侵袭性血管粘液瘤是一种罕见的骨盆和会阴的非转移性软组织肿瘤，几乎只发生于成年女性。它浸润局部，局部复发的风险很高。对于有症状的患者，推荐的治疗方法是广泛切除无肿瘤边缘，并密切术后监测。在这里，侵袭性血管粘液瘤在一个成年男性的情况下，它出现在阴囊超过12个月。肿瘤在t1加权MRI图像上显示中等信号。对比增强t1加权图像显示较好的增强效果。大面积切除肿瘤。手术标本尺寸为7 × 5 × 5厘米，重80克。肿瘤表面光滑，切面呈胶状。肉眼可见，它被胸膜样膜包裹，呈指状突出。显微镜下，切片显示许多不同大小的有壁血管，胶原原纤维，松散的粘液样背景和梭形间质细胞。MRI及CT表现为瘤壁血管瘤及黏液瘤性质。据作者所知，这是第一份描述阴囊血管粘液瘤MRI表现的报告。
Aggressive angiomyxoma is a rare and nonmetastasizing soft tissue tumor of the pelvis and perineum and occurs almost exclusively in adult females. It infiltrates locally and has a high risk of local recurrence. Recommended treatment of the symptomatic patient is wide excision with tumor-free margins and close postoperative monitoring. Herein, a case of aggressive angiomyxoma in an adult male is described, which arose in the scrotum over 12 months. The tumor showed an intermediate signal on T1-weighted MRI images. Contrast-enhanced T1-weighted images showed good enhancement. Wide excision of the tumor was performed. The Surgical specimen measured 7 x 5 x 5 cm in size and weighed 80 g. The tumor's surface was smooth and had a gelatinous cut surface. Grossly, it was encapsulated with a pleura-like membrane and had a finger-like projection. Microscopically, sections showed many walled vessels of various sizes, collagen fibrils, a loose myxoid background, and spindle stroma cells. MRI and CT showed the angiomatous and myxomatous nature of the tumor wall. To the authors' knowledge, this is the first report to describe MRI findings in scrotal angiomyxoma.
