不可触及隐睾及其恶变的MSCT诊断价值

目的 探讨MSCT对腹部隐睾及其恶变的诊断价值.方法 回顾性分析经手术病理证实的29例33枚临床未触及的隐睾及其CT表现,其中3枚恶变.结果 29例33枚隐睾全部检出并定位,其中4例为双侧隐睾,5枚均位于腹腔内,1枚位于髂窝部腹膜后,2枚位于腹股沟区.25例单侧隐睾中17枚位于腹腔内,3枚位于腹膜后,5例位于腹股沟区.其CT征象为卵圆形或类圆形软组织肿块,肿块长轴多与睾丸下降路径一致.无恶变者边界清楚,轮廓光整,较正常睾丸小,密度均匀.若肿块较大、密度不均匀、形态不规则,并由患侧睾丸动脉供血者,则可作出腹部隐睾恶变的定性诊断.结论 MSCT能检出不可触及的隐睾,并鉴别是否恶变,对术前定位定性、指导临床手术具有较高的价值.

Do not touch the cryptorchidism and its value of MSCT in the diagnosis of malignant transformation

Objective To evaluate the value of MSCT in diagnosis of abdominal cryptorchidism and evil change. Methods Aretrospective analysis of 29 cases confirmed by surgery pathology 33 clinical cryptorchidism and CT mani- festation of untouched, of which 3 malignant. Results The 29 cases of cryptorchidism in detection and localization for all 33 medals, including 4 cases of bilateral cryptorchidism, 5 of which were located in the abdominal cavity, 1 was located in the iliac fossa retroperitoneal, 2 cases were located in the inguinal region. 25 cases of unilateral cryptorchidism 11 in 17 were located in the abdominal cavity, 3 cases were located in the retroperitoneum, 5 case in the inguinal region. The CT signs were oval or round soft tissue mass, mass reduction and testis axis multi path. No malignant change of clear boundary, contour, compared with normal testicular small, uniform density. If large masses, uneven density, irreg- ular shape, and by the ipsilateral testicular artery, qualitative diagnosis made abdomen enorchia canceration. Conclu- sion MSCT can check out the untouchable cryptorchidism, and identify whether evil change, the preoperative localiza- tion qualitative and guide clinical surgery is of high value.
