Abstract:
Objective To study the radiological appearance and pathological features of breast phyllodes tumors(PTs), and to enhance the knowledge of the tumor.Methods Clinical and imaging findings were reviewed retrospectively in 65 women with PTs confirmed by surgical pathology.61 patients had preoperative MRI and/or sonography, and 44 had preoperative mammography.Then these findings were compared with the pathological results.Results (1)The percentages of benign, borderline and malignant PTs were 32.3%(21/65), 43.1%(28/65) and 24.6%(16/65), respectively,and the mean maximum diameters of these lesions were (4.75±2.62) cm, (5.37±3.11) cm and (4.96±3.82) cm, respectively.There were no statistical difference in lesion''s size among these three types(F=0.247,P=0.782).(2)On the mammograms of these 44 PTs(including 16 cases of benign type, 18 cases of borderline and 10 cases of malignant type), the appearances of radiolucent halo and calcification among these three types showed statistically significant differences(both P<0.05).(3)On the sonography of these 61 PTs(including 19 cases of benign type, 26 cases of borderline and 16 cases of malignant type), the shape among these three types showed statistically significant difference(P<0.05).(4)On the MRI of these 61 PTs(including 21 cases of benign type, 24 cases of borderline and 16 cases of malignant type), internal hypointense septations on T2WI and time intensity curves showed statistically significant differences among these three types(both P<0.05).Conclusion Some radiological appearances of PTs can be used to help determine the histologic subtypes of breast PTs preoperatively.
