Dear Ana,

Firstly, I would like to encourage you to post some images in the informal case studies. A picture is worth a thousand words.

In the next couple of weeks, I am posting a case-study regarding a rare finding of fetal hepatic hemangioendothelioma. The reason I am mentioning it now is the fact that when this anechoic irregular liver mass was first seen on an antenatal scan (in a different laboratory), it was assumed to be an abnormality of the gallbladder/ biliary system. Only later on in the pregnancy was the fetal liver evaluated with color and Pulsed doppler which showed perfuse vascularity of the lesion therefore effectively ruling out biliary tree dilation/ gallbladder/ choledochal cyst scenarios. Hemangioendotheliomas can produce fetal hydrops, since they can act as AVMs and promote CHF (although this should be accompanied by other signs such as heart enlargement, body wall edema, etc). There is some similarity between the case you describe and the case-study which I am preparing.

Are you certain the structure you are seeing is the GB? Did you use Color Doppler to evaluate the area? Would you be able to post some images for us to review?

Many Regards,

Martin Necas, RDMS, RVT Waikato Hospital, Hamilton, New Zealand.

Dear listers,

I'm a sonographer in a Maternity in the north of Portugal. I'm posting a case to wich I would like to ask for your expert opinion: Single fetus, at 14 weeks presents with ascitis, distended bladder, oligohydramnios. At the following visit at 16 weeks, no ascitis was visible and there was some LA, cariotype - 46, XX. Presently she is 20 weeks, has a distended bladder somewhat irregular in shape and with hypertrophic wall. Renal parenchima seems normal and there is no hydronephrosis, LA is normal.

What should we look for next? Is there a way to establish the prognosis in this case?

Thank you in advance for any help,

Ana Cunha, MD Maternity Julio Dinis Porto - Portugal
