Exploration of Ultrasound Misdiagnosis of 9 Cases of Follicular Membrane Fibroma
Objective:To investigate the ultrasonographic features and causes of misdiagnosis of follicular membrane fibroma,and to improve the accuracy of ultrasonographic diagnosis.Methods:Clinical data of patients with surgical pathologically confirmed follicular membrane fibroma in the hospital from January 1,2014 to October 30,2022 were collected,and the clinical and ultrasonographic data of nine of these patients with ultrasound misdiagnosis were selected for analysis.Results:Of the 9 patients,3 patients were misdiagnosed with uterine subplasma leiomyoma(33.3%),and 6 with ovarian cancer(66.7%).6 out of 9 patients showed mixed cystic-solid echogenic masses,with solidity accounting for 80%～97%of the cases,4 cases showed slightly enhanced echoes posteriorly,and 1 case was accompanied by attenuated echoes posteriorly.3 cases showed solid masses,and among the solid masses,1 had homogeneous echogenicity and 1 had inhomogeneous echogenicity,and in 8 cases,0.40<resistance to blood flow index<0.5(88.9%).Conclusion:The sonogram of follicular membrane fibroma is dominated by solid and predominantly solid cystic masses with certain characteristics,but lacks specificity and is easy to misdiagnose.And its site of onset,internal echogenicity,borders and other features is conductive to ultrasound diagnosis and differentiation.
