摘要
目的分析创伤性关节积脂血征的CT表现特点,探讨CT对创伤性关节积脂血征的诊断价值。方法回顾性分析20例创伤性关节积脂血征患者的临床和CT资料,其中膝关节14例,髋关节4例,肩关节2例。所有患者均于受伤后1h～3d内行CT检查,观察关节内骨折及其关节积脂血征的CT表现。结果 20例创伤性关节积脂血征患者均存在关节内骨折,创伤性关节积脂血征的CT表现为关节囊内特征性的脂肪密度或脂-液平面,后者上层呈脂肪样低密度影,下层为液体样低密度影。结论创伤性关节积脂血征常与关节内骨折并存,临床依据其CT特征性脂肪密度即可明确诊断。
Objective To analyze the CT features of traumatic lipohemarthrosis. Methods The clinical and CT data of 20 patients with traumatic lipohemarthrosis （14 knees, 4 hips and 2 shoulders） were reviewed. CT was performed at 1 hour to 3 days after trauma. CT findings of the intra-articular fractures and traumatic lipohemarthrosis were recorded. Results In all 20 patients, the lipohemarthrosis appeared as fat density or fat-fluid levels in the joints. The superior and inferior bands of fat-fluid level were fat and fluid densities, respectively. Conclusion Traumatic lipohemarthrosis is associated with intra-articular fractures with characteristic CT appearance.
