A 39-year-old man who presented with right knee pain following trauma was found to have a radiographically-occult fracture of the lateral tibial condyle on magnetic resonance (MR) imaging. The intra-articular fracture was seen as a curvilinear area of hypointensity on both T1- and T2- weighted MR images, with surrounding bone bruising. The MR appearances of occult fractures and bone bruising, and the role of MR imaging in the detection of these injuries in various other regions, such as the ankle, hip, elbow and wrist, are discussed.
一名39岁男性在创伤后出现右膝疼痛，磁共振成像（MR）检查发现其外侧胫骨髁有影像学隐匿性骨折。关节内骨折在T1加权和T2加权MR图像上均表现为低信号的曲线状区域，并伴有周围骨挫伤。本文讨论了隐匿性骨折和骨挫伤的MR表现，以及MR成像在检测踝关节、髋关节、肘关节和腕关节等其他不同部位这些损伤中的作用。
