          ABSTRACT: Dioctophyme renale is a parasite of the nematode class that can infect various species, including humans and dogs. Usually, the parasite migrates to the right kidney of the definitive host. Although, aberrant migrations have been previously reported, they mainly occur without clinical manifestations. No reports of dyspnea secondary to D. renale infestation has been found in the reported literature. The aim of this paper is to report intense respiratory distress caused by the presence of the parasite in the thoracic cavity of a dog. Radiographic images revealed multiple circular structures with a cavity with a radiopaque, thick contour in the thorax, which raised the suspicion of pulmonary bullae. Ultrasound examination revealed nematode infestation in the right kidney, scrotum, and thoracic cavity. Subsequently, right nephrectomy, orchiectomy and trans-sternal thoracotomy were performed to remove the parasites. The patient exhibited recovery after the procedures.

          RESUMO: Dioctophyme renale é um parasita da classe de nematoda que pode infectar diferentes espécies, incluindo humanos e cães. Normalmente, o parasita migra para o rim direito do hospedeiro definitivo. Embora migrações erráticas tenham sido relatadas anteriormente, estas geralmente ocorrem sem manifestações clínicas. Não foram encontrados relatos de dispnéia secundária à infestação de D. renale. O objetivo deste trabalho é relatar a presença do parasita na cavidade torácica de um cão, causando angústia respiratória. As imagens radiográficas revelaram a presença de múltiplas estruturas circulares com aspecto de cavidade e contorno espesso radiopaco no tórax, o que suscitou a suspeita de bullae pulmonar. O exame de ultra-som foi determinante na revelação de infestação múltipla por nematódeos, no rim direito, escroto e cavidade torácica. Posteriormente, como medida terapêutica, foram realizadas os procedimentos de nefrectomia direita, orquiectomia e toracotomia transesternal para remoçãodos parasitas. O paciente evoluiu clinicamente bem após os procedimentos.

          Dioctophyme renale (Goeze, 1782) in the abdominal cavity of a domestic cat from Brazil.

          This study reports a case of parasitism by the giant kidney worm, Dioctophyme renale (Goeze, 1782), in the abdominal cavity of a domestic cat from Brazil. A female adult cat presenting prostration, dehydration, physical debility, pronounced jaundice and ascitis, was taken to the Department of Animal Parasitology of the Veterinary Institute of the Universidade Federal Rural do Rio de Janeiro, Brazil. Clinical signs suggested a case of peritonitis. The cat's clinical condition was grave and death occurred within a few days. During necropsy, a brownish-red nematode, 24.9cm long, was found in the abdominal cavity and was identified as a male adult D. renale. This study reports the first confirmed case of dioctophymatosis in the domestic cat. The parasite's aberrant location in the abdominal cavity suggests that the domestic cat is not a suitable host.

            Thoracoscopic-assisted lung lobectomy in the dog: report of two cases.

            The benefits and application of thoracoscopy with selective ventilation, as an adjunct to thoracotomy, in facilitating pleural exploration and lung lobectomy in two dogs are presented. Similar thoracoscopic-assisted procedures are commonly used in human patients because there is better exposure and they are technically less demanding than thoracoscopy alone, while causing less postoperative morbidity than conventional thoracotomy. There are no previous reports of thoracoscopic-assisted surgery in the veterinary literature. In the cases described, thoracoscopic-assisted mini-thoracotomy was an effective, minimally-invasive approach for ipsilateral hemithorax exploration and lung lobectomy.

              Dioctophymatosis renalis in humans: first case report from India.

              Dioctophymatosis is an infestation by Dioctophyma renalis (the giant kidney worm), a relatively uncommon parasitic roundworm that infects carnivorous mammals. Since the early 1900s, dioctophymatosis has been confirmed in < 20 humans worldwide. A 70-year-old man attended our Hospital, complaining of having expelled 2 large worms while urination along with haematuria 2 days post-admission. On MR UROGRAM we confirmed it as dioctophyma renale.wet mount preparation of urine under microscopy showed eggs specific for the parasite. On review of literature we found that this was the first case reported in india.
