Abstract:
Objective To analyzed the CT features of struma ovarii(SO).Methods The clinical data and CT features of eleven patients with pathologically proved SO were retrospectively analyzed.CT features were compared with pathological results.Results(1)All tumors were unilateral.On non-enhanced CT,the lesions presented as well-defined irregular masses,which were cystic-solid(n=6,54.5%)or cystic(n=5,45,5%).(2)The cystic portions presented as well-defined,multiple,various size,and there were entire cystic walls with smooth inner wall.The tumors(63.6%)showed a high at attenuation lesions in the cyst portion of the mass on precontrast scans and the attenuation ranged from 72.3 to 113.5 Hounsfield units(HU)in 7 cases.The solid portions showed irregular tissue density,and were often distributed in the cysts.After contrast administration,the cystic portions showed no enhancement,the solid portions marked enhancement,and the cystic walls demonstrated no moderate,or marked enhancement.(3)The tumors(72.7%)showed stippled calcification in solid portions and(or)cystic wall in 8 cases.(4)The tumors(27.3%)accompanied with mature cystic teratomas,and showed fat density in 3 cases.(5)The tumors(27.3%)accompanied a great of ascites and pleural liquid.Conclusion CT characteristics of SO might be of great value for the diagnosis.
