Abstract:
PurposeStruma ovarii (SO) is rare and has no typical symptoms, which is likely to be misdiagnosed before procure. The present study aimed to evaluate multi-sliced CT (MSCT) findings of struma ovarii so as to improve its imaging diagnosis.Materials and Methods The clinical and radiological data of 25 patients with struma ovarii confirmed pathologically patients were retrospectively analyzed and further compared with the pathological results after procure.Results For 25 SO patients, 22 (88%) had unilateral lesions and the rest 3 (12%) had bilateral ones; 11 lesions (44%) were cystic, 8 lesions (32%) were cystic-solid, and 6 lesions (24%) were solid. The CT images of 8 lesions showed high density cystic lumens. Twenty-five tumors had smooth margins, which appeared round, ellipse or irregular. The pathological findings showed that most of the cystic portions were filled with high proteinaceous gelatinous fluid and eosinophiclic colloid, and the solid portions consisted of thyroid tissue and stoma containing abundant blood vessels and fibrous tissue.Conclusion SO has the MSCT features such as cystic solid mass with unilateral and smooth margin, capsular space with high density, calcification, and solid parts with obvious enhancement.
