The authors report the case of a 15-year-old female who presented with a history of vague but constant pain about the medial aspect of her right knee. X-ray established the presence of an expanding lesion in the medial tibial plateau. Computerized axial tomography (CT) and magnetic resonance imaging (MRI) were used in the evaluation of the lesion. The authors compare the preoperative CT and MRI findings with the microscopic histopathology of the amputation specimen and note that the CT scan underestimated the extent of the microscopic tumor boundaries, whereas MRI showed altered activity beyond these boundaries.
作者报告了一例15岁女性病例，该患者右膝内侧有模糊但持续的疼痛病史。X线检查发现胫骨内侧平台有一个正在扩大的病变。采用计算机断层扫描（CT）和磁共振成像（MRI）对该病变进行评估。作者将术前CT和MRI检查结果与截肢标本的微观组织病理学结果进行了比较，发现CT扫描低估了微观肿瘤边界的范围，而MRI显示在这些边界之外有活性改变。
