螺旋CT对骨样骨瘤的诊断价值探讨

摘要

Objective To analyze the value of the spiral CT in the diagnosis of osteoid osteoma. Methods 12 patients with osteoid osteoma proved by surgical pathology and the imaging of X-ray and spiral CT scan were retrospectively analyzed. Results Among the 12 cases, 6 cases of lesions in the femur and 2 cases in the tibia, 2 cases in the humerus and 2 cases in the other parts. CT showed the nidus and surrounding of the nidus with the different levels of hardening, and the nidus showed a round or oval translucent area with a diameter of 3~16mm. mean 9. 0mm, 7 cases wiht the center calcification. Conclusion Nidus is the key to diagnosis of osteoid osteoma, spiral CT scan shows nidus is the preferred method of examination in the diagnosis of osteoid osteoma.%目的 探讨螺旋CT在骨样骨瘤中的诊断价值.方法 对12例经病理证实且行X线和螺旋CT扫描检查的骨样骨瘤病人的影像学表现进行回顾性分析.结果 12例患者中,病灶位于股骨6例、胫骨2例、肱骨2例和其它部位2例.CT表现为瘤巢及其周围形成程度不同的反应性骨质硬化,瘤巢表现为一圆形或卵圆形的透亮区,直径为3～16mm,平均9.0mm,中心有钙化7例.结论 瘤巢是确诊骨样骨瘤的关键；螺旋CT扫描是显示瘤巢的首选检查方法,在骨样骨瘤诊断中具有重要的价值.
