“…Além do rim direito, como é mais comumente relatado devido à sua proximidade com o duodeno [15,24], também pode ser encontrado livre na cavidade abdominal [29], no tecido subcutâneo [10], no testículo [31], em ureter e bexiga [15,29] e até na medula espinhal, causando paraparesia [2].…”

Background: Dioctophimosis is a parasitic disease caused by Dioctophyma renale, more commonly known as "giant Kidney worm," and can be found in other organs or free in the abdominal cavity, which is related to the patient's eating habits. Most of the animals affected are asymptomatic. The diagnosis is made through ultrasonography, finding eggs of the parasite in the urine, or necropsy. The treatment of choice is nephrectomy of the affected kidney. We aimed to report the accidental diagnosis of parasitism by D. renale in an 8-year-old dog, which was surgically treated by nephrectomy of the right kidney after evident destruction of the renal parenchyma on ultrasonography.Case: An 8-year-old Boxer female dog underwent a physical examination and showed a mass in the region of the left caudal thoracic breast, bilateral alopecia on flanks, and purulent ocular secretions. Laboratory tests of complete blood count (CBC) and serum biochemical profile, X-ray examination, and ultrasonography were requested. Anemia was observed on the erythrogram, and enzymes (creatinine, urea, alanine aminotransferase [ALT], and albumin) were within normal limits. There were no abnormalities on X-ray examination, and abdominal ultrasonography showed slight splenomegaly, enlarged left kidney, reduced corticomedullary region, measuring approximately 7.63 cm longitudinally. In the right kidney, loss of the renal parenchyma, measuring approximately 5.49 cm in diameter and the presence of a cylindrical and rounded structure, typical of D. renale infection. After this, a urinalysis was suggested, which revealed the presence of the helminthic eggs, confirming the diagnosis. The owner was informed about the need for nephrectomy of the affected kidney as treatment. The kidney showed destruction of the renal parenchyma. A single parasite was removed, measuring approximately 46 cm in length. The patient was successfully treated and was hospitalized for 4 days for observation and evaluation of function of the contralateral kidney.Discussion: The parasitic infection of the animal was due to the ingestion of fish contaminated by the aquatic anelid Lumbriculus variegatus, and the reported patient had access to home-cooked food and ingested water near the farm. D. renale is the largest nematode capable of parasitizing the kidney, reaching up to 100 cm in length, and was 46 cm long in the present case. Usually, when there is unilateral involvement, the vast majority of parasitized animals do not present clinical signs or show nonspecific signs such as hematuria and apathy, or as observed in the present case, the patient is asymptomatic. The diagnosis often occurs through ultrasonography and urine tests, which are considered essential to diagnose the parasite, but the diagnosis is often made on necropsy. Due to its proximity to the duodenum, the parasite is usually found in the right kidney, and it may be found in other organs as well. In the present case, the parasite was found in the right kidney of the patient. Usually, hypertrophy of the contralateral kidney (7.86 cm in this case) is observed on ultrasonography, which is a compensatory mechanism for the lack of normal function of the affected kidney of the affected kidney. The case occurred in the state of Mato Grosso, where there are no records of parasitism by D. renale in domestic dogs, compared with other states. Since the parasite usually affects the kidney, the treatment of choice is nephrectomy, especially if the other kidney can compensate for the absence of the other kidney, a technique that proved to be effective with excellent prognosis in the patient described.

“…O D. renale tem predileção pelos rins, principalmente o rim direito, provavelmente devido à sua proximidade com o duodeno (PEREIRA et al, 2006). Entretanto, o parasita pode ser encontrado no rim esquerdo, em outros órgãos, livre na cavidade abdominal, e até invadindo o espaço intra-dural (BACH et al, 2016).…”

RESUMOA dioctofimose, causada pelo nematódeo Dioctophyme renale, acomete frequentemente cães errantes e de hábitos alimentares pouco seletivos, podendo afetar também o homem. O parasita é grande, pode medir até cem centímetros de comprimento e se aloja geralmente no rim direito. O diagnóstico é obtido pela visualização dos ovos do D. renale durante o exame do sedimento urinário ou pelo achado do parasita à necropsia. O presente trabalho descreve um caso de parasitismo por este nematoide em cão atendido no Hospital Veterinário "Governador Laudo Natel" da Faculdade de Ciências Agrárias e Veterinárias, Jaboticabal, no qual a conduta terapêutica foi a realização de nefrectomia do rim acometido, devido à destruição do parênquima renal. A nefrectomia unilateral foi eficiente para a cura do paciente e eliminação do parasita. PALAVRAS-CHAVE:Canina; Nefrologia; Verminose; Zoonose. SUMMARYDioctophimosis, caused by the nematode Dioctophyme renale, frequently attacks erratic dogs and have poorly selective eating habits and, may also affects the man. The parasite is large, can be up to one meter long and usually is lodged to the right kidney. The diagnosis is obtained by the preview of D. renale eggs during the examination of the urinary sediment or by finding the parasite at necropsy. The present study describes a case of parasitism by this nematode in a dog attended at the "Governador Laudo Natel" Veterinary Hospital of the Faculdade de Ciências Agrárias e Veterinárias, Jaboticabal, in which the therapeutic management was the nephrectomy of the affected kidney, due to the destruction of the renal parenchyma. Unilateral nephrectomy was efficient for the cure of the patient and elimination of the parasite.

“…renale acomete o rim, principalmente o direito, penetra na cápsula renal e invade o parênquima, destruindo completamente o órgão. O parasita pode ser encontrado no peritônio, glândula mamária, bolsa escrotal, tecido subcutâneo, útero, ovário, cavidade torácica, pericárdio, linfonodo mesentérico e no espaço intra-dural (Kommers et al 1999, Pedrassani & Nascimento 2015, Bach et al 2016. Os parasitas adultos se reproduzem normalmente no rim direito e as fêmeas liberam os ovos através da urina (Pedrassani & Nascimento 2015).…”

RESUMO.-Este trabalho descreve dioctofimatose renal bilateral e disseminada em canino no município de Pelotas, na região sul do Rio Grande do Sul. Uma cadela sem raça definida, de dois anos de idade e semi-domiciliada foi submetida a exame ultrassonográfico observando-se alterações sugestivas de parasitismo por Dioctophyme renale. O animal veio à morte antes de ser conduzido para nefrectomia e remoção dos parasitas. Foi encaminhado para necropsia no Laboratório Regional de Diagnóstico da Faculdade de Veterinária da UFPel. Macroscopicamente, ao corte do rim direito observou-se atrofia do parênquima com formações císticas e exsudato serosanguinolento com quatro exemplares fême-as de D. renale. A cápsula renal media 0,4cm de espessura, e apresentava placas multifocais esbranquiçadas, irregulares e de consistência dura, medindo até 2cm de diâmetro. Na pelve do rim esquerdo, havia um parasita macho de 22cm. A bexiga possuía conteúdo escurecido e pastoso. Ainda, livre na cavidade abdominal, próximo ao rim direito havia outro parasita macho de 30cm. No fígado havia região cicatricial no lobo em contato com o parasita. No tórax identificou-se livre na cavidade e formando impressão sob a gordura pericárdica, um parasita macho de D. renale, medindo 20cm. Histologicamente, além de lesões características da enfermidade, observou-se metaplasia óssea na capsula renal direita. TERMOS DE INDEXAÇÃO:Dioctophyme renale, dioctofimatose, rim, metaplasia óssea, renal bilateral, canino.
