Large heterogeneous mass arising from right ovary, with normal left ovary. The mass contains a large quantity of fat, as noted by the suppression of signal between the T1 and T1FS images. There are also areas of dense calcification and a solid frond-like mass in the left posterior portion. The appearances are in keeping with a large dermoid cyst. There is no free fluid in the pelvis, and no oedema around the mass.
Elsewhere, the uterus contains a gestation sac. The appendix is seen as a high signal structure on the diffusion-weighted imaging but is not distended or surrounded by oedema on the other images, so this is not considered to be acute appendicitis.
