摘　　要：目的：研究腹盆生殖细胞瘤ＭＲＩ、ＣＴ表现。方法：本组８例经病理证实腹盆生殖细胞瘤，均为男性，年龄２１～４８岁，平均年龄３０．０岁。ＭＲＩ检查５例，ＣＴ检查３例。结果：肿瘤位于腹膜后４例，盆间隙４例。肿瘤直径８～２０ｃｍ，４例直径＜１０ｃｍ，４例直径＞１０ｃｍ。圆形、椭圆形３例，不规则状５例。位于腹膜后呈不规则状，内部见囊变及钙化，侵犯周围组织；位于盆内呈境界清之肿块，以推移周围器官改变为主。ＣＴ或ＭＲＩ不易鉴别原发或继发病变。结论：腹盆内生殖细胞瘤在腹膜后和盆间隙表现不同，原发或继发病变表现相似。Objective:To study the MRI and CT features of germinoma in abdomen and pelvis.Methods:Eight cases of germinomas proved by pathology were presented.All cases were men.The age ranged from 21～48 years,with an average age of 30.0 years.MRI studies were obtained in 5 cases,and CT in 3 caese.Results:4 cases were seen in retroperitoneal space,and 4 cases in pelvis space.Tumors were 8～20 cm in diameter,which less than 10 cm in diameter were in 4 cases,more than 10 cm in 4 cases.3 tumors were round or oval in shape,5 tumors were irregular shape.The retroperetoneal tumors appeared as irregular shape with cystic change,small calcification and invasion of adjacent tissues.The tumors in pelvis showed well difined masses,and displacement of the abjacent tissues and organs.We could hardly differentiate the primary tumor from the secondary one on CT or MRI.Conclusion:CT or MRI manifestations of retroperitoneal germinoma differ to that of pelvic one.But the findings of primary mass are as same as the secondary one.
