Figure 4 : Dermoid. Transvaginal ultrasound (a) demonstrates a complex cyst with an echogenic mural nodule (arrow). Axial MRI T1 weighted images without fat saturation (b) demonstrate hyperintensity (arrow) that loses intensity with fat saturation sequences (c) indicating presence of macroscopic fat
