Abstract:
Objective To study the CT findings of struma ovarii(SO)and improve the understanding of SO imaging features. Methods CT images of 6 cases were retrospectively reviewed.CT plain scan was performed in 6 patients;CT enhancement scan was performed in 2 patients.Results All tumors were unilateral.On non-enhanced CT,the lesions presented as well-defined irregu-lar cystic-solid masses.The cystic portions presented as well-defined,multiple,various size,and there were entire cystic walls with smooth inner wall.Four tumors showed high attenuation lesions in the cyst portion of the mass on precontrast scans.The solid por-tions showed irregular tissue density,and were often distributed in the cysts.The tumors showed stippled calcification in solid por-tions and/or cystic wall in 4 cases.One tumor accompanied a great of ascites liquid.After contrast administration,the cystic por-tions showed no enhancement,and the cystic walls and the solid portions showed mild enhancement.Conclusion CT findings of SO have certain characteristics such as a cystic-solid and well-defined mass with calcification,high attenuation lesion on plain CT,and marked solid part enhancement on contrast CT.
