Although abdominal computed tomography (CT) performed at that point had revealed a mature cystic teratoma measuring 6 cm in diameter in the right ovary, it was left untreated. She visited the department of surgery at our hospital with chief complaints of appetite. A teratoma can also be vascularized if it is malignant. With experience, ultrasound operators can easily distinguish between normal and increased vascularity in the adnexa, and recognize when an increase might signal an inflammatory process rather than a malignancy.

Examples include teeth growing inside the lungs, or bone growing inside an ovary. Teratoma is common in newborns (neonatal teratomas) [2] and females. If it occurs in a newborn, it is usually benign (harmless) and can be removed surgically.
