persistent trophoblastic tumorFrom: Rich Dempsey RDMS/RVT (ridem@msn.com)Tue Sep 30 16:45:05 2003
Any one have information about the Doppler waveform for this type of GTD? Patient was 4 weeks post elective AB (7 wk GA embryo) with continued bleeding. A relatively small area of endometrium had a complex appearance with a 3mm echogenic mass. With color Doppler this appeared highly vascular. The RI was 0.4, PSV 50cm/s . For obvious reasons this wasn't angle corrected, however sample gate was 2mm, and the beam was (presumed ) to be perpendicular. OF COURSE bHCG was not available at time of scan. I have seen a fair number of RPOC (retain products of conception) confirmed by pathology. None had this vascular pattern, or appearance. I'm assuming the physician will also check hPL ( palacental lactogen) , though I realize that these type of tumors are so rare as to be unlikely. Can RPOC have a similar (Doppler) appearance?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
