Twelve patients with stress fracture were examined by computed tomography (CT). Computed tomography appeared less sensitive than conventional radiographs in visualizing the cortical and periosteal changes. However, CT revealed endosteal callus formation of varying degrees even in cases with minor plain film findings. Two types of endosteal reaction were observed: a general endosteal thickening and a slight local bridge-formed callus. Density of the bone marrow cavity was increased in 10 cases. Soft tissue edema around the lesion was also seen, especially when the tibia was involved. The etiology of these findings is discussed, together with the differential diagnosis of malignant bone or soft tissue tumors.
对12例应力性骨折患者进行了计算机断层扫描（CT）检查。在观察皮质和骨膜变化方面，计算机断层扫描似乎不如传统X线片敏感。然而，即使在平片表现轻微的病例中，CT也显示出不同程度的骨内膜骨痂形成。观察到两种类型的骨内膜反应：一种是普遍的骨内膜增厚，另一种是轻微的局部桥状骨痂。10例患者骨髓腔密度增加。病变周围还可见软组织水肿，尤其是累及胫骨时。本文讨论了这些表现的病因，以及恶性骨或软组织肿瘤的鉴别诊断。
