Abstract:
Objective To observe CT features of struma ovarii (SO) in comparison of pathologic findings. Methods CT features of 9 patients with pathologically confirmed SO were analyzed retrospectively and compared with pathological findings. Results All tumors were unilateral and had smooth margins, 3 were cystic and 6 were cystic-solid lesions, 5 were high attenuation lesions in the cyst portion of the mass on contrast CT. The cyst wall moderately (n=3) or markedly (n=5) enhanced after administration of contrast medium. Scattered, stripe-like or ring-like calcifications were found in 6 patients. On pathology, most of cystic portions were filled with high proteinaceous gelatinous fluid of eosinophiclic colloid, and the solid portion of tumors consisted of the thyroid tissue and stoma containing abundant blood vessels and fibrous tissue. Conclusion SO appears as a smooth marginated multicystic mass with calcification, high attenuation lesionin plain CT, and marked solid part enhancement on contrast CT.
