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 value of computed tomography (CT) in diagnosing penile carcionma. Materials and Methods CT imaging and clinical information of 12 patients with penile carcinoma confirmed by pathology were retrospective reviewed. Results The CT findings included irregular lobulated soft tissue mass in glans penis with even density. The size of tumor ranged from 1 to 9 cm in greatest diameter, with a mean of 3.5 cm. After the injection of contrast medium, the tumors showed moderate enhancement and the depth of tumor invasion showed more clearly. Corpus cavernosum were involved in 7 cases, skin on the root of the penis was involved in 1 case. 8 cases have lymphoid node metastasis, among of them, 5 cases bilateral and 3 cases unilateral metastasis (2 cases fight, 1 case left). There have no pelvic lymph nodes and other organs metastasis in all the patients. Conclusion CT imagings show the size,shape of primary penile carcinoma and the depth of penis involvement. At the same time, CT can find out the lymphoid node metastasis and distant metastasis, provide a valuable reference information for the development of clinical treatment programs.
