ABSTRACT

PURPOSE: To describe ultrasonographic findings of ovarian granulosa cell tumor (GCT) and to determine their possible value in the differential diagnosis of ovarian tumors. MATERIALS and METHODS: Sonographic appearances of ten cases of pathologically proven GCTs were retrospectively reviewed regarding their location, size, outer margin, the echo pattern of the tumor, endometrial thickness, presence of ascites, and metastasis to adjacent tissue or distant sites. 3.0 - 3.5 MHz trans- abdominal US or 5.0 -6.5 MHz transvaginal US were used. RESULTS: The sonographic features could be classfied as follows : unilocular cystic mass without nodule or septation (type 1), multilocular cystic mass (type 2), and solid mass (type 3). Pathologically nine cases were adult type granulosa cell tumor (GCT) and one was a juvenile type. All cases were unilateral. GCT arising from left ovary were seven, right, three. The largest diameter of the tumors ranged from 6.8 to 24cm (mean:11.9cm). All had well-defined margins. Ascites was seen in four cases. Among ten cases of GCT, six were mainly solid (type3). One case manifested as a unilocular cystic mass without mural nodule or septation. Three were multilocular cystic masses and no mural nodule was found in all three cases. Metastases to peritoneum and lymph nodes was seen in one case. CONCLUSION: The ultrasonographic findings of GCT are various but combined with clinical and laboratory findings they could be helpful in the differential diagnosis of ovarian tumors.
