imaging diagnosis the computed tomographic appearance of a giant cell tumor affecting the mandible in a Pygmy Goat
Veterinary Radiology & Ultrasound, 2016Co-Authors: Jonathon J Dixon, R R Pool, R Weller, Sonja Jeckel, Alex McsloyAbstract:A 3-year-old male neutered Pygmy Goat presented for evaluation of a progressive mandibular swelling and inappetence. A computed tomographic (CT) scan of the head and thorax was performed under general anesthesia. Computed tomography revealed an extensive multiloculated, markedly expansile lesion within the right hemimandible, which involved the articular surface of the temporomandibular joint. The Goat was euthanased due to a poor prognosis and postmortem examination confirmed the diagnostic imaging findings. Histopathology was strongly suggestive of a multinucleated giant cell tumor, therefore this condition should be considered as a differential diagnosis in Goats presenting with expansile mandibular mass lesions.

Costal Mesenchymal Chondrosarcoma with Diffuse Pleural and Pericardial Explantation in a Pygmy Goat
2016Co-Authors: Eric D Lombardini, Andres De La Concha, Virginia Pierce, R R PoolAbstract:Abstract: A 3 year old intact male Pygmy Goat developed progressive weakness and eventual recumbancy over the course of 1 week, while maintaining its ability to eat and drink. The animal died and at necropsy, the parietal pleural surfaces and the pericardial surface were noted to be covered with firm, white, variably sized nodules that often formed linear arrays or coalesced into larger clumped aggregates. The visceral pleural surfaces of the ventral lung lobes were also covered with similar nodules. Histopathological and im-munohistochemical evaluation of the submitted tissues revealed a diagnosis of mesenchymal chondrosarcoma with extensive seeding throughout the thoracic cavity. (DOI: 10.1293/tox.2013-0040; J Toxicol Pathol 2014; 27: 81–85) Key words: chondrosarcoma, explantation, Goat, mesenchymal, pleural Chondrosarcomas are malignant tumors of mesen-chymal origin arising either within bone, and described as either central or medullary, or within the periosteum and termed as peripheral1–3. These tumors are relatively well described in the veterinary literature, having been diag-nosed in most domestic species to include a variety of dog breeds2,4–8, cats1, ferrets9, sheep10, horses11, cows9,12,13 as well as single reports in the mandible of a camel14 and the hu

congenital cystic disease of the liver and kidney in a Pygmy Goat
Journal of Veterinary Diagnostic Investigation, 2000Co-Authors: Shelley J Newman, Teri Leichner, Mark Crisman, Jose RamosAbstract:A 1-month-old Pygmy Goat was presented with abdominal distension and hematuria. Anemia, leukocytosis, and increased bilirubin and blood urea nitrogen levels suggested renal and hepatic disease. Radiographs revealed bilateral renomegaly, and ultrasound confirmed bilateral hydronephrosis. Necropsy findings determined that the renomegaly was due in part to edema and marked cystic tubular distension. Similarly, intrahepatic bile ducts were ectatic. The character and distribution of the gross and histologic lesions were consistent with a polycystic disorder, presumably congenital, affecting the liver and the kidney.
