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.
