Intra-articular osteoid osteoma accounts for approximately 13% of all osteoid osteomas and presents as a monoarthropathy. Radiographs commonly do not identify the nidus, and in this event, MRI is likely to be the next imaging investigation. MRI may show a variety of appearances depending upon the age of the lesion. This article illustrates the imaging features of intra-articular osteoid osteoma, with emphasis on MRI. CT remains the investigation of choice for identifying the nidus.
关节内骨样骨瘤约占所有骨样骨瘤的13%，表现为单关节病。X线平片通常无法识别瘤巢，此时，MRI可能是接下来的影像学检查手段。根据病变的年龄，MRI可能表现出多种影像特征。本文阐述关节内骨样骨瘤的影像学特征，重点是MRI。CT仍然是识别瘤巢的首选检查方法。
