Figure 4: Dermoid cyst with small amount of fat. Axial T1- (a) and T2-weighted images with fat suppression (b) show a complex cystic round lesion with a hypointense nodule (a, b, white arrow) on the right side arising from the right ovary. Observe ovarian parenchyma with small follicles (b, void arrows). A linear T1 hyperintense portion is located on the upper part of the cyst (a, void arrow). The corresponding axial fat suppressed T1 weighted image shows the vanishing of the hyperintense part (c, arrow) confirming the presence of small amount of fat. 3D fat saturated T1-weighted Spoiled Gradient Echo image (d) demonstrates the poor enhancement of mural protrusion corresponding to Rokitansky nodule (arrow).
