目的探讨阴茎癌的CT表现及其诊断价值。资料与方法回顾性分析12例经手术病理证实的阴茎癌患者的CT表现。结果CT表现为阴茎头不规则分叶状或菜花状软组织肿块,密度均匀,肿瘤直径1～9 cm不等,平均3.5 cm。增强扫描动脉期病变呈中度强化,此期显示肿瘤侵犯深度更加清楚,7例显示阴茎海绵体受累,1例阴茎根部皮肤受累。8例淋巴结转移,其中双侧转移5例,单侧转移3例(右侧2例,左侧1例)。12例患者中均未发现盆腔淋巴结及其他脏器转移。结论CT可显示阴茎癌原发肿瘤的大小、形态及对阴茎侵犯深度,同时可显示淋巴结及远处转移情况,为临床制定治疗方案提供参考。
Objective To investigate the CT findings and the diagnostic value of penile cancer. Materials and Methods Retrospective analysis of CT findings of 12 cases of penile cancer confirmed by surgery and pathology. Results CT showed irregular lobulated or cauliflower soft tissue mass with uniform density and diameter of 1 ~ 9 cm with an average of 3.5 cm. Enhanced scanning artery lesions were moderately enhanced, this period showed that the depth of tumor invasion more clearly, 7 cases showed penile cavernous involvement, 1 case of penile root skin involvement. 8 cases of lymph node metastasis, including bilateral metastasis in 5 cases, unilateral metastasis in 3 cases (right in 2 cases, left in 1 case). None of the 12 patients had pelvic lymph nodes and other organs metastasized. Conclusion CT can show the size and shape of the primary tumor of penile cancer and the depth of the penis invaded, and can also show the status of lymph nodes and distant metastases, and provide a reference for the clinical treatment plan.
