| 目的 总结分析侵袭性血管黏液瘤(AAM)的CT及MRI影像学特点，提高其诊断能力。方法 收集本院病理证实为AAM患者3例(均为女性患者)，应用256iCT、3.0T MR平扫及增强扫描，并对病灶大小、位置、形态、密度与信号和强化方式进行总结分析。结果 3例AAM患者，病灶位于下腹、盆腔及会阴部；直径＞15cm 1例，直径3-7cm 2例；3例均边界清楚，钻孔样生长1例；CT平扫稍低密度3例，T2WI不均质稍高信号1例/高低混杂信号2例；出现囊变1例； T2WI及MR增强扫描呈现漩涡征2例；CT增强渐进性强化3例、分层样改变1例、小血管断面强化1例。结论 AAM具有一定影像特征性，T2WI及MR增强呈漩涡征、CT增强分层样及小血管断面强化改变，有助于提高对该病的诊断。 |

| Objective to analyze CT and MRI features of aggressive angiomyxoma(AAM),which is a rare interlobular tumor that usually occurs in young women"s pelvic and perineal regions.Methods three cases of AA patients (all female patients) were collected in our hospital.To observe the lesion size, location, texture, morphology, enhancement pattern and other manifestations and record and analyze them.Results there were more women with AA than before. CT and MRI had certain imaging features, and some showed mild enhancement at early stage and obvious enhancement at late stage. In this paper, we also found that the enhancement of small blood vessels in some cases may be related to its pathological characteristics, so it can be considered as one of its imaging characteristics. |
