Objective: To describe the CT characteristics and improve pre-operative diagnosis of fibrothecoma and fibroma of the ovary.
Methods: The clinical and CT image material of 14 postmenopausal patients with pathologically confirmed fibrothecoma or fibroma of the ovary were reviewed.
Results: Of the 14 cases, 7 had ascites. The tumor was solid in 10 cases, cystic or cystic-solid in 2 cases. It was round or elliptic in 9 cases, multilobular or irregular in shape in 5. In all cases, the tumors had clear border. On CT imaging, the solid tumor, the solid part of the cystic-solid tumor, and the cystic wall were similar in density to that of myometrium on precontrast scanning. There was no or slight uptake on postcontrast enhancement, the density of which was obviously lower than that of myometrium. In tumors heterogeneous in density, low density areas of light flakes or streaks were observed. In cystic or cystic-solid tumors, the demarcation between the cystic and solid portion was clear. Nodules on cystic wall were visible.
Conclusion: CT is useful in the diagnosis of the fibrothecoma and fibroma of the ovary.
