Hidatidosis vertebral: a propósito de un caso / Vertebral hydatidosis: case report

La hidatidosis causada por el echinococcus granulosus puede afectar cualquier órgano del cuerpo siendo el pulmón y el hígado los más comúnmente afectados. El compromiso vertebral por el echinococcus granulosus es de escasa prevalencia, comprendiendo con menos de 1% del compromiso óseo. Presentamos el caso de una mujer de 50 años que consultó en Servicio de Traumatología por cuadro de dolor lumbar progresivo, de cinco meses de evolución, irradiado a extremidad inferior derecha y posterior compromiso neurológico de extremidad. El estudio imagenológico reveló espondilodiscitis T12-L1 que posterior a estudio de biopsia confirmó este cuadro. El tratamiento es mixto, tanto ortopédico como quirúrgico. El nivel de recurrencia es alto, reportándose entre 30 y 40%. El objetivo de este caso es proponer diagnóstico diferencial de masa vertebral de origen desconocido y detallar el manejo de esta patología.

Hydatidosis caused by echinococcus granulosus may affect any organ in the body, with the lungs and the liver as the most commonly affected organs. Vertebral compromise resulting from echinococcus granulosus has a low prevalence and accounts for less than 1% of bone compromise. We report the case of a 50 year-old female who presented at the Trauma Service with progressive low back pain with 5 months of duration that irradiated to the right lower limb, and led to neurologic compromise of the limb. Imaging studies showed spondylodiscitis at T12-L1, confirmed by a biopsy. Treatment of this condition is both orthopedic and surgical. The recurrence rate is high, between 30 and 40%. The objective of describing this case is to propose the differential diagnosis of a vertebral mass of unknown origin and provide details as to how to manage this condition.

Presentación inusual de la hidatidosis: quiste hidatídico submandibular / Unusual hydatid disease presentation: submandibular hydatid cyst

La hidatidosis es una infección parasitaria causada por el parásito Echinococcus granulosus. Es un problema grave de salud que se encuentra con mayor frecuencia en las zonas rurales, donde la ganadería doméstica es común. La escisión quirúrgica completa es el tratamiento estándar para el quiste hidatídico. El tratamiento médico postoperatorio con antihelmínticos: albendazol o mebendazol se combinan con frecuencia con el tratamiento quirúrgico para prevenir la recurrencia de la enfermedad y la contaminación local de altoriesgo. A un que los quistes hidatídicos se presentan generalmente en el hígado y los pulmones, con menor frecuencia puede ocurrir en cualquier área del cuerpo. Lalocalización del quiste hidatídico en el área de la cabezay el cuello es extremadamente rara. Dado que esta enfermedad no suele venir a la mente del médico de atención primaria queremos llamar la atención de la posibilidad de la hidatidosis en el cuello. Por esta razón, presentamos un caso inusual de quiste hidatídico primario ubicado en la región submandibular del cuello en una paciente mujer de 21 años de edad...

Hidatidosis multiorgánica con compromiso peritoneal: reporte de un caso y revisión de la literatura / Multi-organ hydatidosis with peritoneal involvement: a case report and literature review

La hidatidosis es una parasitosis cuyo agente etiológico es el céstodo del género Echinococcus, siendo las especies más frecuentemente involucradas la E. granulosus y E. multilocularis. Puede afectar a cualquier órgano, aunque con mayor frecuencia se asocia a compromiso hepático y pulmonar. Los hallazgos imagenológicos clásicos en órganos habitualmente comprometidos están ampliamente descritos, no así en localizaciones poco comunes. Presentamos un caso de hidatidosis multiorgánica con compromiso peritoneal y pericárdico, estudiado con ultrasonido y tomografía computada, con revisión de la literatura actualmente disponible al respecto.

Abstract. Hydatidosis is a parasitic disease whose etiologic agent is the tapeworm of the genus Echinococ-cus, the species most frequently involved being E. granulosus and E. multilocularis. It can affect any organ, but most often is associated with liver and lung involvement. The classic imaging findings in organs that are usually involved are fully described, but not so for those in unusual locations. We report a case of multi-organ hydatidosis with peritoneal and pericardial commitment, studied with ultrasound and computed tomography, with a review of the currently available literature regarding this.

Laparoscopic Management of a Hydatid Cyst of the Adrenal Gland

Hydatid disease is endemic in parts of India, yet genitourinary involvement is rare. Laparoscopic management of such cases is uncommonly reported. We present a case of an adrenal hydatid and its management by laparoscopic aspiration, instillation of scolicidal solution, and partial excision of the cyst.

