摘要 目的总结儿童纵隔常见肿瘤的超声图像特点。方法回顾性分析怀疑纵隔肿瘤的病例。以病理结果作为金标准。总结各类纵隔肿瘤的超声图像特点。结果共纳入患儿145例,男76例,女69例,年龄(7.12±4.04)岁。位于后纵隔的占位51个,表现为实性低回声基础上沙粒样细小钙化;弥漫性累及上纵隔胸腺76个,表现为实性低回声;局限于上纵隔胸腺内部者7例,表现为实性低回声基础上散在无回声区;位于上纵隔胸腺外者3个,均为实性,内部低回声1个,中等回声者2个。瘤体巨大占据胸腔者6个,表现为实性低回声基础上出现无回声区。所有肿瘤中实性区域可探及血流信号。结论儿童纵隔肿瘤发生的位置及部分瘤体内部回声存在特异度。彩色多普勒超声检查可作为儿童纵隔肿瘤首选的筛查方法。 Objective To summarize the ultrasonic features of tumors in mediastinum in children. Methods The patients with suspected mediastinal tumors were analyzed retrospectively. The pathological results were taken as the gold standards. The ultrasonic image characteristics of all kinds of mediastinal tumors were summarized. Results A total of 145 children, 76 males and 69 females, aged(7.12 ±4.04) years, were included. There were 51 lesions were located in posterior mediastinum space, the ultrasound features showed micro-calcification on solid hypoechoic. There were 76 cases of diffuse involvement of thymus, ultrasound showed solid hypoechoic with enlarged peripheral abnormal lymph nodes. 7 Cases with tumor focal within thymus, ultrasound images show solid hypoechoic dispersion in liquefaction zone. Three patients with tumours in the superior mediastinal outside thymus. All of tumors were solid, 1 with hypoechoic, 2 with iso-echo. 6 cases with massive tumor occupied mediastinum, ultrasound showed liquefaction area on the basis of solid hypoechoic. Blood flow signals can be detected in solid regions of all tumors. Conclusions The location of mediastinal tumor in children and the echo in some tumors are specific. Color Doppler ultrasound examination can be used as the first screening method for tumors of mediastinum in children.
