摘要： 目的 探讨盆腔侵袭性血管粘液瘤(AA)的影像特征及其与盆腔实体肿瘤影像的初步鉴别。 方法 收集2012年4月至2020年5月具有术前影像学检查的AA患者6例(AA组)以及具有相似临床和影像表现的盆腔肿块待诊患者14例(对照组)的资料,以病理学诊断为金标准,对其临床及影像资料进行回顾性分析和鉴别,Fisher精确检验用于AA组和对照组的统计学分析。 结果 AA组中,6例(6/6)T2WI均表现为高信号,增强扫描5例(5/6)明显强化,1例(1/6)中度强化,内部均有“分层样”或“漩涡样”低信号和弥散受限,其中5例(5/6)跨盆膈生长延伸至会阴,3例(3/6)表现出“手指样”突起,3例(3/6)合并囊变。对照组中血管肌纤维母细胞瘤与AA组影像表现最为相似。鉴别时,肿块跨盆膈延伸会阴(P<0.001)、“漩涡样”或“分层样”表现(P<0.001)与对照组之间的差异具有统计学意义。 结论 AA在MRI上具有一定的影像特点,发生于女性的盆腔及会阴区,出现特征性“分层状”或“漩涡样”改变的软组织肿瘤应该考虑AA的可能。

Abstract: Objective To explore the imaging characteristics of pelvic aggressive angiomyxoma(AA)and to differentiate it from other pelvic masses. Methods The clinical and imaging data of 6 AA patients AA group and 14 patients with pelvic masses(controls)who had similar clinical and imaging manifestations treated during April 2012 and May 2020 were retrospectively analyzed. Fishers exact test was used for statistical analysis. Results In the AA group, all cases showed high signal on T2WI. Contrast-enhanced scan showed significant enhancement in 5 cases, and moderate enhancement in 1 case. “Layering” or “swirling” low signals and diffusion restriction were observed in all cases. The angiomyxoma crossed the pelvic diaphragm and extended to perineum in 5 cases, showed “finger-like” projections in 3 cases, and had cystic changes in 3 cases. In the control group, the imaging manifestations of angiomyofibroblastoma(AMF)were the most similar to those of AA group. There were significant differences in the neoplasm crossing the pelvic diaphragm and extending to the perineum(P<0.001), and “layered” or “swirled” signals(P<0.001)between the two groups. Conclusion AA has certain imaging characteristics on MRI, commonly arising in the pelvic cavity and perineum in females. “Layered” or “swirled” signals in soft tissue neoplasms may indicate the presence of AA.
