1、实用放射学杂志2013年11月第29卷第11期JPractRadiol,Nov.2013,Vol.29,No.11·1807·睾丸肿瘤的临床特点和MRI表现1123411龙德云,陈和平,张联合,柳杰,叶孝权,周涛,陈明安(1武警浙江省总队医院放射科,浙江嘉兴314000;2武警浙江总队杭州医院放射科;3武警浙江总队卫生处;4武警浙江省总队医院病理科)摘要:目的探讨睾丸肿瘤的MRI表现及临床特点,旨在提高对该病的诊断水平。方法回顾性分析36例经手术和病理证实的睾丸肿瘤的临床资料和MRI表现。所有病例均行MRI平扫,其中6例行MRI增
2、强扫描,主要观察肿块的大小、形态、信号及其与周围组织结构的关系,并与病理结果对照。结果36例睾丸肿瘤中,无意中发现睾丸肿块12例,伴有酸胀沉重或下坠感24例;隐睾病史4例,斜疝3例。36例睾丸肿瘤中,精原细胞瘤13例,T2WI呈均匀低信号6例,结节状低信号1例,以低信号为主的混杂信号6例,其中含有低信号纤维间隔8例;浆细胞肿瘤2例(3个病变睾丸),肿块信号均匀,强化显著;胚胎癌7例,均呈混杂不均匀信号,肿块均较大,6例有远处转移,1例合并恶性畸胎瘤,患者发病年龄均<32岁;恶性淋巴瘤8例,T2WI呈均匀低信号3例,呈混杂信号5例,
3、附睾精索侵犯5例,其中6例患者发病年龄>62岁;Leydig细胞瘤6例,T2WI呈均匀低信号3例,呈混杂信号3例,鞘膜积液4例。结论MRI的多方位、多序列扫描技术有助于睾丸肿瘤及其周围组织结构的清晰显示,结合患者发病年龄及临床资料,MRI可对大多数不同病理类型的睾丸肿瘤作出鉴别诊断。关键词:睾丸;肿瘤;磁共振成像DOI:10.3969/j.issn.1002-1671.2013.11.023中图分类号:R737.21;R445.2文献标志码:A文章编号:1002-1671(2013)11-1807-05MRIandclinicfe
