摘要
目的:分析骨样骨瘤的X线和CT表现,探讨64层CT对骨样骨瘤的诊断价值。方法:经手术病理证实的骨样骨瘤19例,男13例,女6例,年龄12～44岁,平均21.5岁。所有病例均行X线检查,同时行CT检查者12例,其中行64层CT检查者4例。分析骨样骨瘤的X线和CT表现,分析2种检查方法对瘤巢和瘤巢周围改变的显示能力。结果:19例病灶均表现为一圆形或卵圆形透亮区,直径0.4～1.7cm(平均10.2cm),其周围有不同程度的骨质硬化,5例周围软组织肿胀。19例中X线平片显示瘤巢14例,12例行CT检查者均清楚显示瘤巢,X线和CT对瘤巢的显示率分别为73.7%(14/19)和100%(12/12)。结论:X线平片是诊断骨样骨瘤的重要检查方法,64层CT结合其后处理技术对发现瘤巢和正确诊断骨样骨瘤有重要价值。
Objective：To analyze the radiography and CT manifestations and to discuss the value of 64-slice spiral CT （MSCT） inthe diagnosis of osteoid osteoma. Methods：Nineteen cases of osteoid osteoma proved by surgery and pathology were collected,including 13 males and 6 females,with the age ranged from 12 to 44 years,the average age was 21.5 years. All of the 19 patients were examined by X-ray plain films and 12 patients had CT scanning,including 4 cases had MSCT. The radiographic and CT findings and the ability of these two modalities in demonstrating the nidus and its surrounding tissues were retrospectively analyzed. Results：The imaging findings of these 19 osteoid osteoma were showed as a round or oval translucent nidus with the diameter ranged from 0.4-1.7cm （average 1.02cm）. Various degree of peripheral bony sclerosis were assessed,soft tissue swelling were shown in 5 cases. Of the 19 patients,the nidus was shown on X-ray plain film in 14 patients and clearly assessed on CT in 12 patients,the rate of demonstrating tumor nidus by radiography and CT was 73.3% （14/19） and 100% （12/12） respectively. Conclusion：X-ray film is still an important examination in the diagnosis of osteoid osteoma,64-slice spiral CT in combination with post-processing techniques had important value in detecting the nidus and correct diagnosis.
