The Significance of Ultrasonic Diagnosis in Pediatric Yolk Sac Tumor:a Comprehensive Analysis with Insights into Cases of Missed and Misdiagnosis
Objective To investigate ultrasonographic features and diagnostic value of pediatric yolk sac tumor(YST),and to improve the accuracy of preoperative ultrasonographic diagnosis of YST.Methods A retrospective analysis was conducted on clinical manifestations,laboratory test results,and ultrasonographic features of 29 children with YST confirmed by pathology,and the reasons for missed diagnosis and misdiagnosis were summarized.Results Among the 29 pediatric patients,25 cases were correctly diagnosed by ultrasonography,1 case was missed,and 3 cases were misdiagnosed,with a compliance rate of 86.21%.The serum alpha-fetoprotein(AFP)levels of all children were significantly elevated at the time of initial consultation,all greater than 1000 ng·mL-1.Conclusion Ultrasonography has an important clinical application value in the diagnosis of YST in children.The combination of significantly elevated AFP levels can improve the accuracy of preoperative ultrasonographic diagnosis,which is helpful for early diagnosis and confirmation of YST.
