Abstract：
UNASSIGNED: Supernumerary ribs are very rare. They may occur at any level of the spine. We present here a case of an unusual localization of an extra rib that has not been previously described in the literature.
METHODS: A 4-year-old girl, with no medical history, presented with a congenital deformity in the sternal region mimicking a tail. The tail-like structure had a bony axis and was covered by normal skin and hairs. A computed tomography of the chest demonstrated that this structure was an abnormal bone articulated with the the sternum. For cosmetic purposes, we have decided to resect the malformation. On histopathological examination, it was a supernumerary rib.
UNASSIGNED: A review of the literature reveals a global incidence of cervical ribs ranging from 0.04 % up to 4.5 %, intrathoracic ribs in about 50 cases to date and very few reports on supernumerary ribs in the lumbar and sacral region. We were unable to find any similar cases of supernumerary ribs in the sternum.
CONCLUSIONS: Supernumerary ribs are rare and benign congenital anomalies. This case report describes an unusual localization of an extra rib in the sternum mimicking a tail.

摘要：
■多余的肋骨非常罕见。它们可能发生在脊柱的任何水平。我们在这里介绍了一个异常定位的额外肋骨的案例，该案例以前在文献中没有描述过。
方法：一个4岁的女孩，没有病史,在模仿尾巴的胸骨区域表现出先天性畸形。尾巴状结构具有骨轴，并被正常的皮肤和毛发覆盖。胸部计算机断层扫描显示该结构是与胸骨铰接的异常骨。为了美容目的，我们决定切除畸形。在组织病理学检查中，这是一个多余的肋骨。
■对文献的回顾显示，颈肋骨的全球发病率从0.04%到4.5%不等，迄今为止，胸内肋骨约50例，腰椎和骶骨区多余肋骨的报道很少。我们在胸骨中找不到任何类似的多余肋骨病例。
结论：多余肋骨是罕见的良性先天性畸形。此病例报告描述了胸骨中模仿尾巴的多余肋骨的异常定位。
