目的探讨骨样骨瘤的影像学表现。方法对经手术病理证实的17例骨样骨瘤的影像学资料和病理进行回顾性分析。所有病例均行X线检查,同时行CT扫描11例、磁共振成像(MRI)扫描4例。分析X线、CT和MRI对瘤巢及瘤巢周围改变的显示能力。结果 X线、CT和MRI检查分别有13例、10例和3例表现为一圆形或卵圆形<2 cm瘤巢,周围有程度不一的骨质硬化、骨膜反应、软组织肿胀。X线、CT和MRI的诊断准确率分别为77%、91%和100%。结论大多数骨样骨瘤有X线特征表现,通过X线检查可得到诊断。CT和MRI扫描易于发现骨样骨瘤的瘤巢,便于确诊本病。
Objective To investigate the imaging findings of osteoid osteoma. Methods The imaging data and pathology of 17 cases of osteoid osteoma confirmed by surgery and pathology were retrospectively analyzed. All cases underwent X-ray examination, while CT scan in 11 cases, magnetic resonance imaging (MRI) scan in 4 cases. X-ray, CT and MRI analysis of neoplasms and neoplasms around the display of changes in ability. Results X-ray, CT and MRI examination were 13 cases, 10 cases and 3 cases showed a round or oval <2 cm nests, surrounded by varying degrees of bone sclerosis, periosteal reaction, soft tissue swelling. X-ray, CT and MRI diagnostic accuracy rates were 77%, 91% and 100%. Conclusion Most osteoid osteomas have X-ray features and can be diagnosed by X-ray examination. CT and MRI scan easy to find osteoid osteoma tumor nests, easy to diagnose the disease.
