成熟的囊性畸胎瘤由分化良好的三胚层构成,由于皮肤成份为主,又称为“皮样囊肿”。通常为良性,恶变率仅为1％～2％。最常见的恶变是鳞癌。作者报道了5例女性患者6个成熟囊性畸胎瘤恶变的MR表现并做了简要的回顾。 病人年龄46～76岁,经手术证实为6个成熟囊性畸胎瘤(1例为双侧)恶变。术前行MRI检查,层厚5mm,间隔2.5mm,SE序列T_1WI(TR/TE=600/15～20)、T_2WI(TR/TE=2000/60～90),2例行增
Mature cystic teratoma consists of well-differentiated three germ layers, due to the composition of the skin, also known as “dermoid cysts.” Usually benign, malignant rate of only 1% to 2%. The most common malignant is squamous cell carcinoma. The authors report MR findings of 6 malignant cystic teratoma malignancies in 5 female patients and briefly reviewed. Patients aged 46 to 76 years old, confirmed by surgery as 6 mature cystic teratoma (1 case of bilateral) malignant transformation. Preoperative MRI examination, layer thickness 5mm, interval 2.5mm, SE sequence T_1WI (TR / TE = 600/15 to 20), T_2WI (TR / TE = 2000/60 to 90)