Hidatidosis cerebral: aspectos clínicos e imagenológicos. Reporte de 4 casos / Brain hydatidosis: Report of four cases

In only 2% of all cases of hydatidosis, the cysts are located in the brain. We report a 12-year-old male, a 5-year-old girl and a 19-year-old female consulting for intracranial hypertension and a 13-year-old male consulting for a left hemiparesis. Imaging studies found intra-cerebral cysts with characteristics of hydatidosis in all. All lesions were completely removed surgically and the pathological study of the excised piece confirmed the diagnosis of hydatidosis.

[Cervico-facial hydatidosis. report of 17 cases]

Cervico-facial hydatid cyst is rare. It accounts for 1% of echinococcosis locations. To describe the epidemiological, clinical and therapeutic aspects of cervico-facial hydatid cysts based on our clinical experience and data in the literature. A retrospective study was made concerning 17 patients with cervico-facial hydatid cyst treated surgically over a 25-year period from 1982 to 2006. Mean patient age was 27 years [range 2-79]. Hydatid cyst localization was: cervical muscle [7 cases], thyroid gland [5 cases], parotid gland [2 cases], cervico-thoracic [1 case], larynx [1 case] and cheek [1 case]. Hydatic origin of the cyst was suspected for 6 patients [35.3%] preoperatively. Surgical treatment was used in all cases and adapted to each case. Diagnosis was always confirmed by macroscopic aspects and pathology. Hydatid cysts are rarely found in the cervico-facial region, even in highly endemic zone. The manifestation of symptoms depends on the location and the size of the cyst. Positive diagnosis can be difficult during preoperative period. Exclusively surgical treatment is indicated, ideally for total pericystic resection without rupture

Hidatidosis ósea: Reporte de 5 casos y revisión de la literatura / Bone hydatidosis: Report of five patients

Bone location of hydatid cysts occurs in 0.5 to 3 percent of all cases of hydatidosis. The most common bones involved are spine, long bones and pelvis. We report five patients with bone hydatidosis. A 24-year-old male consulting for paraparesis and numbness of lower limbs; CAT scan showed hydatid cysts located in D2, D3 and D4 vertebral bodies. A 47-year-old male consulting for a fracture of the femur; X rays disclosed multiple hydatid cysts in the femur. A 13-year-old female consulting for claudication of the right lower limb; X ray examination showed a hydatid cyst in the iliac bone. A 21-year-old women presenting with weakness of the lower limbs and voiding problems; CAT scan showed a vertebral hydatidosis and spinal cord compression. A 67-year-old female presenting with weakness of the lower limb and loss of sphincter control; CAT scan showed hydatid cysts in D4 vertebral body.

Hidatidosis de la mama: reporte de un caso / Breast hydatidosis: report of one case

We report a 27 years old female consulting for a left breast nodule. Mammography and breast ultrasound showed a nodule with anechoic content. A fine needle aspiration obtained a crystalline fluid. The nodule was excised and the pathological diagnosis of the surgical piece showed a hydatid cyst.

La hidatidosis humana tiene una tasa de incidencia nacional, notificada en el año 2004, de 2,1 x 100.000 habitantes. Su ubicación en la mama es poco frecuente. Se presenta el caso de una mujer de 27 años con un quiste hidatídico mamario diagnosticado en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez Aravena de Temuco.

Multi vesicular osseous hydatid disease of the mandible- a case report

Hydatid disease is a common and major public health issue caused by parasite Echinococcus granulosus. The highest prevalence of the parasite can be found in different parts of world like Africa, Australia, and South America. This infection can occurs in almost any part of the body. Here we present clinical, radiological, histological features and treatment of a multi vesicular osseous hydatid disease of the mandible in an Afghan 5 year old boy with a firm swelling in the right side of mandible

Multiple organ involvement with hydatid cysts

Hydatid disease is the most common infections worldwide, but it rarely involves multiple organs. Herein, a 12-year-old boy is presented, who was admitted to Children's Medical Center, Tehran University of Medical Sciences, Tehran, Iran with symptoms of irritability, sleepless, and weakness of the extremities. Patient's brain computed tomography [CT] scan with contrast media showed large multilocular cystic lesions in right temporal lobe associated with two other smaller similar cystic lesions in centrum semiovale bilaterally. Abdominal sonography revealed intestinal mesenteric and a cardiac cyst. Abdomino-pelvic CT scan showed a cyst medial to the cecum and a cortical cyst in the left kidney as well as a heart cyst. The echocardiography confirmed hydatid cysts at apical and interventricular septum. Serology test was positive for hydatid cyst. Albendazole and praziquantel were started for the patient immediately and right temporal lobe lesions were removed via neurosurgery intervention. After one month, cardiac and mesenteric cysts were operated during two separate surgeries. Pathologic findings of all cysts were compatible with hydatid cyst. Cystic hydatidosis should be suspected in any cystic mass, whilst prompt diagnosis and appropriate treatments are the keys in management of affected patients

Bony hydatid disease of superior pubic ramus with extension into pelvis and proximal thigh.

