睾丸旁肿块彩色多普勒超声表现

目的总结睾丸旁肿块彩色多普勒超声表现。 方法回顾性分析2000年3月至2015年5月福建医科大学附属协和医院收治并经手术病理证实的133例睾丸旁肿块患者彩色多普勒超声表现。 结果133例睾丸旁肿块可分为4类：睾丸旁囊肿性病变48例，睾丸旁肿瘤50例（良性36例，恶性14例），睾丸旁炎性病变27例及睾丸旁瘤样病变8例。（1）囊肿性病变：44例呈类圆形囊性团块，2例呈类实性，2例呈囊实性，均边界清楚，无或少量血流信号；（2）良性肿瘤：35例肿块形态规则、境界清楚，1例形态不规则、境界不清，27例内部回声较均匀，33例无或仅有少量血流信号；恶性肿瘤：均表现为形态不规则、境界不清肿块，或睾丸鞘膜不规则增厚及附壁结节形成，内部回声紊乱，12例血流信号丰富，2例仅见少量血流信号；（3）炎性病变：24例肿块形态欠规则、境界不清，3例形态规则、境界清楚，少量或丰富血流信号；（4）瘤样病变：7例肿块形态规则、境界清楚，1例形态欠规则、境界欠清，内部回声多样，无或少量血流信号。 结论4类睾丸旁肿块各有其相应的彩色多普勒超声表现，部分睾丸旁肿块具有特征性彩色多普勒超声表现。彩色多普勒超声检查对睾丸旁肿块有一定的诊断及鉴别诊断价值。

Ultrasonic appearances of paratesticular masses

ObjectiveTo summarize the color Doppler ultrasound features of paratesticular masses. MethodsOne hundred and thirty-four cases of paratesticular masses proved by pathology were analyzed with their features of color Doppler ultrasound in Fujian Medical University Union Hospital from March 2000 to May 2015. ResultsOne hundred and thirty-three cases of paratesticular masses were divided into 4 categories, included 48 cases of cystic masses, 50 cases of tumors (36 cases of benign tumors and 14 cases of malignant tumors), 27 cases of inflammatory lesions and 8 cases of tumor-like lesions. Forty-four cases of cystic lesions were presented as round cystic masses while 2 cases were presented as solid-liked masses, 2 cases were presented as solid cystic masses. All of them had obscure boundary and no or little blood flow signal. Thirty cases of benign tumors were shown as well-defined, regular margined lesions while 1 case had irregular shape and obscure boundary. Twenty-seven cases were homogeneous and 33 cases had no or little blood flow signals. Malignant tumors were all appeared as poorly defined lesions with heterogenous echogenicity, or perididymises were irregular thickened with mural nodules. Twelve cases had rich blood flow signals while 2 cases had little blood flow signals. Twenty-four cases of inflammatory lesions had irregular shapes and obscure boundaries while 3 cases were shown as well-defined and regular marginrd. They had poor/rich blood flow signal. Seven cases of tumor-like lesions had regular shapes and clear boundaries while 1 case had irregular shape and obscure boundary. They had various echogenicity, no or little blood flow signal. ConclusionsThe 4 types of paratesticular masses had certain sonographic features. Some of the masses have characteristic sonographic appearance. Color Doppler ultrasound has certain value in diagnosis and differential diagnosis of paratesticular masses.
