 9 pacientes con hidatidosis primaria de páncreas, siendo 5 del sexo masculino y los cuatro restantes del sexo femenino, con una edad promedio de 39,4 años. En relación con la clínica, todos los pacientes tenían dolor abdominal, acompañado de vómitos, distensión abdominal y fiebre. En tres presentaban una masa abdominal palpable. A todos se les solicito laboratorio y pruebas de hidatidosis, destacándose en 6 de los 9 pacientes dieron positivo. Resultados: Se estudiaron a todos los pacientes con una ecografía abdominal, TC de abdomen y en un paciente una CPRMN más RMN de abdomen. Se realizaron previamente el tratamiento con abendazol antes del tratamiento quirúrgico en todos los casos. En relación con el tratamiento quirúrgico, se llevó a cabo el destechamiento y drenaje del quiste con la técnica de Mabit-Lagrot en 6 oportunidades y en 3 con la Técnica de Goinard. Conclusión: La localización de los quistes hidatídicos en el páncreas es rara. El diagnóstico se basa fundamentalmente en los estudios por imágenes, además si se correlacionan con la epidemiología y la serología hidatídica positiva. El tratamiento del quiste hidatídico de páncreas es quirúrgico.

Background: Pancreatic primary hydatic cysts are rare not to say exceptional, with their incidence in large series being only 0.2% to 0.3%. Setting: General Surgery Service "Pablo Luis Mirizzi" of the National Hospital of Clinics, Allende Sanatorium and Caraffa Clinic of Córdoba. Design: Retrospective and cooperative. Methods: Between December 2000 and December 2019, 9 patients with primary pancreatic hydatic have been treated surgically, with 5 of the male sex and the remaining four of the female sex, with an average age of 39.4 years. In relation to the clinic, all patients had abdominal pain, accompanied by vomiting, bloating and fever. In three they had a palpable abdominal mass. All were asked for laboratory and hydatic tests, highlighting in 6 of the 9 patients tested positive. Results: All patients with abdominal ultrasound, abdominal CT and a patient were studied for CPRMN plus MRI of the abdomen. Abendazole was previously treated prior to surgical treatment in all cases. In relation to surgical treatment, the traditional unroofing and drainage of the cyst was carried out with the Mabit-Lagrot technique in 6 opportunities and in 3 with the Goinard Technique. Conclusions: The location of hydatic cysts in the pancreas is rare. Diagnosis is based primarily on imaging studies, in addition if they correlate with epidemiology and positive hydatic serology. Treatment of the pancreas hydatic cyst is surgical

Quiste hidatídico intracardíaco en una niña: Reporte de caso / Cardiac Hydatid Cyst in a Child: A Case Report

RESUMEN La equinococosis es una infección parasitaria provocada por Echinococcus granulosus, que, en su estado quístico, forma al denominado quiste hidatídico. Presenta morbilidad importante, con posibles secuelas relacionadas con la ubicación, y altos costos debido al tratamiento quirúrgico y farmacológico prolongado. El hígado y el pulmón son las ubicaciones anatómicas más usuales, mucho más raras son el riñón, bazo, cerebro y corazón, este último representa el 0,5 % a 2 % del total de casos. El Perú es un país endémico de esta antropozoonosis y principalmente registra casos procedentes de la sierra central (95 %). Se presenta el caso de una niña de diez años, con diagnóstico de esta entidad, clasificación ecográfica CE 1, grupo clínico 1 (confirmado por anatomía patológica) con posterior tratamiento quirúrgico y farmacológico específico (albendazol). La paciente se recuperó satisfactoriamente de la cirugía practicada, y fue dada de alta a los 16 días, sin complicaciones.

ABSTRACT Echinococcosis is a parasitic infection caused by Echinococcus granulosus, which, in its cystic state, forms the socalled hydatid cyst. It presents important morbidity, with possible sequelae related to the location, and high costs due to surgical and prolonged pharmacological treatment. The liver and the lung are the most common anatomical locations, and much rarer are the kidney, spleen, brain, and heart, where the latter represents 0.5 to 2% of total cases. Peru is an endemic country of this anthropozoonosis and mainly records cases in the central highlands (95%). This paper presents the case of a 10-year-old girl, diagnosed with this disease, CE1 ultrasound classification, clinical group 1 (confirmed by pathological anatomy) with specific surgical and pharmacological treatment (albendazole) afterward. The patient recovered satisfactorily from the surgery and was discharged at 16 days, without complications.