Hydatid disease is caused by the tapeworm of genus ;Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis. Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease can take place either directly through ingestion of parasite eggs from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Infestation of hydatid disease in humans most commonly occurs in the liver (55-70%), followed by the lungs (18-35%). Bone hydatidosis however is very rare,whenever it occurs; it is usually secondary to visceral involvement. We present herein a case of primary hydatid cyst involving superior pubic ramus in a 43 years male patient, which is not a common site for the occurrence of this disease. Diagnosis is usually delayed if high index of suspicion is not there. MRI is a good tool for reaching diagnoses.

Quiste hidatídico tiroideo sintomático: caso clínico / Thyroid hydatid cyst: report of one case

We report a 64 year-old male, living in a rural area, with a history of a thyroid nodule subjected to a fine needle aspiration 18 years ago. He consulted this time for a goiter associated to dyspnoea and dyspliagia. A cliest X-ray and a neck CAT scan showed a calcified nodule in the superior mediastinum of thyroidal origin, that displaced airways and blood vessels and a small thyroid nodule of uncertain origin. A thyroid scintigram showed a cold right thyroid nodule. The patient was operated, performing a subtotal thyroidectomy A calcified nodule measuríng 8x6x6 cm and another nodule measuríng 10 mm were found during the surgical exploration. The pathological examination of the surgical piece disclosed a calcified hydatic cyst and a focal nodular hyperplasia. The patient remains asymptomatic seven months after surgery.

Therapeutic effects of Sophora moorcroftiana alkaloids in combination with albendazole in mice experimentally infected with protoscolices of Echinococcus granulosus

The objective of the present study was to determine if the combination of alkaloids from Sophora moorcroftiana seeds and albendazole might be effective in the treatment of experimental echinococcosisin female NIH mice (6 weeks old and weighing 18-20 g, N = 8 in each group) infected withprotoscolices of Echinococcus granulosus. Viable protoscolices (N = 6 x 103) were cultured in vitro in 1640 medium and mortality was calculated daily. To determine the in vivo efficacy, mice were inoculated intraperitoneally with viable protoscolices and then treated once daily by gavage for three months with the alkaloids (50 mg kg-1 day-1) and albendazole (50 mg kg-1 day-1), separately and in combination (both alkaloids at 25 mg kg-1 day-1 and albendazole at 25 mg kg-1 day-1). Next, the hydatid cysts collected from the peritoneal cavity of the animals were weighed and serum IL-4, IL-2, and IgE levels were analyzed. Administration of alkaloids to cultured protoscolices showed significant dose- and time-dependent killing effects. The weight of hydatid cysts was significantly decreased upon treatment with each drug (P < 0.01), but the decrease was more prominent and the rate of hydatid cyst growth inhibition was much higher (76.1 percent) in the group receiving the combined treatments (18.3 ± 4.6 mg). IL-4 and total IgE were decreased (939 ± 447 pg/mL and 2.03 ± 0.42 IU/mL, respectively) in serum from mice treated with alkaloids and albendazole compared with the untreated control (1481 ± 619 pg/mL and 3.31 ± 0.37 IU/mL; P < 0.01). These results indicate that S. moorcroftiana alkaloids have protoscolicidal effects and the combination of alkaloids and albendazole has significant additive effects.

Hydatid disease of the first rib causing thoracic outlet syndrome

To present a case of hydatid disease of the first rib as a rare cause of thoracic outlet syndrome. A 57-year-old female patient who had suffered from pain on the left shoulder radiating to the arm and numbness and weakness on the left arm for 3 months was admitted to our hospital. She had undergone an operation due to a mass lesion of the first rib compressing the thoracic outlet which was detected in the preoperative examinations. During the intraoperative examination it was decided that the lesion was a hydatid cyst and the first rib was totally resected. This report shows that hydatid disease should be taken into consideration amongst the tumoral diseases of the first rib as a very rare cause of thoracic outlet syndrome
