摘　　要：目的探讨侵袭性血管黏液瘤(AAM)的影像学表现。方法回顾性分析3例经手术病理证实为AAM患者的临床和影像学资料,3例患者均行CT检查,其中1例行MR I检查。结果3例患者均表现为盆腔、会阴或外阴部的软组织肿块,境界清晰,肿块推移但并不浸润邻近结构,其中2例CT增强扫描及MR I的T2W I显示肿块内特征性“旋涡状”和“分层样”结构,且1例复发病灶具有与原发灶相似的影像学表现。3例患者中1例表现为病灶内小囊状低密度。结论AAM的CT和MR I表现具有相对特征性,且MR I较CT更具临床应用价值。Objective To investigate the imaging features of aggressive angiomyxoma . Methods CT findings in 3 patients and MRI finding among one of them With pathologically proved aggressive angiomyxoma were retrospectively analyzed and the relevant literature were reviewed. Results In all the 3 cases, CT and MR imaging demonstrated a well defined mass arising from the pelvis, perineum or vulva. The tumours displaced but did not invade adjacent structures of the pelvic. In 2 cases, there was marked enhancement following injecting contrast materials or T2WI with internal swirling pattern. Recurrent tumour in one case was of similar imaging features to the primary lesion. The small cystiform area could be seen inside the lesion in one case. Conclusion Aggressive angiomyxoma carries certain characteristics in GT and MRI manifestations. MRI is more excellent than GT in delineating the site, shape and the extent of these lesions.
