摘要
目的研究原发于髂骨的恶性骨肿瘤及其影像学表现、鉴别诊断要点。方法回顾性分析20例经病理证实的髂骨原发恶性肿瘤的影像学表现,分别观察髂骨破坏方式、病灶结构、骨外软组织肿块范围与骨皮质破坏范围的关系。结果 20例髂骨原发恶性肿瘤中恶性淋巴瘤9例,浆细胞瘤2例,多发性骨髓瘤2例,尤文氏肉瘤2例,小细胞恶性肿瘤1例,骨肉瘤2例,软骨肉瘤1例,骨神经内分泌瘤1例。18例患者影像学表现为虫噬状或溶骨性骨质破坏,各有1例多发性骨髓瘤X线平片及浆细胞瘤CT扫描未显示明显骨质破坏。16例伴骨旁巨大软组织肿块。骨外软组织肿块范围大于骨皮质破坏范围13例,2例骨肉瘤,1例软骨肉瘤,破坏范围相当。结论髂骨原发恶性肿瘤中骨髓源性肿瘤明显多于骨基本组织来源的肿瘤,以恶性淋巴瘤最为多见。比较骨外软组织肿块范围与骨皮质破坏范围有利于两者鉴别。
Objective To investigate the imaging features and the differential diagnosis value of primary malignant tumor of ilium. Methods The imaging features of 20 cases with primary malignant tumor of ilium, proved by pathology, were retrospectively analyzed. The mode of bone desturction in ilium, structure of lesion, and the relation between the size of soft masses and the degree of bone desturction were observed. Results 20 cases of primary malignant tumor of ilium included malignant lymphoma （n=9）, plasmacytoma （n=2）, multiplemyeloma （n=2）, Ewing抯 sarcoma （n=2）, primary cellule tumor （n=1）, osteosarcoma （n=2）, chondrosarcoma （n=1） and osseous neuroendocrine tumour （n=1）. Images showed erose or osteolytic bone erosions. Huge soft masses surrounding bone were showed in 16 cases. The soft masses were inapparent in 4 cases of multiplemyeloma. The size of soft masses surrounding bone was more than the degree of bone desturction in 13 cases. Conclusion There is more myelopathic tumor than osseous tumor in primary malignant tumor of ilium. Comparing the size of soft masses with the degree of bone desturction is useful for differentiating between myelopathic tumor and osseous tumor.
