Aggressive angiomyxoma is a rare mesenchymal tumor with high rate of local recurrence, found mainly in the pelvis and perineum of women of reproductive-aged group. We present cases of two patients, with emphasis on the magnetic resonance (MR) imaging characteristics. The clinical presentation was nonspecific. MR imaging revealed characteristic "swirl sign" in T2-weighted sequence. Preoperative diagnosis could not be made in the first patient due to a lack of experience about the diagnosis. Preoperative diagnosis was made in the second case and was helpful for the surgeon to excise the mass completely. Aggressive angiomyxoma should be on the top of a differential diagnosis in the appropriate clinical and imaging scenario.
侵袭性血管黏液瘤是一种罕见的间叶性肿瘤，局部复发率高，主要发生于育龄期女性的盆腔和会阴。我们报告两例患者的病例，重点介绍磁共振（MR）成像特征。临床表现不具有特异性。MR成像在T2加权序列上显示出特征性的“漩涡征”。首例患者因缺乏诊断经验而未能进行术前诊断。第二例患者进行了术前诊断，这有助于外科医生完整切除肿块。在合适的临床和影像学表现情况下，侵袭性血管黏液瘤应列为鉴别诊断的首要考虑。