Evaluación del gasto económico en la atención de hidatidosis humana en Junín, Perú / Evaluation of economic expenditure related to human hydatidosis in Junín, Peru

RESUMEN El objetivo del presente estudio fue determinar la pérdida económica que ocasiona el tratamiento de la hidatidosis humana, para lo cual se realizó un análisis de costos de los casos reportados en la región Junín en Perú, durante el año 2013. El costo total (directo e indirecto) en dólares americanos por paciente atendido por el Ministerio de Salud (Minsa) fue USD 1 220,0; por el seguro social (EsSalud) fue USD 3 051,0 y por la atención privada fue USD 4 090,7. La pérdida media anual según el número de atenciones por hidatidosis humana no complicada fue USD 24 542,0 en el Minsa, USD 369 292,0 en EsSalud y USD 130 566,4 en la atención privada. Las pérdidas de productividad humana constituyen la minoría. Nuestros hallazgos indican que la hidatidosis impone una pesada carga económica en la región Junín.

ABSTRACT The objective of the present study was to calculate the economic loss caused by the treatment of human hydatidosis. For this purpose, a cost analysis of the cases reported in the Junin region of Peru in 2013 was conducted. The total cost (direct and indirect) per patient assisted by the Ministry of Health (Ministerio de Salud-Minsa), the social security system (EsSalud), and private health care was 1,220, 3,051, and 4,090 US dollars (USD), respectively. The mean annual loss considering the number of health care services for uncomplicated cases of human hydatidosis was USD 24,542 in Minsa, USD 369,292 in EsSalud, and USD 130,566 in private health care. Overall, the rate of loss of human productivity was a small proportion. Our findings indicate that hydatidosis imposes a heavy economic burden in the Junin region of Peru.

Primary pelvic hydatid cyst in a postmenopausal female: a surgical challenge

Primary pelvic hydatid cysts are a rare entity and are often overlooked as a differential diagnosis of a pelvic-space-occupying lesion particularly in non-endemic regions. Unpreparedness and a hasty decision on the surgical approach may end in life-threatening complications and systemic dissemination of the disease. We report the case of a 55-year-old postmenopausal woman with a history of two previous unsuccessful surgeries to remove pelvic cystic lesions due to dense adhesions between the surrounding gut wall, bladder, and the cyst wall. Clinical and imaging findings failed to diagnose the nature of the cysts, and a laparotomy was contemplated. On the third surgical attempt, the clinical suspicion was considered and by meticulous dissection the cysts were removed thoroughly without undue complications. In the postoperative follow-up period there was no sign of disease recurrence or dissemination.

Hidatidosis en niños: experiencia en un hospital de alta complejidad fuera del área endémica / Echinococcosis in children: Experience in a tertiary care hospital outside the endemic area

La hidatidosis es una zoonosis con una amplia distribución en Argentina y en el mundo. Se adquiere en la infancia, pero se presenta, más frecuentemente, en la edad adulta. La población pediátrica representa el 10%-20% del total de los casos. Se presentan 47 niños con diagnóstico de hidatidosis durante un período de 20 años. La mediana de edad fue de 8 años (rango: 3-17) y, en su mayoría, tenían algún antecedente epidemiológico orientador, como la procedencia de un área endémica, rural y/o la tenencia de perros alimentados con visceras. El 85% fueron quistes únicos localizados en un solo parénquima. Las localizaciones quísticas pulmonares y hepáticas fueron las más frecuentemente encontradas. El tratamiento fue médico-quirúrgico en 45 pacientes (96%). Trece (28%) presentaron alguna complicación posterior, que fue más frecuente en aquellos con localización pulmonar. Tres (6%) recayeron entre el mes y los 24 meses, y requirieron una nueva cirugía. Ninguno falleció a causa de la enfermedad parasitaria.

