Abstract
- A 20-year-old male Moluccan eclectus ( Eclectus roratus ) was presented with a history of falling off the perch, ataxia, unilateral blindness, hyporexia, and progressive lethargy. The eclectus was found to have a leukocytosis (52 × 10 <superscript>3</superscript> cells/µL), characterized by an absolute and relative heterophilia (42.6 × 10 <superscript>3</superscript> cells/µL and 82%, respectively), relative lymphopenia (18%), elevated bile acids (88 µmol/L), and elevated triglycerides (236 mg/dL). Radiographic images revealed a mass effect within the caudal coelom. After 13 days of outpatient supportive care, the patient was rechecked and had normalized bile acids (<35 µmol/L), static triglycerides (232 mg/ dL), and hyperuricemia (18.6 mg/dL). Computed tomography was performed antemortem with and without iodinated contrast agent, 4 mL/kg IV over 2 minutes, and a mass was found associated with the left kidney. Due to worsening neurologic signs and involvement with surrounding structures, the owner elected euthanasia. Before the postmortem examination, a postmortem intravascular contrast agent was used to provide a more thorough visualization of internal anatomical structures, including left renal vasculature disruption, mass vasculature, caudal coelomic organ displacement, and increased irregular optic chiasm radiodensity. Postmortem, a 4 × 4.1 × 5.1-cm white to tan mass was identified. Histopathology confirmed a seminoma with metastasis to the kidneys and optic chiasm. Seminomas have been described in avian species; however, seminoma metastasis in an eclectus parrot confirmed by histopathology has not been reported, and optic chiasm metastasis of a seminoma has not been described in any avian species. This report describes postmortem computed tomographic angiography of metastatic seminoma in a Moluccan eclectus with metastasis to the optic chiasm.
