腹部隐睾精原细胞瘤的CT诊断

摘要

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.%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.
