【摘要】：目的探讨腰椎间盘脱出髓核游离的MRI表现与手术病理特征,提高对该病的诊断水平。方法回顾性分析经手术病理证实的38例腰椎间盘脱出髓核游离患者的临床表现、MRI特征、手术病理资料。结果 38例椎间盘脱出髓核游离发生在L3~4椎间盘2例,L4~5椎间盘17例,L5~S1椎间盘19例。38例中髓核上行游离11例,下行游离17例,平行游离10例。游离髓核呈圆形或椭圆形,在T1WI游离髓核以等信号为主(38例),T2WI为等信号(22例)或稍高信号(16例)。19例行增强扫描显示环状强化(17例)或混杂不均等强化(2例)。结论 MRI检查对腰椎间盘脱出髓核游离诊断准确率高;髓核周围强化越明显,提示炎性反应及黏连越严重,手术分离难度越大。
[Abstract]:Objective to investigate the MRI features and surgical and pathological features of free nucleus pulposus of lumbar intervertebral disc prolapse (LIDP), and to improve the diagnostic level of the disease. Methods the MRI features and pathological data of 38 patients with free nucleus pulposus from lumbar intervertebral disc prolapse proved by operation and pathology were analyzed retrospectively. Results the dissociation of prolapse of intervertebral disc occurred in L3 / 4 intervertebral disc in 2 cases and in L4 / 5 intervertebral disc in 17 cases (n = 19). Among them, there were 11 cases of ascending dissociation of nucleus pulposus, 17 cases of descending dissociation and 10 cases of parallel dissociation. The free nucleus pulposus was round or elliptical. In T _ 1WI, iso-signal was dominant in the nucleus pulposus (n = 38), isointense on T _ 2WI (n = 22) or slightly hyperintense (n = 16). 19 cases showed circular enhancement (n = 17) or mixed unequal enhancement (n = 2). Conclusion MRI is highly accurate in the diagnosis of free nucleus pulposus from lumbar intervertebral disc protrusion, and the more obvious the enhancement of nucleus pulposus is, the more serious the inflammatory reaction and adhesion are, the more difficult the operation is.
