We report a case of intra-articular fracture of the knee joint showing three layers within lipohemarthrosis. Sagittal ultrasonography showed three layers (double fluid-fluid level): a superior hyperechoic layer of fat, an intermediate anechoic layer of serum, and an inferior hypoechoic layer of red blood cells. Horizontal computed tomography imaging demonstrated the same three layers. This is the first case of lipohemarthrosis in which three layers of joint effusion were confirmed by both ultrasonography and computed tomography.
我们报告一例膝关节关节内骨折,其关节积脂血症呈现三层结构。矢状面超声显示三层结构(双液-液平面):上方为高回声的脂肪层,中间为无回声的血清层,下方为低回声的红细胞层。水平位计算机断层扫描成像也显示出相同的三层结构。这是首例通过超声和计算机断层扫描均证实关节积液有三层结构的关节积脂血症病例。
