A 16-yr-old female blue and gold macaw (Ara ararauna) was presented with an acute history of lethargy, inappetance, ataxia, and paralysis. The bird had rapidly progressed from a normal state to complete inability to perch or ambulate within a 48-hr period. Neurologic examination revealed bilateral hind limb paresis with upper motor neuron signs present in both legs and the vent. Radiographs identified multiple nodular soft-tissue opacities within the cranial coelomic cavity and a single nodule superimposed with the thoracic spine. The bird was euthanized and submitted for necropsy, which revealed a primary pulmonary adenocarcinoma with multiple sites of osseous metastasis, including the vertebrae, and subsequent spinal cord compression. This is the first report of pulmonary adenocarcinoma in this species, although reports of similar tumors in other psittacines have been published. This report, along with others previously published, suggests that vertebral metastasis of primary pulmonary tumors may be more common in psittacine species than previously recognized and, as such, should be considered as a differential diagnosis in psittacine birds exhibiting signs of neurologic dysfunction attributed to a spinal cord lesion.

A 22-year-old female African black-footed penguin (Spheniscus demersus), housed indoors with other African and rockhopper penguins, was presented acutely with lethargy, ataxia, and hind limb weakness after a molt. The penguin would assume a hunched position and, when resting, sat on its hocks or lay on its keel. Physical and neurologic examination revealed hind limb paraparesis, proprioceptive deficits, and tiptoe walking. Results of a complete blood cell count and biochemical analysis revealed mild heterophilic leukocytosis, anemia, mild hypoalbuminemia, hypokalemia, and hyperuricemia. Results of whole-body radiographs and coelioscopy were unremarkable. Two computed tomographies of the spine at a 3-month interval revealed a lesion at the mobile thoracic vertebra proximal to the synsacrum with associated spinal cord compression. The penguin was treated with itraconazole, doxycycline, and meloxicam, and it initially improved with return to near normal gait and behavior. However, 5 months after the onset of clinical signs, the penguin was euthanatized after a relapse with worsening of the neurologic signs. Postmortem and histopathologic examination revealed focal granulomatous discospondylitis at the penultimate mobile thoracic vertebra, with intralesional bacteria from which Staphylococcus aureus was cultured.

Five adult tigers (Panthera tigris) presented with a range of clinical signs, including paresis (2/5), lameness (2/5), ataxia (3/5), anorexia (5/5), and lethargy (5/5). Each tiger demonstrated elevated plasma globulin levels (7.8-14.8 g/dl; [reference interval 2-5.1 g/dl]) on routine biochemistry, confirmed as a monoclonal gammopathy using protein electrophoresis. Serum gammaglobulin concentration ranged from 5 to 7.5 g/dl, or 45.1-63.4% of total protein concentration. Azotemia was present in three tigers. Diagnostics and management varied with the presenting signs but included magnetic resonance imaging, radiography, chemotherapy, supportive care, and euthanasia. In each case, necropsy revealed a neoplastic plasma cell proliferation in the bone marrow and one or more extramedullary sites. Lytic lesions in the thoraco-lumbar spine were found in three animals, and one lesion was associated with spinal cord compression. Splenomegaly was present in 4/5 cases. Histopathology confirmed a plasma cell neoplasm in each case, and immunohistochemistry staining with multiple myeloma oncogene 1 (MUM1) was positive in each case. CD20 staining was performed in two cases and was positive in one. CD3 staining was performed in the same two cases, and was negative in each. Based on the clinical, gross, microscopic, and immunohistochemical findings, myeloma was diagnosed in all five tigers.
