Left ovarian lesion with fat density and chunks of calcification.
Usually, mature cystic teratomas are asymptomatic, however, nonspecific symptoms might occur in some patients with the mean age of the affected group 30 years. CT findings of mature teratoma are fat attenuation within a cyst and may be associated with calcification in the wall or a fat fluid interface may be encountered.
On the contrary, an immature cystic teratoma usually happens in a younger age group, mostly the second decade. They are less common and have a malignant tendency. Immature teratoma may be bilateral and may be associated with mature teratoma of the contralateral ovary. Immature teratomas tend to be larger in size with heterogeneous solid appearance. A small amount of fat and calcification can be demonstrated within the lesion.
