This paper describes a bilateral and disseminated renal dioctophymiasis in a canine in the municipality of Pelotas, southern region of Rio Grande do Sul, in Brazil. The two-year-old female dog with no defined race was semi-domiciled and was submitted to ultrasound examination presenting alterations suggestive of parasitism by Dioctophyme renale. The patient died before being led for nephrectomy and removal of the parasites. It was referred for necropsy at the Regional Diagnostic Laboratory of the UFPel Veterinary School. Macroscopically, at the cut of the right kidney, atrophy of the parenchyma with cystic formations and serosanguinous exudate with four female specimens of D. renale were observed. The renal capsule was 0.4cm thick and had irregular, hard, multifocal regions measuring up to 2cm in diameter. In the pelvis of the left kidney, there was a 22cm long male parasite. The bladder had darkened and pasty contents. Also, free in the abdominal cavity, near to the right kidney there was another male parasite of 30cm. In the liver there was a cicatricial region in the lobe in contact with the parasite. In the thorax, a male parasite of D. renale measuring 20cm, was identified free in the cavity and forming an impression under the pericardial fat. Histologically, in addition to the characteristic lesions of the disease, bone metaplasia was observed in the right renal capsule. |