Echinococcosis is a zoonotic disease that is widely spread across Argentina and worldwide. It is acquired during childhood but it is more common during adulthood. The pediatric population accounts for 10-20% of all cases. This study included 47 children diagnosed with echinococcosis over a 20-year period. Their median age was 8 years old (range: 3-17); most patients had some epidemiological history, such as having lived or living in an endemic or rural area and/or having dogs that are fed with viscera. Findings included 85% of single cysts in only one parenchyma. Cysts were most commonly located in the liver and lungs. Medical/surgical treatment was carried out in 45 patients (96%). Subsequent complications were observed in 13 patients (28%), which were more common in those with lung cysts. Three patients (6%) relapsed 1-24 months later and required a new surgery. No patient died as a result of the parasitic disease.

Diagnóstico, tratamiento y seguimiento de la hidatidosis / Diagnosis, treatment and monitoring of hydatid disease

En el año 2003 el grupo de trabajo de la OMS sobre la equinococosis (WHO-IWGE) publicó una clasificación ecotomográfica que monitorea su historia natural. Esta se traduce en el paso de un quiste simple a una etapa de transición, la cual finaliza con su inactivación. Basándose en esta clasificación y ante la carencia de criterios uniformes en el manejo de esta enfermedad en el país, el grupo de trabajo de la región de Aysén decidió proponer un manejo integral de esta zoonosis, la cual fue aceptada y publicada como normas por el Ministerio de Salud en enero del 2016. El objetivo de este documento es dar a conocer las normas en el diagnóstico, tratamiento y seguimiento de los pacientes portadores de hidatidosis basado en las normas ministeriales.

In 2003 the Working Group on Echinococcosis WHO (WHO-IWGE) published a classification ecotomographic monitors its natural history. This results in the passage from a simple cyst to a transitional stage which ends with its inactivation. Based on this classification and in the absence of uniform criteria in the management of this disease in the country, it is that the working group of the Aysen Region decided to propose an integrated management of this zoonosis, which was accepted and published as Standards for the Ministry of Health in January 2016. The purpose of this paper is to present standards in the diagnosis, treatment and monitoring of patients with hydatid disease based on ministerial standards.

Cisto hidático do rim: tratamento médico / Renal hydatid cyst: medical treatment

Resumo Introdução: A infecção por Echinococcus ou hidatidose constitui-se em uma zoonose causada pelo parasita Echinococcus granulosus. Apresenta distribuição mundial, sendo Portugal considerado endêmico. A doença hidática do rim é rara, ocorrendo em apenas 2% dos casos. Caso Clínico: Adolescente de 14 anos, do sexo masculino, com doença hidática do rim. O diagnóstico foi efetuado por exames de imagem e por teste sorológico específico. Foi instituída terapêutica com albendazol durante quatro ciclos de quatro semanas cada, tendo-se verificado diminuição significativa do tamanho do cisto e negatividade dos anticorpos específicos. Discussão: Embora a terapêutica recomendada seja a excisão cirúrgica, estudos demonstram que a terapêutica médica pode ser uma alternativa a considerar, permitindo a preservação do órgão.

Abstract Introduction: Hydatid disease is a zoonosis caused by the parasite Echinococcus granulosus. It has a worldwide distribution, being endemic in Portugal. Hydatid disease of the urinary tract is rare, occurring in less than 2% of all cases. Case report: 14-year-old male with hydatid disease of the kidney. The diagnosis was established by imaging studies and specific serologic testing. Treatment consisted of four 4-week cycles of albendazol and resulted in a progressive reduction of the cyst as well as in a negative specific serology. Discussion: Even though the recommended treatment is surgical excision, studies have demonstrated that medical treatment may be an alternative allowing for organ preservation.

