We report the case of a 9.5-year-old boy who underwent sonographic and radiographic examinations because of knee pain. Two fibrous cortical defects were discovered, in his right femur and left tibia; the femoral lesion was seen more easily on sonography than on radiography. On gray-scale sonography, the lesions were characterized as a scalloped indentation of the cortical surface containing hypoechoic soft tissue. On color Doppler sonography, discrete vessels were found at the periphery and within the substance of the lesions, and on spectral Doppler analysis, low-resistance arterial flow was detected in those vessels. Follow-up examinations performed 10 and 19 months after our initial examination showed signs that the lesions were healing. The diagnosis of fibrous cortical defect was suggested by the gray-scale and Doppler sonographic characteristics and confirmed on radiography. Although radiography is required to document these lesions if found incidentally on sonography, follow-up examinations using only sonography may be feasible.
我们报告了一名9.5岁男孩的病例,该男孩因膝关节疼痛接受了超声和放射检查。在他的右股骨和左胫骨发现了两个纤维性皮质缺损;股骨病变在超声检查中比在放射检查中更容易看到。在灰阶超声上,病变表现为皮质表面的扇形凹陷,内含低回声软组织。在彩色多普勒超声上,在病变周边及内部发现了离散的血管,频谱多普勒分析显示这些血管内有低阻力动脉血流。在我们初次检查后10个月和19个月进行的随访检查显示病变有愈合迹象。纤维性皮质缺损的诊断由灰阶和多普勒超声特征提示,并经放射检查证实。虽然如果超声偶然发现这些病变需要放射检查来记录,但仅使用超声进行随访检查可能是可行的。
