The Value Of Ultrasonography In Mediastinal Tumors In Children

Objective : To explore the ultrasonic image characteristics and diagnostic value of mediastinal tumors in children.Method: The ultrasonographic manifestations and clinical data of 57 cases of mediastinal tumors in children confirmed by operation and pathology were reviewed,Analysis of the characteristics of the sonogram and the value of ultrasound diagnosis.Results : Among the 57 tumors,22 were neuroblastoma,14 lymphoma and primitive neuroectodermal tumor There were 5 cases of tumor,PNET),3 cases of teratoma,2 cases of ganglioneuroma,2 cases of angioma and 2 cases of lipoblastoma,1 case of thymoma,1 case of thymoma,1 case of liposarcoma,1 case of Langerhans cell histiocytosis,1 case of germ cell tumor,1 case of fibromyxoid sarcoma and 1 case of extrarenal malignant rhabdomyoid malignant schwannoma;21 cases of tumors in the anterior mediastinum and 1 case of tumors in the middle mediastinum Three tumors occurred in the anterior mediastinum and 32 in the posterior mediastinum.Ultrasound guided puncture was performed in 27 cases,and ultrasound diagnosis was consistent with pathological diagnosis in 27 cases.Among them,the most common tumor in the posterior mediastinum is neuroblastoma,with medium mixed echo,strong echo calcareous component,and abundant blood supply;the most common tumor in the anterior mediastinum is lymphoma,with medium and low echo as the main,mixed echo and nodular sense,and abundant blood supply.Conclusion: Ultrasound can determine the location of mediastinal tumor,and it has the advantage of real-time guided biopsy.It can be used as the first choice of imaging examination method and the main monitoring method of follow-up.
