A first calver dairy cow that has calved 6 months ago and that is not inseminated has recently decreased in production and appetite. She has been examined ultrasonically. The liver appeared to be congested with enlarged anechoic structures interpreted as congested bile ducts and enlarged congested gall bladder. What could all the potential differential diagnoses be?
I would try to rule out liver congestion (ie enlarged vessels) using a color Doppler exam.
That sounds like a very good idea, thank you!
Could it also be some tumour when it is visualised as a big round anechoic structure ventral of the liver with some hyperechoic-hypoechoic small structure visualised inside?
I would firstly think to either an abscess or a hydatid cyst rather than a tumor (higher probability).
