目的 分析睾丸非肿瘤性病变的超声与CT诊断价值。方法 回顾性分析58例经临床病史、超声、CT或病理证实的睾丸非肿瘤性病例,结合临床病史,分析其超声与CT表现,包括炎性(或感染性)病变、外伤性病变、先天性病变及扭转急症。结果 所有病例均行CT检查,睾丸炎症性病变共39例(包括一般性炎症,脓肿和结核),其中19例行超声检查;睾丸外伤8例,隐睾9例,睾丸扭转2例,均行超声检查。睾丸炎症性病变临床表现为患侧或双侧阴囊不同程度的红、肿、痛,或白细胞升高、其他脏器伴发结核,超声表现为睾丸体积不同程度增大,根据炎症坏死程度不同,回声表现为回声均质、回声减低、回声不均质,坏死灶内无血流信号;CT表现为睾丸体积增大,根据炎症性病变的不同可表现为睾丸轻度强化、环形强化,可伴有睾丸鞘膜积液、点状钙化或积气;睾丸外伤均有阴囊外伤史,根据受伤程度表现为白膜下血肿、实质出血、睾丸破裂;隐睾表现为睾丸位置异常或缺如;睾丸扭转表现为睾丸短时间内剧烈疼痛,并进行性加重,超声表现为“镯环征”,CT表现为精索扭转、水肿,睾丸实质水肿。结论 睾丸非肿瘤性病变超声与CT征象均具有特征性,结合患者病史可作出准确诊断。超声检查较为便捷,CT检查可免除受检者接触性疼痛、可对盆腔及腹腔进行更为全面的观察。

Objective: Discussion on diagnosis of testicular non-tumorous lesions by ultrasound and CT.Methods: Rretrospective analysis of 58 testicular non-tumor cases proved by clinical history, Ultrasound, CT or pathologically,combined with the clinical history, and analysis of the Ultrasound and CT features,including inflammatory or infectious disease, traumatic disease, congenital disease and acute torsion.Results: All cases were examined by CT,the testicular inflammatory lesions were 39 cases, 19 of them were examined by ultrasound; testicular trauma 8 cases,cryptorchidism 9 cases, testicular torsion in 2 cases, all of them were examined by ultrasound. The clinical symptom of the inflammatory lesions of the ipsilateral or bilateral scrotum with different degrees of red, swollen, painful, or leukocytosis, other organs associated with TB, Ultrasound showed the testicular volume increased to varying degrees,according to the degree of inflammation and necrosis, the echo showed homogeneous echo, echo reduction, echo heterogeneity, and no blood flow signal in the necrotic area.CT showed an increase in testicular volume, according to the different inflammatory lesions showed mild enhancement of testis, ring enhancement, with a hydrocele, calcification or gas; testicular trauma had scrotal trauma history, according to the severity of injury showed subcapsular hematoma, hemorrhage and rupture of testis; testicular cryptorchidism showed abnormal position or absent; testicular torsion showed testicular short time severe pain, and progressive, Ultrasound showed “bracelet ring sign”, CT showed testicular torsion, edema, testicular parenchyma edema.Conclusion: Ultrasound and CT features of testicular non-tumorous lesions are characteristic, and the accurate diagnosis can be made with the combination of the patient's clinical history. Ultrasound examination is more convenient, CT examination can relieve the patient's contact pain, can be more comprehensive observation of the pelvic and abdominal.
