“…Ultrasound also confirmed the presence of a progressive duct ectasia, with an increase in size and tortuousness of bile ducts, and with moving echogenic forms in the dilated bile ducts being detected from 9 to 10 weeks postinfection. These data coincide with previous studies confirming that sonography may be specially useful in the biliary stage of fascioliasis for demonstrating moving flukes (Bassily et al 1989;Han et al 1999).…”

Radiological features and biochemical changes were investigated during the parenchymal and ductal phases of chronic Fasciola hepatica infection in sheep. The activities of plasma aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and gamma-glutamyl transpeptidase (GGT), plasma levels of IgG anti- F. hepatica and serial ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) findings were studied in eight sheep infected with 150 F. hepatica metacercariae. Experimental fluke infection provoked an increase in plasma level of IgG directed against F. hepatica and in plasma LDH and AST activities from 4 weeks after infection. Enzyme activities did not significantly differ from the baseline after 15 and 12 weeks for LDH and AST, respectively. GGT activity increased from 9 weeks postinfection and still remained significantly elevated at 18 weeks. In the parenchymal phase, both CT and MRI showed nodular lesions in five animals and MRI could also detect early tracks in the subcapsular area in three sheep. Ultrasound findings were nonspecific in this phase. Ductal dilatation was shown by ultrasound, CT and MRI in almost all animals, although MRI was inferior to CT in depicting a mild ductal dilatation. Moving echogenic forms in the dilated bile ducts were observed by ultrasound from 9 weeks postinfection in seven of the eight sheep. Moving worms were only demonstrated in four sheep at CT and in a single sheep at MRI. This study shows that radiological findings may be useful in studies of fluke-induced liver damage.

Fasciola hepatica, a leaf shaped trematode that is common in cattle, sheep and goats, is acquired by eating raw water plants like watercress or drinking water infected with the encysted form of the parasite. The varied clinical presentations of fascioliasis still make a high index of suspicion mandatory. Besides having a wide spectrum of hepatobiliary symptoms like obstructive jaundice, cholangitis and liver cirrhosis, the parasitic infection also has extrabiliary manifestations. Until recently, extrahepatic fascioliasis has been reported in the subcutaneous tissue, brain, lungs, epididymis, inguinal lymph nodes, stomach and the cecum. In this report, a strange manifestation of the fasciola infection in a site other than the liver, a colonic fascioliasis, is presented.

“…En la fasciolasis hepática, su aspecto obliga a un alto grado de sospecha dado que puede ser indistinguible de otras lesiones focales hepáticas Ultrasonido: En fasciolasis hepática, se pueden ver lesiones focales hipoecogénicas, anfractuosas, bien definidas, de tamaño variable, con tendencia a coalescer (6) en un 96% de los casos (7,8) , aunque también se describen de ecogenicidad variable (9) . Sin embargo, no siempre es posible visualizar los trayectos que le dan el sello característico, por lo que su rol en fasciolasis aguda es menor.…”

“…Más específico es la observación de estructuras móviles en vesícula biliar y/o colédoco, representando la forma adulta de fasciola (6)(7)(8)(9) (Figura 5). Hay autores que sugieren que el US es de menor utilidad que la TC para el diagnóstico (10) , sin embargo, nosotros consideramos que su rol en fasciolasis hepática es indudable, ya que permite una evaluación más precisa de la vesícula y vía biliar extrahepática.…”

Human fasciolasis is a zoonosis linked to the trematod Fasciola hepatica, which affects primarily bovine and ovine cattle, and by chance, humans. Difficulty in clinical diagnosis due to its various patterns of presentation, it may be necessary to obtain images that enable a diagnosis. Therefore, in endemic zones (such as Latin America, Asia, and northern Africa), should include this entity as differential diagnosis for focal liver lesion, especially in the presence of eosinophilia. Key words: Fasciolasis, Focal liver lesion.Resumen: La fasciolasis humana es una zoonosis causada por la Fasciola hepática, trematodo que en su vida adulta afecta principalmente el ganado ovino y bovino, siendo el hombre huésped accidental. La dificultad en el diagnóstico clínico, dada su variada sintomatología, muchas veces requerirá del apoyo imagenológico, por lo que el radiólogo debe estar preparado y conocer la epidemiología de este patógeno, especialmente en aquellas zonas endémicas (Latinoamérica, zonas de Asia y el Norte de África). Es importante considerarla dentro del diagnóstico diferencial de lesiones focales hepáticas, especialmente en el contexto clínico de eosinofilia.
