Abstract:
Objective To investigate sonographic characteristics of struma ovarii with conventional ultrasound and CEUS.Methods Ultrasound images of 65 patients with struma ovarii confirmed by pathology were retrospectively reviewed and analyzed,5 patients were examined with CEUS simultaneously.Results In all 65 patients,lesions in 14 (14/65,21.54 ％) were multocular,49 (49/65,75.34％) were cystic-solid component,2 (2/65,3.08％) were solid.Lesions in 39 (39/65,60.00％) contained dense latticed separation.The abundant blood flow was found in 18 cases (18/65,27.69％) with Doppler examination.Five cases were examined with CEUS,including multilocular lesions of 2 cases and cystic-solid lesions of 3 cases.Regular middle-degree intensity of cyst wall and septa were seen in all 5 cases.Among cystic-solid lesions of 3 cases,lesions of non-enhance pattern was seen in the solid areas of 1 case,irregular middle-high degree intensity pattern were seen in the solid areas of 2 cases,while non-enhance pattern could be seen in part of the solid areas of these 2 cases.All the cystic areas of these 5 cases showed non-enhance pattern.Conclusion The sonographic appearances of struma ovarii are usually multilocular or multilocular with solid component.Because of strum ovarii's special characteristic pathologic components,the imaging features of strum ovarii in conventional ultrasound and CEUS are atypical,thus preoperative diagnosis is quite difficult.
