The computed tomography (CT) findings of 3 patients with Ewing's sarcoma and 10 patients with a variety of benign rib lesions including osteomyelitis, hemangiomatosis, eosinophilic granuloma, aneurysmal bone cyst, neurofibromatosis, enchondroma, and Jarcho-Levin syndrome are presented. CT is of great value in demonstrating characteristic findings of several benign rib lesions. Also, CT accurately shows the destructive pattern of the rib lesion, the presence of pleural effusion, and the local spread of the soft tissue mass. When an aggressive rib lesion with pleural effusion is encountered in an infant or child, Ewing's sarcoma must be excluded unless this lesion has characteristic radiographic findings and a strong clinical history that suggest another diagnosis. The CT findings and differential diagnosis of rib lesions are discussed. Three-dimensional CT well demonstrated the appearance of congenital rib anomalies.
本文介绍了3例尤因肉瘤患者以及10例患有多种良性肋骨病变（包括骨髓炎、血管瘤病、嗜酸性肉芽肿、动脉瘤样骨囊肿、神经纤维瘤病、内生软骨瘤和贾科-莱文综合征）患者的计算机断层扫描（CT）结果。CT在显示几种良性肋骨病变的特征性表现方面具有重要价值。此外，CT能准确显示肋骨病变的破坏模式、胸腔积液的存在以及软组织肿块的局部扩散情况。当在婴幼儿或儿童中遇到伴有胸腔积液的侵袭性肋骨病变时，除非该病变具有特征性的影像学表现以及强烈提示其他诊断的临床病史，否则必须排除尤因肉瘤。本文讨论了肋骨病变的CT表现及鉴别诊断。三维CT很好地显示了先天性肋骨异常的外观。
