Background. Granulosa cell tumor (GCT) accounts for roughly 1.5% of all ovarian neoplasms and 5-10% of ovarian cancers, GCT, which may have profound end-organ effects, has attracted a significant amount of attention despite its rarity. This tumor is rare, and difficult to diagnose before operation. Until now, no specific sonographic findings have been reported.
Methods. Twelve cases of pathologically proven GCTs were diagnosed from June 1985 to March 1993, Nine of those cases had preoperative sonographic pictures taken.
Results. Eight out of the nine cases tested exhibited a complex multicystic sonographic pattern. For a case evaluated by a transvaginal color and pulsed Doppler assessment, the blood vessels located in the central part with diffuse dispersed vascular arrangement were found to have a resistance index of 0.38 and a pulsatility index of 0.50. The most common complaints of our patients were postmenopausal bleeding and lower abdominal pain.
Conclusions. We conclude that complex multicystic sonographic features observed by high-resolution ultrasonography, in conjunction with a high preoperative estradiol level and clinical symptoms, may help to establish a preoperative diagnosis of GCT.
