ABSTRACT

Objective To analyze CT findings of misdiagnosed or missed ovarian cystic mature teratomas to improve the diagnosis.Methods CT images of 145 cases were retrospectively reviewed.Among them,29 cases of ovarian cystic teratomas were misdiagnosed or missed.Results Five cases of struma ovarii were diagnosed as cyctadenocarcinoma,7 cases of cystic mature teratoma were misdiagnosed as cyst in 2 cases,ovarian endometrial cyst in 2 cases and cystadenoma in 3 cases.17 cases of cystic mature teratoma weremissed diagnosis, in which there were torsion in 7 cases,infection in 4 cases,bleeding in 3 cases,endometriosis cyst,serous cystadenoma and tuberculosis in 1 case respectively.Conclusion Understanding the atypical misdiagnosed or missed CT manifestation of ovarian cystic mature teratomas permits a more specific and accurate diagnosis,which may be useful for preoperative diagnosis.
