Correlation between imaging characteristics and histopathology in the ovarian thecoma-fibroma / 中国医师进修杂志

ABSTRACT

Objective To explore the imaging characteristics of the ovarian thecoma-fibroma.Methods The clinical imaging characteristics of 25 patients with thecoma-fibroma were retrospectively analyzed. Results A total of 27 lesions were seen in 25 patients, and the maximum diameter of the tumors was 1.2 - 15.0 cm, with an average diameter of 6.9 cm. The tumors whose maximum diameter larger than 6 cm were mainly as cysticsolid. Twenty-six lesions were well-defined margin, and 14 lesions were round and oval masses, 9 lesions were lobulated masses, 3 lesions were irregular masses, and 1 lesion presented with unclear boundary. A total of 10 lesions in 9 cases were performed with CT scan, and the density was similar to uterine muscle density. In MRI scan of a total of 17 lesions of 16 cases, all lesions showed hypointensity on T1WI. On T2WI, 8 lesions showed slightly hyperintensity, 7 lesions appeared slight hypointensity, and 2 lesions appeared significantly hypointense. Eight lesions showed slit hyperintensity. Enhancement scanning was performed in seven cases. Five cases showed mild to moderate enhancement, 1 case was enhanced obviously, and 1 case was not strengthened. Conclusions The imaging findings of the ovarian thecoma-fibroma have somewhat features and can indirectly reflect pathology of tumor. Combined with the clinical data, imaging characteristics are is helpful to the diagnosis and differential diagnosis of the disease.
