Abstract:
Objective To evaluate computed tomographic findings of struma ovarii so as to improve the knowledge of the imaging diagnostics of this disease.Methods Computed tomography (CT)scans and clinical data of 12 pathologically proven struma ovarii were reviewed retrospectively.Scans were evaluated for the laterality,size,margins,configuration,internal architecture,presence of intracystic high attenuation lesions on pre-contrast scans,the presence of calcifications,solid components enhancement,cyst wall enhancement,and ascites.Results All tumors were unilateral and had smooth margins.Cystic (n = 3)or mainly cystic (n = 9) appearance was common to all the tumors.Eight tumors showed a high attenuation lesion in the cyst portion of the mass on pre-con-trast scans.Calcification was found in 5 cases.The solid components showed different degrees of enhancement after administration of contrast medium.The cyst wall showed mild to moderate enhancement after administration of contrast medium.Five cases of tumors accompany a small amount of ascites.On pathology,the solid portions of the tumor consisted of the thyroid tissue and stoma which contained abundant blood vessels and fibrous tissue,and the cystic portions were filled with high gelatinous fluid of eosinophil-ic colloid.Conclusion On CT scans,struma ovarii appeared most often as a smooth marginated multicystic mass with a high attenu-ation lesion and calcification on pre-contrast scans with marked enhancement of the solid components.
