Ovarian teratoma isteratomas are usually asymptomatic and often discovered incidentally.

CT images demonstrate the typical radiological finding of mature cystic teratoma: fat-fluid level, calcification and Rokitansky protuberance.

The mass has a maximum diameter less than 10 cm and regular borders, indicative of benignity.

"Pareidolia" is the phenomenon of perceiving a stimulus (like an image) in random everyday objects or a familiar pattern of something: in. In this case, the ovarian teratoma can be compared to a "Poké Ball".
