Findings of gray scale ultrasound were analized in 106 surgically proven cystic masses of ovary. Sonographicdifferential diagnosis was attempted on the basis of size, definition of border and internal consistency of themass. Cystic masses of ovary coule be subcategorized into 4 groups: homogenous cystic mass, cystic mass withinternal septation, cystic mass with solid foci, and cystic mass with low level internal echo. The resultsobtained were as follows: 1. 62% of mucinous cystadenoma(13 cases) were cystic masses with internal septation. 2.62% of serous cystadenoma(21 cases) were homogenous cystic masses. 3. 14 cases of corpus luteum cyst were 13homogenous cystic masses and 1 cystic mass with septation. 4. 7 cases of endometriosis were 3 homogenous cysticmasses, 3 cystic masses with internal echo and 1 cystic mass with solid foci. 5. 63% of cystic teratoma(30 cases)were cystic masses with solid foci. 6. 11 cases of incorrect diagnosis as ovarian cyst were 4 uterine myomas, 2abscesses in iliac fossa, hematoma, hydrosalpinx, mesenteric cyst, distended urinary bladder, etc.
