Abstract:
Objective:To explore the clinical and imaging features of the concomitant gastric-type endocervical adenocarcinoma(G-EAC)in female patients with Peutz-Jeghers syndrome(PJS),so as to improve the early diagnostic level for PJS.Methods:A retrospective analysis was performed on the clinical and imaging data of 12 patients who were confirmed as PJS with G-EAC at Air Force Medical Center,PLA from June 2021 to December 2024.The 12 patients all received computed tomography(CT)examination before surgery,and 6 cases among of them received magnetic resonance imaging(MRI)examination at the same time.The features of clinical performance,and imaging features of CT and MR in all patients were analyzed.Results:In 12 G-EAC patients,7 cases(58.3%)did not occurred any abnormally relative symptoms of gynaecology and obstetrics,while 5 cases(41.7%)occurred increase of vaginal drainage and/or vaginal bleeding.The results of imaging examination indicated that 12 cases occurred concomitant cyst,including 5 cases(41.7%)with large cysts,6 cases(50.0%)that micro cysts coexisted with large cysts,1 case(8.3%)that solid mass combined with small amount of micro cysts,and 4 cases(33.3%)that combined with small amount of uterine cavity effusion.MR performance was the most of occurrences were quasi-circular object with long T1/T2 signals,and the sequences of diffusion weighted imaging(DWI)appeared there was no diffusion or mild restriction,and apparent diffusion coefficient(ADC)appeared slightly high signal.The tumors that mainly were solid components appeared longer T2 signals,which diffusion was limited,and which ADC values appeared low signals.CT images of them presented enlarged cervixes,and mixed-density cystic and solid nodules and mass shadows at local tissues,and cellular change at local lesions.There was not significant strengthen at the cystic fields of the lesion with enhanced scan,and the solid fields appeared uneven enhancement.The accuracy rates both of preoperative CT and MR diagnosis were 50.0%.Conclusion:The clinical appearance,and imaging futures of CT and MR examinations of PJS female patients with G-EAC are respectively:partial patients occur vaginal drainage and/or vaginal bleeding,the most of tumors often occurs at the entire cervix(includes upper segment),often combines with cystic changes,and often appears infiltrating growth.The clinical PJS appearance,CT and MR examinations contribute to early diagnosis for G-EAC.
