Mature cystic teratoma are the most common neoplasm of the ovary which includes at least two well – differentiated germ cell layers.

However due to the presence of fat and calcification which forms the predominant content of the lesion, these tumors are readily identified by CT. However they are rarely missed on USG and MRI due to its classical tumor components and signs which were reported in various studies in the past. In this case report we presented a classical but rare presentation of cystic teratoma which was diagnosed by CT with further characterization by MRI
