摘　　要：目的探讨MRI在诊断卵巢表面浆液性交界性肿瘤(serous borderline ovarian tumor,SBOT)中的应用价值。方法选取6例经手术病理证实为SBOT患者,分析临床特点及MRI特征。结果6例患者中3例为双侧发病,1例左侧,2例右侧,所有病灶MRI均表现为包绕或部分包绕卵巢的囊实性肿块,囊性成分为长T_(1)、长T_(2)水样信号,实性成分表现为分支状结构伴有乳头状突起,呈等长T_(1)、稍长T_(2)信号,增强后实性成分显著强化,囊性成分无强化,其中术前诊断4例伴有盆腔内腹膜种植均由病理证实。结论SBOT好发于育龄期妇女,掌握MRI特征表现,有助于术前准确判断及分期,对临床手术方式的选择具有指导意义。Objective To investigate the value of MRI in diagnosis of serous borderline ovarian tumor(SBOT).Methods MRI features of 6 patients with surgical and pathological proven SBOT were analyzed retrospectively and compared with pathology.Results The median age of 6 patients was 33.3 years old.With respect to the pathology,3 cases had SBOT in both ovaries,1 case in left ovary and 2 case in right ovary.MRI features showed the cystic solid mass that wrapped or partially wrapped the ovary.The cystic part of the mass showed hypointensity on T_(1)WI and hyperintensity on T_(2)WI.The solid components appeared as branched structures with papillary protrusions,showed isointensity on T_(1)WI and T_(2)WI.With contrast agent,the solid component showed obvious enhancement.Among them,4 cases of preoperative diagnosis with intrapelvic peritoneal implantation were confirmed by pathology.Conclusion SBOT tends to occur in women of childbearing age.Familiarity with MRI features of SBOT is helpful for radiologists to make correct diagnosis and staging,and to guide the formulation of clinical surgery plan.
