Aim To evaluate the accuracy of transvaginal sonography with color Doppler (TVSCD) in identifying mucinous ovarian cysts. Material and methods Five hundred 18 adnexal masses were diagnosed by TVSCD before surgery. We identified those adnexal masses in which an ultrasonographic diagnosis of mucinous ovarian cyst was done. This diagnosis was based on the presence of a cystic lesion with thin, grape‐like appearing septa and diffuse internal echoes. This diagnosis was compared with the pathological features. Results A total of 49 mucinous cysts were diagnosed by TVSCD, 26 of them were histologically confirmed. Twenty‐three cysts were misdiagnosed (9 were serous, 4 were interpreted as malignant and one was an endometrioma). TVSCD was unable to diagnose 14 out of 40 mucinous cysts confirmed by histology. The ultrasonographic features most frequently seen as suspicious of malignancy were thin, grape‐like appearing septa (84.6%) and diffuse internal echoes (53.8%). The sensitivity, specificity, and positive and negative predictive values and accuracy of TVSCD were 65%, 95.2%, 53.1%, 97%, and 92%, respectively. Conclusions The accuracy of TVCD for the diagnosis of benign mucinous cysts is very high, being the most frequently cause of confusion simple serous cysts.
