腹部隐睾精原细胞瘤的CT诊断

CT diagnosis of abdomen enorchia seminoma

目的:探讨腹部隐睾精原细胞瘤的CT特点,以提高对本病在腹部肿瘤中的诊断。方法:总结分析经手术病理证实的7例精原细胞瘤,对其影像表现进行回顾性分析。结果:4例表现为单侧腹部肿块,内见不规则小片状低密度坏死灶,肿块长轴与睾丸下行路径一致,3例较大肿块跨越脊柱前方位于腹膜后。结论:隐睾精原细胞瘤的CT征象具有相对的特征性,密切结合临床综合分析,对于本病的诊断有重要价值。

Objective： To study the CT features of abdomen enorchia seminoma,to improve the CT diagnosis of abdomen enorchia seminoma.Methods： CT findings of 7 patients with pathologically proved testicular seminoma were collected and retrospectively studied.Results： 4 cases of the 7 patients were found the hemi-tumor,and Intratumorous necrosisor cystic changes were found,the long axis of the tumors was always consistent with the regular descending course of embryonic testes.3 cases of biggish tumors were found in retroperitoneal space.Conclusion： There are some considerably specific CT signs in the cases of enorchia seminoma,closely combined with clinical symptoms,CT examination is an effective imagingmodality for diagnosing patientswith this disease.
