This adult female patient presented with a pelvic mass. What's your diagnosis?

Teratoma is a neoplasm composed of multiple germ layers, such as the mesoderm, endoderm, and ectoderm, that result in solid and cystic components. The mass can grow extremely large and may contain bone, skin, fat, and hair, giving a bizarre appearance on ultrasound. In this patient, the teratoma is seen to be huge with a large echogenic solid component surrounded by fluid fatty matter.
