【摘要】：目的:探讨腹壁子宫内膜异位症的MRI征象及临床特点,探讨MRI的诊断价值。方法:本院39例经病理组织学证实的腹壁子宫内膜异位症患者,经盆腔MRI平扫及增强扫描,回顾性分析其影像表现及临床病理资料。结果:39例腹壁子宫内膜异位症中,大多数患者有剖宫产手术史,仅1例无腹部手术史。34例(87.2%)病灶边界模糊。22例(56.4%)病灶呈实性,T_1WI呈等信号,T_2WI呈混杂信号为主;15例(38.5%)病灶呈囊实性,T_2WI呈高低混杂信号,T_1WI以等低信号为主,其中抑脂T_1WI中有高信号灶为7例;2例(5.1%)病灶呈囊性,T_2WI及T_1WI均呈高信号。囊性病灶增强扫描后强化不明显;实性及囊实性病灶增强扫描后病灶均可见持续性强化,病灶显示更加清晰。结论:结合临床病史及MRI表现特点,能准确诊断腹壁子宫内膜异位症,MRI能准确显示病灶位置、边界、大小及范围,对于临床治疗方案的制定有很大参考价值。
[Abstract]:Objective: to investigate the MRI signs and clinical features of abdominal wall endometriosis and to explore the diagnostic value of MRI. Methods: 39 cases of abdominal wall endometriosis confirmed by histopathology were examined by pelvic MRI plain scan and enhanced scan. Results of 39 cases of abdominal endometriosis, most of them had a history of cesarean section. Only one case with no history of abdominal surgery. 34 cases with 87.2%) the boundary of lesion was blurred. 22 cases (56.4).) the lesions presented solid T 1WI with isointense T 1WI and 15 cases with T 2WI with mixed signal and 15 cases with T 2WI. The lesions showed high and low mixed signal intensity on T 2WI and low signal intensity on T 1WI, and low signal intensity on T 1WI. Among them, 7 cases had hyperintense lesions on T _ 1WI (7 cases) and 2 cases (5.1WI) had high signal intensity on both T _ 2WI and T _ 1WI. The enhancement of cystic lesions was not obvious after contrast enhancement, and continuous enhancement was observed after both solid and solid lesions were enhanced. Conclusion: combined with the clinical history and MRI features, MRI can accurately diagnose the location, boundary, size and range of the lesions in the abdominal wall endometriosis. It has great reference value for the formulation of clinical treatment plan.
