Abstract：Objective To explore the clinical and imaging features of gastric-type endocervical adenocarcinomas(G-EAC)in order to improve the level of early diagnosis.Methods The clinical and imaging data of 16 patients with pathologically confirmed G-EAC who were admitted to the Air Force Medical Center between January 2021 and February 2025 was retrospectively analyzed.Results Among the 16 patients,7 had no abnormal gynecological symptoms while 9 had vaginal discharge and/or vaginal bleeding.HPV test was positive in 3 cases and 10 cases had abnormal tumor markers.The tumors were located in the upper half of the cervix in 5 cases,involved the entire cervix in 8 cases,and extended beyond the cervix in 3 cases.Four cases showed barrel-shaped growth and 11 cases were infiltrative,while 1 case presented as exophytic mass.All the 16 cases were accompanied by cysts,including 5 cases with large cysts,9 cases with small cysts and large ones,and 2 cases with small cysts.Four cases were complicated with a small amount of uterine cavity effusion.When the cystic component was predominant,multiple rounded lesions of varying sizes with long T1 and long T2 signals were observed.There was no or slight restriction in diffusion on DWI sequence,and slightly high signals in ADC image.When the solid component was predominant,slightly long T2 signal soft tissue shadows were seen,with restricted diffusion and low signals on the ADC map.CT images presented with enlarged cervixes,with mixed-density cystic and solid nodules or masses,and some lesions showed"honeycomb-like"changes.Enhanced scanning showed no obvious enhancement in cystic areas or uneven enhancement in solid areas.The preoperative accuracy rate of CT/MRI diagnosis of malignant lesions was 68.7％.Conclusion Most patients have elevated tumor markers,and some have vaginal discharge/bleeding.Imaging features such as tumor prevalence in the whole cervix(including the upper part),complications with cyst-like changes,and infiltrative growth can facilitate the early diagnosis of gastric-type adenocarcinomas of the cervix.
