摘要
①目的探讨髂腰肌囊扩张的ＣＴ表现及诊断价值。②方法回顾性阅读经穿刺抽吸或手术病理证实的１５例髂腰肌囊扩张病人的ＣＴ片并记录各种征象。③结果１５例病人扩张的髂腰肌囊均为圆形或卵圆形，内无强化的囊性肿物，位于髋关节囊前方，髂股血管外后方，髂肌（和腰大肌）内侧。１０例表面有厚薄不一的腰大肌肌束覆盖，自上而下逐渐变薄，直至消失。３例沿髋臼或髂骨基底内侧面向上延伸，并突入髂腰肌内。５例延续到髋臼下方，位于耻骨肌前外侧，止于股骨小转子以上，其中３例为倒水滴状。７例行增强扫描，其中５例囊壁呈细线样轻度强化。④结论ＣＴ扫描几乎对所有的髂腰肌囊扩张病人可提示正确诊断。
Objective To study the diagnostic value of CT on enlarged iliopsoas bursa. Methods CT films of 15 patients with enlarged iliopsoas bursa were studied retrospectively. All these patients were positively diagnosed by aspiration of synnovial fluid or surgical operation. Results Enlarged iliopsoas bursa in all the 15 patients appeared as a round or oval cyst and standed posteroexternal to iliac blood vessels and femoral blood vessels, medial to iliac muscle and anterior to hip joint capsule. In 10 cases, the bursas were surrounded or covered by greater psoas muscle bundles, which became thinner and thinner downwards and disappeared at last. The bursas of 3 cases extended upwards along the aectabulum and internal surface of the ilium base, protruding into iliopsoas muscle. In 5 cases, the bursas went downwards, posteromedial to pectineal muscle, three of which looking like an upside down water drop. In 5 out of 7 cases with enhanced contrast CT, the cystic wall demonstrated increased linear density. Conclusion CT scanning can make a positive diagnosis for all patients with enlarged iliopsoas bursa.
