卵巢囊性病变的MRI诊断与术式选择(附24例分析)

MRI diagnosis of ovarian cystic tumor and the choose of the operational ways

目的:探讨卵巢囊性病变的MRI表现特点及诊断价值,并分析其手术方式。方法:回顾性分析24例经手术病理证实的24个卵巢囊性病变的MRI表现,结合病理对照讨论其术前诊断及术式选择。结果:6例卵巢单纯囊肿,T1WI呈低信号,T2WI呈高信号;4例巧克力囊肿,MRI表现信号不均匀,有亚急性和慢性出血的MRI表现;5例为囊性畸胎瘤,T1WI呈低信号及高信号(脂肪),T2WI呈高信号及低信号(骨骼与牙齿);5例炎性肿块,表现为T1WI呈稍低信号、T2WI呈稍高信号;4例囊腺瘤,T1WI呈稍低信号,T2WI呈稍高信号,其中4例于肿块内见软组织信号影。结论:MRI作为一种多参数的无创性诊断方法,对卵巢囊性病变的定性及术式选择有重要意义。

Objective To evaluate the characteristics and diagnostic value of MRI in ovarian cystic tumor and the choose of the operational ways. Method MRI images of 24 ovarian cystic tumor in patients proved by surgery and pathology were analyzed retrospectively.The MRI characteristics of their images were discussed correlating to their pathological findings to discuss the choose of operational ways. Results 6 cases were pure cystoma,which manifested low signal in T1WI and high signal in T2WI;4 cases were chocolate cystoma, whose signals were not uniform,the same as the manifestations of subacute or chronic hemorrhage;5 cases were proved cystoma teratoma, which showed low and high signal(fat) in T1WI, high and low signal(bone and teeth) in T2WI;5 cases showed inflammatory mass, which showed little low signal in T1WI and little high signal in T2WI; 4 cases were proved cystoadenoma,which showed little low signal in T1WI and little high signal in T2WI, soft issue signal was seen in 4 cases. Conclusion MRI imaging examination can distinctly show the anatomy structure of the ovarian tumor with no hurt and provide effective information for the choose of operational ways.
