卵巢表面浆液性交界性乳头状瘤MRI表现及临床病理对照

MRI Findings and Clinicopathologic Analysis of Ovarian Serous Surface Papillary Borderline Tumor

目的通过分析卵巢浆液性表面交界乳头状性瘤(serous surface papillary borderline tumor,SSPBT)的MRI特征并与病理对照,探讨MRI对SSPBT诊断和分期价值。方法回顾性分析并总结19例经手术病理证实的SSPBT的MRI表现,并与病理对照,分析MRI对SSPBT的诊断准确率,对卵巢外腹膜、网膜、淋巴结和输卵管侵犯及转移情况显示效能。结果19例患者共有32个SSPBT(其中双侧14例,单侧5例)。MRI特征包括包绕或部分包绕卵巢的囊实性肿块,实性成分表现为围绕中央分支结构的乳头。MRI对SSPBT卵巢外腹膜、网膜、淋巴结和输卵管非浸润性种植诊断的准确性分别为84.2%、78.9%和94.7%。结论熟悉SSPBT的MRI特征有助于放射医生作出正确诊断和分期,为临床治疗方案的制定提供影像学依据。

Objective To investigate the value of MRI in diagnosis and staging of ovarian serous surface papillary borderline tumor(SSPBT)through comparison with clinicopathological findings.Methods MRI findings of 19 patients with surgical and pathological proven SSPBT were reviewed retrospectively and compared with clinicopathological features.The diagnostic accuracy of MRI on SSPBT was analyzed,and the efficacy of MRI on invasion and metastasis of peritoneum,omentum,lymph node and fallopian tube outside ovary was analyzed.Results A total of 32 SSPBT lesions were detected in the 19 cases including 14 patients with bilateral lesions and 5 patients with unilateral lesion.MRI features include a cystic solid mass that wraps or partially wraps the ovary.The solid component appears as a nipple surrounding a central branch.Accuracies of MRI in diagnosis of peritoneal,omentum and lymph node non-infiltrating implant were 84.2%,78.9%and 94.7%,respectively.Conclusion Familiarity with MRI features of SSPBT is helpful for radiologists to make correct diagnosis and staging,and to provide imaging basis for the formulation of clinical treatment plans.
