目的探讨彩色多普勒超声对睾丸旁肿瘤的诊断与鉴别诊断价值。方法回顾性分析睾丸旁肿瘤47例(共78个结节)的彩色多普勒超声表现,结合术后病理对照分析其声像图特点。结果睾丸旁良性肿瘤33例(共62个结节),结节内部结构多为实性(55/62),多呈低回声(52/62),均匀回声44个,结节边界清晰58个,形态规则60个,0~Ⅰ级血流信号43个。恶性肿瘤14例(共16个结节),结节表现为受累部位弥漫性浸润(6/16)或局灶性病变(10/16),内部结构均呈实性,内部回声多呈不均匀的低回声(81.25%),边界不清10个,形态不规则11个,Ⅲ级血流信号12个。睾丸旁良、恶性肿瘤在肿瘤的回声均匀性、形态、边界及血供等征象的差异比较均有统计学意义(P<0.05),而两者内部结构、回声水平差异比较无统计学意义(P>0.05)。结论彩色多普勒超声对睾丸旁肿瘤具有一定的诊断与鉴别诊断价值,综合患者的病史、临床表现及其他临床检查资料有助于降低误诊率。
Objective To explore the value of color Doppler ultrasound in the diagnosis and differential diagnosis of parathyroid tumor. Methods Retrospective analysis of 47 cases of parathyroid tumor (a total of 78 nodules) color Doppler ultrasound performance, combined with postoperative pathological contrast analysis of its sonographic features. Results There were 33 benign benign tumors (62 nodules in total), the internal structures of nodules were mostly solid (55/62), mostly hypoechoic (52/62), uniform echoes 44, nodules clearly 58 , 60 morphological rules, 0 ~ Ⅰ grade blood flow signal 43. Malignant tumors in 14 cases (16 nodules), nodules showed diffuse infiltration of affected sites (6/16) or focal lesions (10/16), the internal structure was solid, the internal echo mostly uneven Of low echo (81.25%), unclear border 10, 11 irregular shape, grade Ⅲ blood flow signal 12. There was a significant difference in the signs of echogenicity, morphology, border and blood supply between benign and malignant tumors in the testis (P <0.05), but there was no significant difference in the internal structure and echo between the two groups P> 0.05). Conclusions Color Doppler ultrasound has some diagnostic and differential diagnostic value on parathyroid tumor. Combining the patient’s medical history, clinical manifestations and other clinical examination data can help to reduce the misdiagnosis rate.
