We present the magnetic resonance imaging (MRI) findings in two males clinically diagnosed with iliotibial band friction syndrome (IBFS), a frequent cause of pain in the lateral compartment of the knee. Coronal T2-weighted images with fat saturation show an ill-defined area of high signal intensity in the soft tissues situated immediately below the iliotibial band lateral to the external condyle of the femur. No thickening of the iliotibial band or changes in its signal intensity were observed. Osseous edema and subchondral osseous erosion in the external condyle of the femur were observed in both cases. Pain in the lateral compartment of the knee might be due to multiple causes that should be included in the differential diagnosis and MRI can play a significant role in reaching the definitive diagnosis.
我们展示了两名临床诊断为髂胫束摩擦综合征（IBFS）男性患者的磁共振成像（MRI）结果，该综合征是膝关节外侧疼痛的常见原因。脂肪抑制冠状位T2加权图像显示，在股骨外髁外侧紧邻髂胫束下方的软组织中有一个边界不清的高信号区。未观察到髂胫束增厚或其信号强度改变。两例均观察到股骨外髁骨水肿和软骨下骨侵蚀。膝关节外侧疼痛可能由多种原因引起，这些原因应纳入鉴别诊断，而MRI在明确诊断中可发挥重要作用。
