A three-year-old Saanen goat showed limb ataxia and was necropsied because of the poor prognosis. Histopathologically, foreign body granulomas were observed in the left brachial plexus and cervical spinal cord. Central chromatolysis in the neurons of the descending motor tract was observed. The Setaria digitata (S. digitata) gene was identified by molecular biological examination using the paraffin blocks of the left brachial plexus. These results suggested that S. digitata had reached the left brachial plexus and cervical spinal cord via the bloodstream, and that neuropathy in the descending motor tract might be directly responsible for the limb ataxia.
An 11-year-old intact, male Maltese dog was referred to the Osaka Prefecture University Veterinary Teaching Hospital due to a large cyst in the abdominal cavity and left adrenomegaly. A physical examination revealed marked abdominal distention and respiratory effort on day 1. An abdominal ultrasound revealed the soft tissue structure to be a cyst-like mass, which appeared to be connected to the enlarged left adrenal gland. On day 7, a computed tomography (CT) scan was performed to plan the surgical removal of the left adrenal gland and cyst-like mass. The CT scan revealed a large cyst in the left mid-abdominal cavity extruding from the enlarged left adrenal gland (2.0×2.5 cm) and atrophy of the right adrenal gland (0.2×0.3 cm). Based on histopathological and immunohistochemical findings, the cyst was diagnosed as a neuroblastoma arising in the adrenal medulla, and the enlarged left adrenal gland was diagnosed as an adrenocortical adenocarcinoma. Neuroblastoma arising in the adrenal medulla of dogs has rarely been reported, and this case was considered extremely rare with a concurrent diagnosis of adrenocortical adenocarcinoma.
In the Hokkaido venison inspection project, veterinary inspectors examined 368 deer and found that 8 had
pulmonary abnormalities. The affected deer were captured and fed until they were slaughtered. In 7 of the 8
cases, the lesions were single or multiple firm nodules located in the lung parenchyma, and were histologically
characterized by a combination of caseous granuloma or caseous necrosis and intralesional Aspergillus-like
fungi. In 3 of the 7 cases, the fungi were identified as Aspergillus fumigatus using molecular biological
methods. Accordingly, the 7 deer were diagnosed with pulmonary aspergillosis. Based on its frequency
among the detected pulmonary lesions and the severity of the advanced cases, it was concluded that
aspergillosis is a significant lung disease in deer. Pulmonary aspergillosis lesions can be readily palpated
during manual inspections, and appropriate visceral examinations including palpation are necessary to
determine the health status of deer for venison.
