What is your diagnosis based on these images of the ovary?

This lesion, also known commonly as a dermoid cyst, appears as a well-defined cystic lesion with posterior acoustic enhancement with echogenic debris within the cyst. In addition, there is an echogenic nodule producing posterior acoustic shadow; this is a calcified nodule. Together, these findings suggest mature cystic teratoma of the ovary.
