目的:探讨腰大肌病变的影像诊断方法及其价值。方法:回顾性分析临床和病理证实的腰大肌病变47例,对腰大肌病变的CT及MRI征象进行分析。结果:18例腰大肌结核病变中均可见相邻胸、腰椎椎体骨质及椎间盘破坏并受累腰大肌肿胀;6例腰大肌脓肿内见多房影、分隔影或气体影;腰大肌良性肿瘤1例,转移瘤11例,其他恶性肿瘤3例,恶性肿瘤表现为腰大肌不规则肿胀、隆起,内见大片状坏死区,增强后不均匀强化;血肿6例,密度混杂,可见团块状高密度影;腰大肌萎缩2例,腰大肌体积均匀缩小。结论:多层螺旋CT和MRI检查对腰大肌病变的诊断有一定的价值,对查找原发病灶、临床诊断和制定治疗方案均有重要的指导意义。
Objective: To explore the imaging diagnosis of psoas muscle lesions and its value. Methods: Forty-seven cases of psoas muscle lesions proved clinically and pathologically were retrospectively analyzed. CT and MRI signs of psoas muscle lesions were analyzed. Results: In all 18 cases of psoas muscle lesions, the adjacent thoracic and lumbar vertebral bone and disc were destroyed and the psoas was inflated. Six cases of psoas muscle abscess were found with multifarious shadow, septum shadow or gas shadow. 1 case of benign large myoma, 11 cases of metastatic tumor and 3 cases of other malignant tumors. Malignant tumors showed irregular enlargement and bulging of the psoas muscle, large necrosis of the lesion, enhanced heterogeneity, 6 cases of hematoma, Mixed, visible mass-like high-density shadow; psoas muscle atrophy in 2 cases, the average size of psoas narrowed. Conclusion: MSCT and MRI have some value in the diagnosis of psoas muscle lesions. It is of great significance in finding primary lesions, clinical diagnosis and treatment planning.
