MRI diagnosis of ovarian thecoma

Objective: To correlate the MRI findings of ovarian thecoma with pathology. Methods: The clinical features and MRI appearance of 13 patients with 16 ovarian thecomas were reviewed and correlated with pathology. Results: Most of the tumors were round or oval, less often lobulated. T₂ hypointense areas corresponded to abundant fibroblasts in the tumors with scattered T₂ hyperintense areas representing edema or cystic degeneration. The tumors were supplied by ovarian arteries with slight or moderate progressive contrast enhancement. Conclusion: The MRI appearance aids in the diagnosis of ovarian thecoma. (authors)
