Mature cystic teratomas of the ovary are a common ovarian neoplasm, particularly in young patients. The majority of these neoplasms are benign; only a small minority demonstrates malignant potential. Distinguishing benign from malignant tumors is difficult on imaging alone, but has important clinical implications with regards to follow up and surgical excision. This study is the first in the literature to describe the incidence of, and type of, noduar enhancement within benign mature cystic teratomas. Fat containing ovarian lesions with an internal nodule demonstrating peripheral enhancement and internal fat, along with acute angles and lack of extension beyond the cystic wall, can be confidently diagnosed as having a benign nodule and thus compatible with benign mature cystic teratoma.
