摘　　要：目的:探讨隐睾合并精原细胞瘤的CT特点,以期提高对本病的认识。方法:对7例经手术病理证实的隐睾合并精原细胞瘤的CT图像进行回顾性分析。结果:7例隐睾合并精原细胞瘤中,2例位于后腹膜,3例位于盆腔腹膜外,2例位于腹股沟管。其CT征象有肿块以实质性为主;肿块可有完整包膜,如边缘不清则提示有局部侵犯;肿块长轴多与睾丸下行路径一致;腹股沟管内口附近肿块可见伪足状突起。结论:隐睾合并精原细胞瘤的CT征象有相对特征性,对于本病的诊断具有重要价值。Objective：To study the CT features of cryptorchidism complicated with seminoma. Methods：CT findings of 7 patients with pathologically proved cryptorchidismcomplicated with seminoma were collected and retrospectively studied. Results：In the 7 cases of cryptorchidism complicated with seminoma,tumors were found in retroperitoneal space （n= 2）, pelvis （n= 3） and inguinal canal （n= 2） respectively. Typical manifestations of the s eminomas on CT scans were as follows. Tumor masses were primarily solid,these malignant masses might have had intact capsules and in Case that ill-defined margins were demonstrated, involvement of surroundings Was indicated; the long axis of the masses was always consistent with the regular descending course of embryonic testes;masses with pseudopod-like protrusions might be found in the ones around the deep inguinal ring. Conclusion.. There weresome considerably specific CT signs in the cases of cryptorchidism complicated with seminoma,therefore,CT examihation was an effective imaging modality for diagnosing patients with this disease.
