Abstract： Objective: To investigate the MRI and ultrasonic features of struma ovarii(SO) and to improve the diagnostic level. Methods: The MRI, ultrasound features and pathological findings of 9 cases of SO proved by operation and pathology were retrospectively analyzed. Results: All of the 9 cases were unilateral, 7 cases on the right and 2 cases on the left. On plain MRI, 3 cases were cystic and 6 cases were mixed cystic and solid, nodules were seen in 5 cases. The signals of mass were complex, high signals on T1WI were seen in 7 cases, extremely low signals were seen on T2WI in 7 cases. The ADC values of the high signal regions, low signal regions and extremely low signal regions were (2.576±0.130)×10-3 mm2/s, (1.641±0.349)×10-3 mm2/s, (0.763±0.373)×10-3 mm2/s. On enhanced MRI, the solid, wall and septum of the mass were obviously enhanced. The ultrosonic findings were mixed masses with poor acoustic transmission, dense and thick light-spots were found in 4 cases while strong-echo light-spots were found in 5 cases. Conclusion: There are certain characteristics in MRI and ultrosonic findings of SO. The MRI combined with ultrosonography might be of great value for diagnosis of SO.
