In January 2018, a young male of Didelphis aurita (Wied-Neuwied, 1826), the Brazilian common opossum, was admitted for veterinary evaluation at the Recovery Clinic of Wild Animals of Estácio de Sá University, CRAS, in Rio de Janeiro, Brazil, due to the presence of a partially duplicated right hind limb. After x-ray evaluation, polymelia associated with syndactyly was diagnosed. The images revealed the following alterations on the right limb: single femur with increased diameter, two tibiae, two fibulae and absence of hallux. The observed malformations were restricted to the hind right limb, which remains functional. This is the first report of such anomalies in an individual of Didelphis aurita.
2018年1月，一只巴西普通负鼠（Didelphis aurita，维德-诺伊维德，1826年）幼崽因右后肢部分重复而被送往巴西里约热内卢埃斯塔西奥·德·萨大学野生动物康复诊所（CRAS）进行兽医评估。经X光评估后，诊断为多指（趾）畸形合并并指（趾）畸形。图像显示右肢有以下改变：单根股骨，直径增大，两根胫骨，两根腓骨，且无拇趾。观察到的畸形仅限于右后肢，该肢体仍有功能。这是首例关于巴西普通负鼠个体出现此类异常的报告。
