Abstract:
Objective To explore the imaging characteristics of ovarian fibroma on CT and MRI.Methods The CT and MRI findings of 12 patients with ovarian fibroma proved by surgery and pathology,including 12 cases of CT scan and 5 cases of MRI scan,were retrospectively analyzed.Results All of 12 patients with ovarian fibroma showed solitary masses with well defined margin and roughly round or mildly lobulated shape.On CT plain imaging,3 ovarian fibromas were homogeneous or roughly homogeneous solid masses,8 mixed masses with cystic and solid parts,and 2 mainly cystic masses.5 masses with MRI showed isointensity or mildly hypointensity on T1WI and significantly inhomogeneous intensity on T2WI with stripy and flaky hypointensity in solid parts.The solid parts of mass were enhanced slightly and gradually after intravenous administration of contrast material,and 4 masses showed complete envelopes on enhanced MRI.10 cases showed little of ascites concomitantly.Conclusion The CT and MRI findings of ovarian fibroma are characteristic to some extent.Masses with well defined margin and roughly round or mildly lobulated shape,slight and gradual enhancement,hypointensity of solid part on T2WI and complete envelope showed on MRI,suggest the possible diagnosis of ovarian fibroma.
