乳头状突起是上皮性卵巢肿瘤的特征性病理特征，我们试图确定这些结构在MRI上是否具有可识别的特征。对125例患者的数据库进行了检索，这些患者使用盆腔相控阵线圈进行了MRI检查，并对可疑的妇科疾病进行了腹部手术探查，确定了15例患者的MRI报告或病理报告中提到了附件肿块中的乳头状突起。对MR图像进行了审查，以表征乳头状突起的大小、结构和信号强度，病理相关性进行了这些和四个手术标本成像高分辨率技术。病理相关性显示，较大的乳头状突起具有独特的纤维柄结构，支持水肿乳头团，信号强度与T2加权图像上的液体信号强度相似。较小的乳头在T2加权像上表现为中等信号强度的难以描述的囊内投影。所有在体乳头状突起在注射钆喷酸葡胺后增强，乳头状突起在MRI上的表现反映了其组织学结构。
Papillary projections are distinctive pathologic features of epithelial ovarian neoplasms, We sought to determine whether these structures have recognizable features on MRI. A search of a database of 125 patients on whom MRI was performed with pelvic phased-array coil and abdominal surgical exploration was performed for suspected gynecologic disease identified 15 patients who had either MRI reports or pathology reports mentioning papillary projections in an adnexal mass, The MR images were reviewed to characterize the size, structure, and signal intensity of papillary projections, Pathologic correlation was performed on these and on four surgical specimens imaged with high resolution technique. Pathologic correlation showed that larger papillary projections had a distinctive structure of a fibrous stalk supporting clumps of edematous papillae with signal intensity similar to that of fluid on T2-weighted images. Smaller papillae showed nondescript intracystic projections of intermediate signal intensity on T2-weighted images. All papillary projections in vivo enhanced after injection of gadopentetate dimeglumine, Papillary projections have an appearance on MRI that reflects their histologic structure.
