OBJECTIVE: The purpose of this series was to describe the transvaginal color pulsed Doppler sonographic features of epithelioid trophoblastic tumors (ETTs) and to evaluate whether there were specific sonographic criteria to accurately distinguish them from other lesions. METHODS: Seven cases of ETTs treated in the Women's Hospital of Zhejiang University were retrospectively analyzed. Doppler indices, including the Pourcelot resistive index (RI), pulsatility index (PI), and peak systolic to diastolic velocity (S/D) ratio from blood flow signals within the tumors were calculated from each waveform sample by using the software of the ultrasound machines. RESULTS: Patients with ETTs had heterogeneously echoic masses and highly abnormal flow patterns. The mean PI, RI, and S/D ratio for the patients were 0.57 (range, 0.22-1.09), 0.42 (range, 0.2-0.7), and 1.89 (range, 1.25-3.40), respectively. CONCLUSIONS: The clinical usefulness of intratumoral blood flow assessment in ETTs is yet to be established. However, the multiparameter sonographic approach can help in diagnosis of an ETT. |