Hydatid cysts in muscles: clinical manifestations, diagnosis, and management of this atypical presentation

ABSTRACTINTRODUCTION: Hydatid cysts are rarely detected in muscle tissue (0.7-0.9%), even in endemic countries. The aim of this study was to present information regarding the clinical manifestations, diagnosis, and management of muscle echinococcosis.METHODS: Twenty-two patients with hydatid cysts in the muscle were followed from January 2006 through December 2014.RESULTS: Twenty-four sites of muscle involvement were observed in the 22 patients. Fifteen (68%) of our patients were women, while seven (32%) were men. The mean age was 28.1 ± 15.4 (6-61) years. The most frequent locations were the thigh (27.2%) and the paravertebral region (13.6%). Most patients reported a painless slow-growing mass with normal overlying skin. Most (90.2%) cases were treated by surgical excision and fine-needle aspiration.CONCLUSIONS: Primary muscle hydatid cyst should be considered in the differential diagnosis in cystic masses of the muscular system without pain and localized enlargement of soft tissue, especially in endemic areas. Hydatid cyst should be investigated using serological tests and imaging modalities. If possible, total surgical excision of hydatid cyst in the muscle should be performed.

Interventricular septal hydatid cyst: Transesophageal echocardiography as a therapeutic tool during bypass.

Cystic echinococcosis (hydatid disease) arising from infestation with a larval or adult form of the Echinococcus granulosus tapeworm is endemic in certain states of India, but affecting interventricular septum (IVS) solitarily is a scarce phenomenon. We present a rare case of transesophageal echocardiography guided management of IVS hydatid cyst even during cardiopulmonary bypass, which presented with a rather unusual complaint of repeated syncope.

Estimación del impacto económico de la equinococosis quística en Chile y análisis de las posibles causas que han dificultado su erradicación / Estimation of costs caused by cystic echinococcosis

Background: Hydatid disease or cystic echinococcosis, caused by the parasite Echinococcus granulosus, has a worldwide distribution, affecting people of working age and can cause high levels of morbidity and even death. Aim: To estimate the economic impact at the human and animal level caused by the disease in Chile. Material and Methods: We analyzed information about the disease obtained from reports and publications emanated from the Chilean Ministry of Health, United Nations Food and Agriculture Organization, the U.S. National Institute of Statistics and the National Agricultural Service. Animal derived costs were estimated evaluating the expenses for pharmacological treatment of infected dogs and animal production losses derived from confiscations and reductions in meat production. Results: The total number of patients who underwent surgery to remove a hydatid cyst in Chile during 2012, was estimated as 767 individuals. The annual costs derived only from surgical treatment, were estimated in USD 2.46 million. Summing the costs of sick leaves and loss of productivity, the costs at the human level ascended to USD 3.13 million. Considering human and animal costs, the annual economic burden of the disease was estimated in USD 14.35 million. Conclusions: The Analysis of the regional distribution of human and animal hydatidosis, suggests a significant environmental contamination with parasite eggs in high incidence regions such as Aysén, Araucanía, BioBío and Coquimbo. The efficiency of control programs for the disease would be greatly improved if the causes for these regional contaminations are elucidated.

Hydatid cyst of the left ventricle of the heart

The present study involves a 47-year-old male patient from Jordan that presented with a history of progressive shortness of breath and chest tightness. Cardiac hydatidosis was diagnosed based on typical radiological findings and a positive serology test. Intra-operatively, there was a mass of a hydatid cyst located in the left ventricle and interventricular septum with no other organs involved. The patient was treated by a surgical excision and albendazole without any complications

Hydatid cyst of the knee: a case report

Hydatid disease is a parasitic infection which occurs in specific geographical areas such as the Mediterranean region. We report a case of hydatid cyst of the knee in a 34-year-old man who was admitted with inability to walk and a painful knee. He had a past history of liver infection nine years ago. Laboratory findings were negative. According to the high prevalence of hydatid disease in Iran, it should be considered as a differential diagnosis of Baker's cyst, synovial cyst and lipoma

Quiste hidatídico retro-peritoneal: Una enfermedad frecuente en una ubicación inusual / Retroperitoneal hydatid cyst: A common disease in a rare location

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.

