MRI and FDG PET/CT Findings for Borderline Brenner Tumor of the Ovary: A Case Report and Literature Review

Figure 1

MR findings for the borderline Brenner tumor in a 54-year-old woman. (a) The axial T2WI shows a unilocular cystic tumor in the pelvic cavity which was 9 cm in diameter with two solid components. The cystic content has the same signal intensity (SI) as water. The solid mass located at the anterior wall (white arrow) shows low SI similar to the SI of muscle. The papillary tumor on the left side of the solid mass (black arrow) shows an intermediate SI, slightly higher than the SI of muscle. (b) The axial T1WI shows the cystic content has slightly higher SI than water. The solid mass shows slightly lower SI than muscle. The papillary tumor on the left side of the solid mass shows low SI, similar to the SI for muscle. (c) Gadolinium-enhanced fat-saturated T1WI shows the solid mass is slightly enhanced and the papillary tumor is well enhanced. (d) Axial DWI (, 1000 s/mm²) shows a solid mass with a low SI and the papillary tumor with high SI.
