ABSTRACT
We report molecular identification of an adult Spirometra mansoni tapeworm retrieved from a crab-eating fox (Cerdocyon thous) in Colombia, confirming presence of this parasite in South America. This tapeworm is the causative agent of human sparganosis, commonly reported from Southeast Asia, and represents the second congeneric species with known zoonotic potential in the Americas.

Brain sparganosis is a non-common parasite infection by Diphyllobothrium or Spirometra mansonoides larvae. This last one is responsible for most of the infestations in humans. We report a 19 years male patient bearer of a brain sparganosis. The patient presented with headache and left hemiparesis. CT diagnosis of right thalamic lesions was made and aspiration biopsy was performed using stereotactic system, obtaining a whole and death larvae. Histopathology confirms a CNS parasitism and it was treated initially with albendazol. ELISA test confirmed Spirometra spp. infestation. The patient developed asymptomatic with total remission of the lesions. It constitutes the second report in Cuba of brain sparganosis.

Human sparganosis is a food borne zoonosis caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms of the genus Spirometra. Human infections are acquired by ingesting the raw or undercooked meat of snakes or frogs, drinking untreated water, or using raw flesh in traditional poultices. More than 1600 cases of sparganosis have been documented worldwide, mostly in east and southeast Asia. Sporadic cases have been reported in South America, Europe, and Africa, and several cases have been described in travellers returning from endemic regions. Epidemiological data suggest that the increased effect of sparganosis on human health is because of greater consumption of raw meat of freshwater frogs and snakes. This Review provides information about the Spirometra parasites and their lifecycles, summarises clinical features, diagnosis, and treatment of human sparganosis, and describes geographical distribution and infection characteristics of Spirometra parasites in host animals.

Se presenta el caso clínico de un varón con 19 años de edad y el diagnóstico de una esparganosis cerebral. Consultó por cefalea y una hemiparesia izquierda. En una tomografía computarizada cerebral con contraste se observaron lesiones talámicas derechas. Se realizó una biopsia cerebral guiada por estereotaxia con aspiración completa de un verme. En el estudio histopatológico se planteó un probable parasitismo de SNC y fue tratado inicialmente con albendazol. Se confirmó la infección por Spirometra spp. por test de ELISA. Evolucionó con regresión de síntomas y remisión imagenológica de las lesiones. Este caso constituye el segundo reporte en Cuba de una infestación cerebral por este parásito y aspiración estereotáctica de la larva de Spirometra spp.

We are reporting the case of an 8-year-old boy with history of seizures in whom the pathology exam of 2.5 by 3 cm surgical specimen obtained from a cortical-subcortical area of the de right occipital lobe showed a chronic granulomatous inflammatory process with a Spirometras pp larva. The patient was born and lived several years at a rural area of Tarija (Bolivia). This appears to represent the first reported case of this parasitic infection localized to the brain of a child in Argentina.

Se presenta el caso de un niño de 8 años con antecedentes de epilepsia en quien el examen anatomopatológico del material extraído de una lesión de 2,5 por 3 cm localizada en la zona corticosubcortical del lóbulo occipital derecho reveló la presencia de un proceso inflamatorio crónico granulomatoso con una larva de Spirometras pp. El paciente nació y vivió varios años en una zona rural de Tarija (Bolivia). Es el primer ejemplo pediátrico de esta infestación parasitaria a nivel cerebral reconocido en la Argentina.(AU)

Sparganosis in humans is an incidental infection and is known to be associated with eating insufficiently cooked meat of frogs and snakes or drinking unboiled stream water. Although it can involve various internal organs, pulmonary and pleural involvement due to sparganum is rare. Because we recently experienced two cases involving lung parenchyma and pleura that were misdiagnosed as bacterial pneumonia and lung cancer, we herein intend to present them in detail.