Quiste hidatídico primario de bazo / Primary hydatid cyst of the spleen

Paciente varón de 63 años, natural y procedente de Lima. Ha estado en área ganadera hace 7 años. Su enfermedad fue insidiosa y progresiva, un mes antes del ingreso tuvo malestar y distensión abdominal, asociado a náusea y vómito ocasionales; no presentó pérdida de peso. En el examen clínico estaba lúcido y estable; no tenía ictericia. El abdomen era blando sin signos de irritación peritoneal; en el hemiabdomen izquierdo se palpaba una masa grande de límites definidos, no dolorosa, adherida a planos profundos. Resto del examen no tuvo alteraciones significativas. Exámenes auxiliares: Hemograma: Normal, eosinófilos 5.74%; examen de orina, perfil de coagulación, bioquímica y electrolitos sin alteraciones. Proteínas totales, albúmina, bilirrubinas Y transaminasas y fosfatasa alcalina sin alteraciones significativas. Arco V positivo: 248 (N < 22 ) e inmunoblot para Echinococcus granulosus positivo. La ecografía abdominal mostraba 'dos' formaciones quísticas tabicadas de 161 x 95 mm y 146 x 130 mm, que desplazaban bazo y riñón izquierdo. La tomografía axial computarizada fue interpretada como una gran formación ovoide (12 x 18 x 27 cm) dependiente de bazo, lobulada, hipodensa con áreas focales redondeadas de menor atenuación a predominio periférico y septos internos, sin realce al contraste endovenoso, compatible con quiste hidatídico Gharbi III. Intervenido quirúrgicamente se encontró un quiste hidatídico esplénico gigante: biloculado, tabicado, que ocupaba hipocondrio y flanco izquierdo de abdomen, tenía paredes gruesas, vesículas hijas y liquido claro en su interior. La lesión quística estaba adherida al colon descendente, estómago y hemidiafragma izquierdo. Se realizó quistectomía parcial mas drenaje externo; no presentó complicaciones posquirúrgicas. Presentamos este caso porque el quiste hidatídico esplénico (primario) es poco frecuente, menos aún como localización única, se reporta que su prevalencia no supera el 1%.

We present the case of a 63 year male patient, natural from Lima. He has been in a cattle zone seven years ago. His illness had an insidious start and a progressive course; from a month ago he had malaise associated with nausea, abdominal distention and occasional vomiting; denies weight loss. In the clinical examination was lucid and stable, and without jaundice. The abdomen was soft without signs of peritoneal irritation; in the left flank there was a large mass with defined limits, painless, attached to deeper layers. Auxiliary tests: CBC: eosinophils 5.74%; the levels coagulation, biochemistry and electrolytes were normal. Total protein, albumin, bilirubin levels, aminotransferasas (ALT an AST) and alkaline phosphatase were normals. Arco V: 248 (N < 22) and positive Inmunoblot to Echinococcus granulosus. Abdominal ultrasound showed two cystic formations of 161 x 95 mm and 146 x 130 mm, that moving the left kidney and spleen. Axial tomography was interpreted as a large ovoid formation (12 x 18 x 27 cm) dependent on spleen, lobed, hypodense, with rounded focal areas with less attenuation in the peripheral area; without contrast enhancement, compatible with hydatid cyst Gharbi III. The surgical intervention was a partial cystectomy plus external drainage; the surgeon found a giant splenic hydatid cyst, occupied the left hypochondrium and the left flank; had thick walls, daughter vesicles and clear liquid inside. The cystic lesion was attached to the descending colon, stomach, and left diaphargm. We present this case because the splenic hydatid cyst is rare, even less as a single site, and their prevalence does not exceed 1%.

