A 9-year-old male timneh African grey parrot (Psittacus erithacus timneh) was presented because of inability to fly and suspected trauma. The owner also had observed dyspnea, with tail bobbing and open-beak breathing. On clinical examination, a hard, painful mass was palpable in the left proximal humerus and axillary area. Radiographs revealed a radiodense soft tissue mass of the left humerus with no bony involvement, multifocal opacities in lung and air sacs, and an enlarged spleen. An asymmetric, vascularized cyst was detected in the mass by ultrasound examination. Results of biopsy of the mass revealed multifocal cysts composed of unilayer isoprismatic cells laying in vascularized connective tissue. Because of the severity of clinical signs and the poor clinical condition, the bird was euthanatized. On postmortem examination, the findings were air sac cystadenocarcinoma involving the humeral air sac with metastases in the spleen and kidneys, atherosclerosis, pneumoconiosis, and mycotic granulomatous pneumonia and airsacculitis with isolation of Aspergillus niger.
一只9岁的雄性提姆neh非洲灰鹦鹉（Psittacus erithacus timneh）因无法飞行和疑似外伤前来就诊。主人还观察到其呼吸困难，伴有尾巴摆动和张嘴呼吸。临床检查时，在左肱骨近端和腋窝区域可触及一个坚硬、疼痛的肿块。X线片显示左肱骨有一个高密度软组织肿块，无骨质受累，肺和气囊有多处不透明区，脾脏肿大。超声检查在肿块中检测到一个不对称的、血管化的囊肿。肿块活检结果显示，多灶性囊肿由单层等棱柱形细胞组成，位于血管化的结缔组织中。由于临床症状严重且病情不佳，这只鸟被实施了安乐死。尸检发现，气囊囊腺癌累及肱骨气囊，脾脏和肾脏有转移灶，还有动脉粥样硬化、尘肺、霉菌性肉芽肿性肺炎和气囊炎，分离出黑曲霉。
