Abstract

We retrospectively evaluated pelvic magnetic resonance imaging including diffusion-weighted imaging (DWI) of 16 ovarian lesions (5 adenocarcinofibromas, 2 borderline adenofibromas, and 9 benign adenofibromas). All adenocarcinofibromas were detected as large solid areas of strong high signal on DWI, and seven of nine benign adenofibromas and both borderline adenofibromas demonstrated no areas of high signal or small areas of weak high signal. Solid components that appear as areas of strong high signal on DWI might represent a characteristic finding of adenocarcinofibromas.

摘要

我们回顾性评估了16例卵巢病变（5例腺纤维癌、2例交界性腺纤维瘤和9例良性腺纤维瘤）的盆腔磁共振成像，包括扩散加权成像（DWI）。所有腺纤维癌在DWI上均表现为大片状实性区域的高信号，9例良性腺纤维瘤中的7例以及2例交界性腺纤维瘤均未显示高信号区域或仅有小片状弱高信号区域。在DWI上表现为高信号区域的实性成分可能是腺纤维癌的特征性表现。
