Ultrasonographic Features Of Cervical Lymph Node Lesions In Children And Teens

Objective: To compare the constituent ratio differences of cervical lymph node lesions between children/teens and adults and explore the ultrasonographic features of cervical lymph node lesions in children and teens. Methods: Retrospective analysis of the clinical,pathological and ultrasonic examination data of patients with neck lymph node enlargement diagnosed by ultrasound from January 2014 to December 2015, including1432 adult patients(≥18 years old) and 289 child/teen patients(<18 years old). Comparison of the constituent ratio of cervical lymph node lesions in adults and children/teens, to analyze the incidence of cervical lymph node lesions in adults and children/teens.Preliminary study on ultrasound imaging features of cervical lymph node lesions in children and teens. Results: There were statistically significant differences in the proportion of cervical lymph node lesions in children/teens and adults(P<0.05). In children/teens and adults, benign reactive hyperplasia was dominant in cervical lymph node lesions(children and teens 87.20%, adults 54.89%), The malignant lesions in children and teens group only accounted for a very small part(3.45%), The proportion of malignant lesions in adult group(31.64%) was significantly higher than that in children and teens.The study of children and teens cervical lymph node benign and malignant lesions of ultrasonographic manifestations are as follows: benign sonographic characteristics of L/S≥2(93.90%), the lymphatic porta is in the center of the lymph node(82.44%), the blood flow signal is lymphatic portal type(84.23%);malignant sonographic characteristics of L/S<2(60.00%), the lymphatic porta is in the center of the lymph node(60.00%),the blood flow signal is lymphatic portal type or mixed type. Conclusion: There were differences in the constituent ratio of cervical lymph node lesions in children/teens and adults. Ultrasonic examination as the preferred method for diagnosis of cervical lymph node lesions, has important diagnostic value in children and teens’ lesions.
