摘要
目的:探讨骨内脂肪瘤的X线及CT表现,提高其诊断准确率。方法:收集6例经病理证实的骨内脂肪瘤的X线及CT影像资料,结合文献对其临床、病理及影像表现进行回顾性分析。结果:6例均为单发病灶,其中1个病灶位于肩胛冈、1个病灶位于第四腰椎下关节突、3个病灶位于股骨头、1个病灶位于跟骨。X线平片表现为边界清或不清的圆形、类圆形或不规则形透亮区,可伴硬化缘。CT图像上病灶表现为圆形、类椭圆形或不规则形脂性密度区,CT值为-3 5～-110HU,其中1例病灶中央见结节状钙化,病灶最大径为1.8～2.6cm。边缘不规整,伴有厚薄不等的硬化边。结论:X线平片有助于显示骨内脂肪瘤的发生部位,而CT检查能够在术前对其做出定性诊断,从而为临床制定治疗方案提供影像学依据。
Objective：To expore the X-ray and CT features of the intraosseous lipoma and to improve the accuracy of diagnosis.Methods：The X-ray and CT features of intraosseous lipoma confirmed by surgical pathlogy in 6 cases were retrospectively studied and the literatures with intraosseous lipoma of domestic and abroad were reviewed.Results：Single lesions were showed in 6 patients of the six cases with intraosseous lipomas,one located in the scapular spine one in the inferior articular process of fourth lumbar vertebra,three in the femoral head,and one in the calcaneus,respectively.All foci of infection were spherical shape,ova-shape or irregular radiolucent area on X-ray and adipose tissue area with thin or thick sclerotic rim on CT images.The fat attenuation values within the lesion were in the range from-35 HU to-110 HU.Focal intralesional calcification in the center was present in 1 focus.Their longest diameter ranged from 1.8 cm to 2.6 cm.Conclusion：The X-ray manifestations of intraosseous lipoma were helpful for diagnosing location,CT could be provided the qualitative diagnosis for the intraosseous lipoma before operation,and CT provides the imaging gist to establish the treatment project as soon as possible.
