Hallazgo de Dioctophyme renale en la cavidad torácica de un canino

Abstract

The adult stage of Dioctophyme renale usually parasites the right kidney of dogs and other wild and domestic mammals, although it may affect other organs or tissues as well. The purpose of this study was to report the finding of adults and eggs of D. renale in body cavities of a female dog, 18 months-old. The animal was found dead by the owner, who later asked for a necropsy at the School of Veterinary Science, Universidad Nacional del Nordeste, Corrientes, Argentina, as a poisoning was suspected as cause of death. Necropsy revealed the presence of two adult worms, one in the abdominal cavity and the other in the thorax, the latter measuring 40 cm long and 10 mm in diameter. In the mediastinal pleura it was verified the presence of 12 perforations, 20 to 50 mm in diameter. The lungs showed focal lesions, being more numerous in the right middle lobe. Histological sections revealed numerous eggs of D. renale. Histopathological findings characterized the existence of a multifocal granulomatous pleuritis.
