A 28-yr-old woman presented with both hip pain that started sequentially during the peripartum period. Diagnosis of transient osteoporosis of the hip (TOH) was made based on typical findings of plain radiographs and magnetic resonance images. The subchondral trabeculae of the femoral head were evaluated on serially taken coronal multiplanar reformation computerized tomogram images. At 4 weeks after pain onset, marked decrease in the sclerotic density with irregular discontinuation was observed in the primary compression trabeculae. At 12 weeks, a focal area of irregular thickening of trabeculae was observed. At 20 weeks, sclerotic density of trabeculae recovered markedly and the focal area of irregular trabecular thickening disappeared. At 1 yr, subchondral trabeculae recovered almost completely. The evidence of subchondral trabecular injury was observed in the femoral heads of TOH.
一位 28 岁女性双侧髋关节疼痛就诊，疼痛始于围产期。根据 X 线和平扫磁共振成像的典型表现，诊断为一过性髋关节骨质疏松症（TOH）。对连续冠状多平面重建计算机断层扫描图像进行股骨头软骨下小梁评估。疼痛发作后 4 周，主压缩小梁的硬化密度明显降低，不规则中断。12 周时，观察到小梁不规则增厚的局灶性区域。20 周时，小梁硬化密度明显恢复，小梁不规则增厚的局灶性区域消失。1 年后，软骨下小梁基本完全恢复。TOH 患者的股骨头可见软骨下小梁损伤的证据。
