| 目的 探讨骨膜下型骨样骨瘤的X线、CT和MRI表现。方法 回顾性分析经手术病理或随访证实的骨膜下型骨样骨瘤6例,其中男4例,女2例。年龄15~36岁,平均24岁。所有病例均行X线检查,同时行CT检查者3例,行MR检查者1例,3种检查方法都进行者1例。结果 5例病瘤巢表现为弧形骨陷窝,口径为6~16 mm,深为5~10 mm,其周围骨质硬化不明显;1例瘤巢表现为骨骼表面小丘状软组织影。影像学检查均清楚显示瘤巢。结论 影像学检查是发现骨膜下型骨样骨瘤的瘤巢的重要方法,多切面X线投照对于发现瘤巢很有价值。 |

| Objective To study the X-ray, CT, and MR imaging findings in subperiosteal osteoid osteoma. Methods Six cases of subperiosteal osteoid osteoma proved by surgical pathology or call upon, including 4 males and 2 females, aged 15－36 years (mean 24 years). The imaging findings of subperiosteal osteoid osteoma in 6 patients, were retrospectively analyzed. Among the 6 cases, all patients had plain films, 3 were imaged with CT scanning, 1 with MR imaging, and 1 with all three techniques. Results The imaging manifestations of subperiosteal osteoid osteoma revealed local depressed of the cortex nidus, with little bone sclerosis around the nidus for five patients, and showed small hillock parenchyma-rumor for one. The caliber ranged from 6 mm to 16 mm, and the depths ranged from 5 mm to 10 mm. All nidus showed with the imaging techniques. Conclusion The imaging techniques is an important method for showing the nidu in subperiosteal osteoid osteoma, which is valuable for plain film radiography in many ways. |
