目的探讨螺旋CT对腹内未降睾丸巨大纯精原细胞瘤的诊断价值.方法回顾性分析经手术病理证实的6例巨大的腹内未降睾丸纯精原细胞瘤的螺旋CT表现.结果 6例肿块长轴与同侧肾下极和腹股沟内环的连线一致.供血动脉均为同侧睾丸动脉,5例显示睾丸静脉引流.同侧睾丸及精索未显示,2例肿块尾端见未退化的睾丸引带.同侧肾脏受压上移.肿块呈囊实混合型,内侧坏死明显,其内可见条状纤维血管分隔,实性部分轻度均匀强化.所有肿块内未见钙化或脂肪.结论螺旋CT是腹内巨大精原细胞瘤术前定位定性诊断的一种有用的影像手段.

Objective To assess the diagnostic capability of spiral CT for giant pure seminoma in intraabdominal undescended testis.Methods Spiral CT of 6 cases with pure seminoma of inabdominal testes as proved by surgery and pathology were analyzed.All patients were male,and the age ranged from 31 to 45 years old with the mean of 35.2 years old.Results All tumors were located along the path of testicular descent on CT images.The arterial-supply of tumors all came from the testicular artery ipsilaterally.The draining vein could be seen between the mass and inferior vena cava or left renal vein in 5 cases.Isolaterally spermatic cord was absent in the inguinal region.Isolateral kidney was shifted upward.CT scans typically demonstrated a unilateral,mixed solid and cystic mass,with areas of solid located at the lateral aspect and areas of necrosis at the medial aspect.Contrast-enhanced CT scan showed mild enhancement of solid areas and band-like septal enhancement in areas of necrosis.There is no evidence of calcification or fat within the mass.Conclusion Spiral CT proves to be a very useful preoperative imaging modality for the giant intraabdominal seminoma.
