CT and pathologic analysis of ovarian fibrothecoma / 实用放射学杂志

ABSTRACT

Objective To explore the CT features and differential diagnosis of ovarian fibrothecoma,and to compare with postoperative pathological findings.Methods The clinical data,CT appearances and pathological signs of 15 patients with ovarian fibrothecoma and 7 patients with granulosa cell tumor were analyzed retrospectively.The plain CT values and enhanced CT values(ΔCT)of fibrothecomas and granulosa cell tumors were compared with each other.Results The ovarian fibrothecomas showed solid or cystic-solid masses with well-defined margin,mild delayed enhancement or no obvious enhancement on CT.The CT features were correspond to the pathological signs. The plain CT values of fibrothecoma and granulosa cell tumor had no significant difference(t=0.745,P=0.467).The mean ΔCT values of fibrothecoma was significantly lower than that of granulosa cell tumor(t=2.537,P=0.041).Conclusion Ovarian fibrothecoma has characteristic CT features,combined with the clinical data,which may help to improve the diagnosis.
