摘　　要：目的:探讨颅骨广泛性病变的X线、CT表现及鉴别要点。方法:总结分析经手术病理及穿刺活检证实或征像典型的颅骨广泛性病变7例。结果:7例中,多发骨髓瘤3例;棕色瘤及畸形性骨炎各2例。其影像特点如下:棕色瘤:囊性变或广泛细小颗粒状低密度影;畸形性骨炎:棉花团样高密度影;多发性骨髓瘤:圆形穿凿样、虫蚀状低密度影。7例中部分病变有其相应的特征性临床表现。结论:X线平片对于诊断和整体性观察颅骨广泛性病变有一定价值;CT检查能显示病灶内部结构颅骨骨质破坏的范围及边缘情况,但部分病变则需结合其特征性临床表现,以提高颅骨广泛性病变的诊断及鉴别诊断。Objective：To investigate the X-ray and CT manifestations of extensive lesions of the skull and the discriminating gist from other lesions. Methods：7 cases with the extensive lesions of the skull confirmed by pathology of puncturafion and operation or typical imaging manifestations were retrospectively analysed. Results： Of 7 cases, there are skull malignant tumois in 3 cases and skull tumor like lesions in 4 cases. 3 cases of malignant tumors are all multiple myeloma. Tumor like lesions include brown tumors and osteitis deformans of 2 eases respectively. Concluslon：X-ray plain films have some value to diagnostic the extensive lesions of the skull and to observe the lesions entirely. CT examination could not only find the precise location of the lesion, but also disply internal element and construction of it. Circumscription of bone destruction and circumstance of its borderline could also be displayed clearly in CT imaging. To increase accuracy of the diagnosis, the diagnosis of some cases should be done combined with typical clinical manifestation.
