Abstract:
Objective To analyze the imaging manifestations of malignant transformation of ovarian mature teratoma.Methods The clinical data and CT and MRI imaging findings of four patients confirmed as malignant transformation of ovarian mature teratoma by operation and pathology were analyzed retrospectively.The following imaging features were assessed:size,shape,texture,enhancement degree and pattern,et al.Results Among the four cases,three lesions were located in the left ovary and one in the right ovary.The minimum size and maximum size were 87 mm×80 mm×87 mm and 171 mm×141 mm×215 mm,respectively.All of the lesions showed as round-like or ovoid cystic masses with fat-fluid level(4/4),and floating mixed density or signal masses(2/4).The demonstrated local thickening of the cyst wall(2/4)and/or soft mass growing across the wall(3/4),with significant inhomogeneous enhancement(2/3).Conclusion The malignant transformation of ovarian mature teratoma often presents as a cystic mass with fat-fluid level,and local thickening or soft mass of the cyst wall,with significant enhancement.It should be considered in the elderly patients with abnormal tumor markers and above imaging features.
