Abstract:
Objective To explore the value of MRI in differentiation diagnosis of benign ovarian mucin-ous cystadenoma ( MC) and borderline mucous cystadenoma ( BMC).Methods MRI data of 23 cases of benign MC and 14 cases of BMC, confirmed by surgery and pathology, were retrospectively analyzed, including tumor lo-cation, shape, size, loculation, signal intensity of cyst fluid, cyst wall, cyst septum and nodules, and they were compared with pathological results.Results Single loculus benign cystadenoma nodules showed isointensity T2 WI signal, low T1 WI signal, and low DWI signal.Single loculus borderline cystadenoma nodules showed high T2 WI signal, low T1 WI signal, and high DWI signal.Signs such as honeycomb loculi of multilocular cystadeno-ma, cyst fluid of high T1 WI signal, cyst fluid of low T2 W1 signal, cyst wall and irregularly thickened cyst septum ( >3 mm) were more seen in BMC (7/11, 6/11 and 7/11) than in MC (5/18, 4/18 and 5/18);5 cases were with cyst sediments (MC=4, BMC=1), showing moderate T2WI signals, and high T1WI signals.Broken fish-ing net gathering was only restricted to MC (5/18) with characteristics.Benign multilocular cystadenoma nodules showed low DWI signal,and borderline multilocular cystadenoma nodules showed high DWI signal.Conclusion MRI can well display pathological characteristics of ovarian MC, which has practical value for the differentiation and diagnosis of MC and BMC and can provide the reference for clinical surgery.
