A 25-year-old female macaroni penguin (Eudyptes chrysolophus) was diagnosed with exophthalmos secondary to retrobulbar neoplasia through use of computed tomography (CT). Histopathologic examination of the mass supported a diagnosis of malignant round cell neoplasia. Immunohistochemical (IHC) labeling was applied to determine cell origin; the neoplastic cells did not label with T-cell marker CD3 or B-cell marker BLA.36 and could not be further characterized. The scleral ossicles precluded evaluation of the retrobulbar space by ultrasonography; therefore, CT scanning is recommended for examination of intraorbital structures in penguin and other avian species.
一只25岁的雌性通心粉企鹅（冠企鹅）通过计算机断层扫描（CT）被诊断为继发于球后肿瘤的眼球突出。对肿块进行组织病理学检查支持恶性圆形细胞瘤的诊断。应用免疫组织化学（IHC）标记来确定细胞来源；肿瘤细胞未用T细胞标志物CD3或B细胞标志物BLA.36标记，无法进一步明确特征。巩膜小骨妨碍了通过超声检查球后间隙；因此，建议使用CT扫描来检查企鹅和其他鸟类的眶内结构。
