[Imaging Findings of Ovarian Fibrothecoma].

OBJECTIVE

To summarize the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of ovarian fibro the coma and to compare them with the pathological findings.

METHOD: CT and MRI features of 25 patients with pathologically proved ovarian fibrothecoma were retrospectively analyzed.

RESULTS

Of these 25 patients,the tumors were single in 23 patients and bilateral in 2 patients. The tumors were round or oval in 16 cases and lobulated in 11 cases. CT plate scanning showed that both the solid masses and the solid components of the cystic and solid masses had slightly lower densities than that of the myometrium, and gradual and mild enhancement could be found in the arterial phase and delay phase after enhanced scan. MRI showed iso-low signal on T1-weighted imaging, slightly low or high signal on T2-weighted imaging of fat suppression sequences, slightly high signal on diffusion weighted imaging and the enhance characteristics as the well as CT after enhanced scan.Pelvic cavity effusion was seen in 3 cases.

CONCLUSION

Ovarian fibrothecoma have certain imaging characteristics,which are helpful to improve the diagnosis and differential diagnosis of this disease and lower the misdiagnosis rate before operation.
