Abstract：
This report describes the diagnosis and treatment of a benign renal cyst in an adult, female golden eagle (Aquila chrysaetos) presented for unilateral leg lameness. A cyst at the cranial division of the left kidney was diagnosed by computed tomography and was suspected of compressing the lumbosacral nerve plexus, resulting in limb lameness. The renal cyst was incompletely excised because the cyst wall was closely adhered to the kidney parenchyma and local blood supply. Fluid analysis and surgical biopsy of the cyst and left kidney confirmed the diagnosis of a benign renal cyst. No evidence of an infectious, inflammatory, or neoplastic etiology was noted. Postoperatively, the eagle\'s lameness resolved and the bird was ultimately released following recovery. During treatment for the renal cyst, the eagle was concurrently found to have increased serum titers on elementary body agglutination for Chlamydia psittaci and a positive titer for Aspergillus species antibody testing. The bird was administered doxycycline, azithromycin, and voriconazole for treatment of these potential pathogens prior to release. Unfortunately, the eagle was found dead 86 days postrelease due to an unknown cause. To the authors\' knowledge, this is the first report of a golden eagle with a benign solitary renal cyst causing unilateral lameness secondary to nerve compression that was resolved with surgical excision.
摘要：
本报告描述了成人良性肾囊肿的诊断和治疗，雌性金鹰（Aquilachrysaetos）表现为单腿跛行。计算机断层扫描诊断为左肾颅部囊肿，怀疑压迫腰骶神经丛，导致四肢跛行。肾囊肿未完全切除，因为囊肿壁紧密粘附于肾实质和局部血液供应。囊肿和左肾的液体分析和手术活检证实了良性肾囊肿的诊断。没有传染病的证据,炎症，或注意到肿瘤的病因。术后,鹰的跛行解决了，这只鸟最终在恢复后被释放。在治疗肾囊肿期间，同时发现老鹰的衣原体凝集素的血清滴度增加，曲霉属抗体检测的滴度呈阳性。这只鸟服用了强力霉素，阿奇霉素,和伏立康唑用于在释放之前治疗这些潜在的病原体。不幸的是,老鹰因不明原因被发现死于释放后86天。就作者所知，这是首例金鹰伴良性孤立性肾囊肿，引起神经压迫继发的单侧跛行，经手术切除解决。
