摘要

Objective To explore the incidence, pattern of distribution and imaging features of tumor and tumor-like disorders of the clavicle. Methods 56 cases with tumor and tumor-like disorders of the clavicle confirmed by pathology during 1963-01-2009-06 in our hospital were retrospectively studied. The incidence and imaging features were analysed. Results In 56 cases,there were 33 malignant and 15 benign lesions, 8 tumor- like disorders. The most common malignant tumors in order were metastatic tumors(20 cases), plasma cell myeloma( 5 cases), osteosarcoma(4 cases). The most common benign tumors was osteochondromas (4 cases). The most common tumor-like disorders was eosinophilic granuloma( 3 cases). Conclusion Tumors and tumor-like disorders of the clavicle are rare, most of which are malignant. The imaging appearances of benign and malignant clavicle lesions exist overlap. The incidence, pattern of distribution and imaging features of the clavicl diseases are helpful in diagnosis.%目的 探讨锁骨骨肿瘤和肿瘤样病变的病种分布及其影像学表现.方法 回顾性分析本院1963-01-2009-06期间经病理证实的锁骨病变56例,分析其发病情况及影像学表现.结果 锁骨病变共56例,其中良性骨肿瘤15例(26.8%),恶性骨肿瘤33例(58.9%),肿瘤样病变8例(14.3%).锁骨肿瘤种类较多,在恶性锁骨肿瘤中按发生比率依次为转移瘤20例(占35.7%)、浆细胞性骨髓瘤5例(8.9%)和骨肉瘤4例(占7.1%);良性骨肿瘤主要是骨软骨瘤4例(7.1%),肿瘤样病变依次为嗜酸性肉芽肿和骨囊肿,各3例(分别占5.4%),锁骨肿瘤占同期所统计的全身骨肿瘤的0.73%.结论 锁骨骨肿瘤和肿瘤样病变相对少见,且以恶性肿瘤为多,良性骨肿瘤和肿瘤样病变相对少见.锁骨病变的影像学表现大多缺乏特异性,部分良性病变可具有类似恶性肿瘤的影像征象.
