【摘要】：目的研究髂腰肌囊扩张影像学特点并分析相关因素对其影响。方法回顾性分析60例经关节镜手术或穿刺活检证实的髂腰肌囊扩张患者(扩张组)临床资料及CT、MR图像,同时选取60例无髂腰肌囊扩张的患者作为对照组,应用Mann-Whitney U和Wilcoxon W检验分析包括性别、年龄、单双侧、是否合并其他髋关节病变等因素对该病的影响。结果扩张组与对照组分为男33例(55.0%)、36例(60.0%),女27例(45.0%)、24例(40.0%);扩张组年龄16~66岁,平均(41.6±5.7)岁,其中18岁4例(6.7%),≥18岁56例(93.3%),对照组年龄16~64岁,平均(42.6±6.2)岁,其中18岁6例(10.0%),≥18岁54例(90.0%)。扩张组、对照组分为单侧48例(80.0%)、50例(83.3%),双侧12例(20.0%)、10例(16.7%)。扩张组合并有股骨头坏死28例(46.7%),骨性关节炎26例(43.3%),正常者6例(10%),对照组合并髋关节病变50例(83.3%),正常者10例(16.7%)。两组年龄、单双侧、是否合并其他髋关节病变均差异有统计学意义(P0.05),两组性别差异无统计学意义(P0.05)。CT、MR图像特点:扩张的髂腰肌囊呈囊性低密度,MR呈长T1、长T2水样信号,脂肪抑制像呈高信号,边缘多光滑锐利,呈水滴样或卵圆形改变,其后缘为关节囊,内侧缘为股动静脉。结论髂腰肌囊扩张无明显性别差别,常见18岁以上成年人,大多数为单侧发生,常合并有股骨头坏死、骨性关节炎等髋关节疾病,CT、MR为其首选的检查手段,可对该病作出明确诊断。
[Abstract]:Objective to study the imaging features of iliopsoas bursa dilatation and to analyze the influence of related factors on it. Methods the clinical data and CT Mr images of 60 patients with iliopsoas bursa dilatation (dilated group) confirmed by arthroscopy or puncture biopsy were retrospectively analyzed. At the same time, 60 patients without iliopsoas sac dilatation were selected as control group. Mann-Whitney U and Wilcoxon W test were used to analyze sex, age, unilateral and bilateral. Results the patients in the expansion group and the control group were divided into three groups: 33 males (55.0%) and 36 cases (60.030%), 27 females (45.0%) and 24 cases (40.0%), the age of the expansion group was 1666 years (mean 41.6 卤5.7) years. Among them, 4 cases were 18 years old, 56 cases were above 18 years old, 56 cases were above 18 years old. The control group was 1664 years old with an average age of 42.6 卤6.2 years, of which 6 cases were 18 years old and 54 cases were over 18 years old. The control group was divided into 48 cases with unilateral 80. 0 and 50 with 83.3, 12 with bilateral 20. 0 and 10 with 16. 7. Dilation and 28 with necrosis of femoral head, 26 with osteoarthritis, 46 with 43.3, 6 with normal, 50 with hip lesions, 10 with normal, 10 with 16. 7. The age of the two groups were unilateral and bilateral. There were significant differences in other hip lesions between the two groups (P 0.05). There was no significant difference between the two groups. The enlarged iliopsoas bursa presented long T 1, long T 2 water like signal and high signal intensity in fat suppressor imaging, and the enlarged iliopsoas bursa showed long T 1, long T 2 water like signal and high signal intensity. The margin of iliopsoas muscle sac is more smooth and sharp, with water droplets or oval changes, the posterior margin is the articular capsule, and the medial margin is femoral arteriovenous. Conclusion there is no significant gender difference in the dilatation of iliopsoas muscle sac, most of which occur on one side in adults over 18 years of age. CTMR is the first choice for the diagnosis of hip joint diseases such as osteoarthritis and necrosis of femoral head.
