摘　　要：目的:探讨骨样骨瘤的影像学表现特点及其诊断价值。方法:回顾性分析24例经手术病理证实的骨样骨瘤的临床及影像学资料,分析X线、CT和MRI对瘤巢及瘤巢周围改变的显示能力。结果:24例病灶均表现为一圆形或卵圆形的透亮瘤巢,直径为0.3～1.8 cm,其周围有不同程度的骨质硬化、骨膜反应、软组织和骨髓水肿或关节腔积液。X线、CT及MRI对瘤巢显示率分别为83.3%(20/24)、100%(12/12)及75%(6/8)。结论:瘤巢是诊断骨样骨瘤的特征性征象,CT是诊断骨样骨瘤的最佳方法,X线或MRI需结合CT才能做出准确诊断。Objective To explore the characteristics and diagnostic value of imaging in osteoid osteoma.Methods The clinical and imaging data of 24 patients with osteoid osteoma confirmed by surgical pathology were analyzed retrospectively.The ability of imaging in demonstrating the change of nidi and the surrounding reaction were analyzed.Results A circular or oval lucency nidus was demonstrated in all 24 cases,the diameters of nidi were ranged from 0.3 to 1.8 cm,different bone sclerosis,periosteal reaction,soft tissue and bone morrow edema or distinct effusion of joint were showed surround the nidi.The detective rates of X-ray,CT and MRI for nidi were 83.3%(20/24),100%(12/12)and 75%(6/8),respectively.Conclusion Nidus may be the most characteristic manifestation and CT may be the best method for diagnosing osteoid osteoma.
