What is Transvaginal color Doppler ultrasonic characterization of benign and malignant ovarian cystic teratomas and comparison with serum squamous cell carcinoma antigen about?
## Background: The preoperative diagnosis of squamous cell carcinoma (scc) arising in mature cystic teratoma of the ovary remains difficult. the purpose of this study is to examine the usefulness of transvaginal color doppler ultrasound (tv-cdu) in differentiating malignant (scc) from benign cystic teratoma of the ovary. ## Methods: Eighty-eight patients with an ovarian tumor showing gray scale sonographic appearances of mature cystic teratoma were preoperatively evaluated for the presence or absence of intratumoral blood flow by tv-cdu. the blood flow characteristics of the tumor vessels were analyzed using the resistance index (ri), pulsatility index (pi), and peak systolic velocity (psv). the serum levels of scc antigen were also randomly examined preoperatively in 50 patients. ## Results: Intratumoral blood flow was significantly detected in malignant teratomas (sccs) (80.0%; 4 of 5) compared with benign teratomas (20.5%; 17 of 83) (p < 0.01). all malignant teratomas with intratumoral blood flow showed both ri less than 0.4 and pi less than 0.6, whereas no benign teratomas showed any such value except for 1 case with struma ovarii. in addition, both the mean ri and the mean pi
