Abstract
Dioctophymosis is caused by Dioctophyme renale, a nematode that usually affects the right kidney of carnivores. The aim of this study was to report on a case of a dog with progressive weight loss and swollen abdomen that was diagnosed as presenting dioctophymosis. The patient underwent surgical treatment through which 34 nematodes were found, of which 18 were female and 16 were male, with a maximum length of 74 centimeters. The parasites were free in the abdominal cavity and inside the right kidney, and had caused peritonitis, free fluid, severe adherences between the abdominal organs and renal perforation. Parasitic diseases with a high number of specimens of this species are uncommon in dogs. The disease progresses with an inflammatory reaction and consequent formation of adherences and granulomatous tissue. This surrounds the eggs that were eliminated in the abdominal cavity by the free parasites. This disease occurs frequently in the city of Pelotas, Rio Grande do Sul, Brazil, where the patient of this report was living. To the best of authors' knowledge, this is the case with the largest number of specimens of D. renale removed from a single dog in vivo.
Highlights
A dioctofimose é causada por Dioctophyme renale, um nematódeo que geralmente afeta o rim direito de carnívoros
The right kidney is the organ mostly affected by this disease, which leads to destruction of the renal parenchyma, with consequent loss of organ function (Measures, 2001; Pedrassani & Nascimento, 2015)
Case reports describe the finding of the nematode free in the abdominal cavity (Paras et al, 2018; Butti et al, 2020), left kidney (Perera et al, 2017b), mammary gland (Paras et al, 2018), prostate (Butti et al, 2020) and abdominal musculature (Caye et al, 2018)
Summary
A dioctofimose é causada por Dioctophyme renale, um nematódeo que geralmente afeta o rim direito de carnívoros. The right kidney is the organ mostly affected by this disease, which leads to destruction of the renal parenchyma, with consequent loss of organ function (Measures, 2001; Pedrassani & Nascimento, 2015). Several specimens of free D. renale were removed from the abdominal cavity and from inside the right kidney, which presented perforation of its capsule, enabling translocation of the parasites.
