卵巢透明细胞癌的MR诊断
Nei Mongol Journal of Traditional Chinese Medicine(2011)
Abstract
目的:分析卵巢透明细胞癌的临床特征和MR表现,以期提高对本病的诊断率.方法:回顾性分析经手术病理证实的11例卵巢透明细胞癌的临床资料和MR表现,所有病例均行盆腔MR平扫及动态增强扫描.结果:11例卵巢透明细胞癌患者平均发病年龄为55岁,2例伴有子宫内膜异位症;11例卵巢透明细胞癌中2例双侧卵巢发病,5例来源于右侧卵巢,4例来源于左侧卵巢.MR表现:囊实性肿块9例,实性肿块2例;囊实性及实性肿块中实性成份信号较均匀,实性肿块边缘较光滑,动态增强扫描显示:动脉期呈轻度不均匀性强化,延迟期呈明显较均匀性强化,动态增强扫描时间-信号强度曲线呈“缓慢上升型”.结论:卵巢透明细胞癌的MR表现有一定的特征性,结合临床表现,有助于提高诊断的正确性.
