腹腔内隐睾恶变的CT诊断

CT diagnosis of canceration of intra-abdominal cryptorchidism

目的:探讨腹腔内隐睾恶变的CT影像特征,以提高对本病的认识。方法:对22例经手术病理证实的腹腔内隐睾恶变的临床及CT影像资料进行回顾性分析。结果:22例腹腔内隐睾恶变患者中,其CT征象均为实质性软组织肿块,直径大小均超过2.0cm,20例形态为类椭圆形或类圆形,17例肿块有完整包膜,5例包膜边缘部分不清提示有局部侵犯,22例均伴低密度坏死灶(18例呈偏心性),15例可见条索状明显强化间隔影。结论:腹内隐睾恶变CT征象有相对特征性,对于本病的诊断具有重要价值,如果有隐睾史,CT上表现为腹腔内类椭圆形或类圆形软组织肿块,直径大于2.0cm,内伴偏心性坏死灶及条索状间隔者,应高度怀疑为隐睾恶变。

Objective：To explore the CT imaging characteristics of canceration of intra-abdominal cryptorchidism to improve the understanding.Methods：The clinical data and CT findings of 22 cases of canceration of intra-abdominal cryptorchidism proved by pathology results were retrospectively analyzed.Results：In 22 cases,all were solid soft tissue mass in CT signs,and the mass lengths were more than 2.0 cm.20 cases were elliptic or round,17 cases had intact capsules and 5 cases had unclear capsular edge,which indicating local invasion,22 cases were accompanied with low density necrosis（18 cases were eccentric）,15 cases had strip interval with ob-vious enhancement by post-contrast CT scanning.Conclusion：CT examination has relative characteristic in canceration of intra-abdominal cryptorchidism,and has important value to diagnosis.If abdominal CT of a male patient with cryptorchidism shows elliptic or round solid soft tissue mass,and the mass length is more than 2.0 cm with eccentric necrosis and strip interval,canceration of cryptorchidism should be highly suspected.
