The purpose of this study was to evaluate computed tomographic findings of struma ovarii. The following surgical procedures may be considered: Cystectomy or surgical removal of the ovarian cyst, Oophorectomy or removal of the affected ovary, Additionally, chemotherapy and/or radiation therapy may be necessary for malignant tumors, Follow-up care with regular screening and check-ups are important and encouraged, Tumors that behave in a benign manner, with complete surgical removal of the tumor, can have an excellent prognosis, Malignant teratomas may be aggressive, difficult to treat (complete tumor resection may not be possible), and can spread to other sites. In this tumor thyroid tissues are present which covers almost more than 50 % of the total mass present. Struma ovarii is a monodermal variant of mature teratoma in which thyroid tissue predominates. Malignant struma ovarii (MSO) includes tumor types seen in the eutopic thyroid, such as papillary thyroid carcinoma (both the classical type and the follicular variant) and follicular carcinoma.

Coexistence of malignant struma ovarii and cervical papillary thyroid carcinoma. The tissue for diagnosis can be procured in multiple different ways which include: Note: A majority of Struma Ovarii tumors are discovered incidentally.