Hidatidosis poliquística tropical por Echinococcus vogeli / Polycystic tropical echinococcosis due to Echinococcus vogeli

Antecedentes. Hace 30 años se reconoció que las tumoraciones poliquísticas en 13 pacientes autóctonos de países tropicales sudamericanos eran producidos por una nueva especie de parásitos, el Echinococcus vogeli. Ahora se conocen 200 casos en 12 países (desde Panamá hasta Brasil y Perú). Lugar. Cali, Colombia; Nueva Orleans y Seattle, USA. Diseño. Estudio experimental y retrospectivo. Objetivo. Se presenta esta enfermedad a países con zonas tropicales donde la enfermedad aún es desconocida. Métodos. Se estudiaron 78 pacientes. El curso fue crónico, de quistes abdominales, algunos dolorosos, hepáticos, con o sin cirrosis biliar, asociados a lesiones torácicas y mesentéricas. El 85% se localizó en el hígado y el 14% en el pulmón. El diagnóstico se basó en el examen físico, la radiología, la procedencia rural, el conocimiento de la paca, en la convivencia con perros y en la serológica. Conclusiones. El tratamiento se basa en la cirugía y el albendazol. La equinococosis poliquística tropical por el Echinococcus vogeli representa un problema médico severo en América del Sur, con mortalidad del 29%. Los casos diagnosticados representan una pequeña proporción de las infecciones humanas.

Background. Thirty year ago it was recognized experimentally that polycystic tumors in 13 autochthonous patients from south American countries were produced by a new species: Echinococcus vogeli. As of march 2007, 200 cases were known from 12 countries (from Panamá, Colombia and Venezuela to Brasil and Perú). Places. Cali, Colombia; New Orleans and Seattle, USA. Design. Experimental and retrospective studies. Objective. This disease is presented to the countries with tropical areas, where the illness is steel unknown. Methods. 78 patients were studied. They had cysts, sometime painful, connected with the liver, with or without biliar cirrhosis, associated with pulmonary and mesenteric lesions. 85% in the liver, 14% in the lung. The diagnosis was based in palpation, radiological imaging, rural origin, knowledge of the paca, history of closed contact with dogs and positive serology for echinococcosis. Conclusions. The combination of surgery and albendazol was the most efficient treatment. The tropical polycystic echinococcosis is a severe medical problem in South America with a 29% mortality. The number of diagnosed cases probably only represent a small proportion of the human infections.

Hidatidoses humanas / Human hydatidoses

A hidatidose é uma infecção ciclozoonótica causada pela tênia Echinococcus granulosus. A forma larvária pode ser encontrada em diversos órgãos humanos, principalmente no fígado e pulmões. A distribuição da parasitose está diretamente relacionada à presença de canídeos portadores, que disseminam os ovos, contaminando o ambiente. O diagnóstico é clínico, podendo ser complementado com métodos de imagem e de investigação laboratorial - sorológicos, parasitológicos e de biologia molecular. O tratamento da hidatidose é predominantemente cirúrgico, através da extirpação do cisto. No tratamento farmacológico emprega-se o mebendazol e o albendazol.

Hydatidosis is a cyclozoonotic infection caused by taenia Echinococcus granulosus. The larva form can be found in various human organs, mainly the liver and the lungs. The distribution of the parasite is directly related to the presence of dogs carrying the disease, which disserminate the eggs, contaminating the environment. The diagnosis is clinical, it can be complemented with images and laboratorial exams. The treatment of hydatidosis is mainly surgical with the extraction of the cyst. In the pharmacological treatment mebendazol and albendazol are used.

Hidatidosis uterina: una localización excepcional / Uterine hydatid cyst: an exceptional location

La hidatidosis es una zoonosis de distribución mundial producida por helmintos del género Echinococcus. En Chile representa un problema de salud pública no resuelto aún en su totalidad. La localización ginecológica es poco frecuente, pero debe considerarse en el diagnóstico diferencial de masas pélvicas, sobre todo, en pacientes con infertilidad. Se presenta un caso clínico de hidatidosis pélvica primaria de origen uterino como hallazgo operatorio. Se discute el manejo y seguimiento.

The hydatid disease is a worldwide distribution zoonotic infection caused by a tapeworm of the genus Echinococcus. In Chile, it is a public health probiem that hasn't been completely solved yet. It is very unlikely to be found in ginecology. Still it has to be considered within pelvic mass study, mostly between infertile patients. We now discuss a surgical finding of a pelvic primary hydatid disease of uterine origin clinical case, the management and follow-up.
