Ovarian serous cystadenoma


Pathological specimen reveals ovarian serous cystadenoma.

DWI can provide an adjunctive tool to differentiate the benign and malignant ovarian lesions. Malignant lesions tend to induce diffusion restriction with ADC value < 0.9 x 10-3 mm2/s, the vice versa for the benign lesions. Absence of enhancement of the solid component and absence of diffusion restriction are supportive of benignity.
