Hi all,
Fatty is an oldish female entire guinea pig presented with marked weight loss, abdominal distension, marked bilateral symetrical alopecia. owner not sure whether Pu-PD. I do not have urine sample nor blood work nor Xrays. Referring vet wants to rule out ovarian cystic disease or HAC.
US findings: no ovarian cysts nor uterine abnormalities seen. Abundant free fluid found. Liver appears hyperechoic and with hyperechogenic focci which do not have distal echoshadowing (although really small, so might not produce). i suspect more fibrosis focci (?)

Left adrenal normal in shape and echostructure. Size…0.5cm aprox medulla appears quite echogenic and cortex a bit hyperechoic, but appears normal to me.
Right adrenal: depending on the view, it looks like measuring up to 0.89cm on caudal pole transverse and there is a clear CVC distension. Well, actually, I am not so sure, so this is my question. I think there is CVC distension and I suspect it is coming form right adrenal invasion, however, I cannot see clearly an intraluminal mass. I am blaming the free fluid to CVC obstruction…There is no clear signs of biliary obstruction so I dont think the dilation is actually a bile duct distension…and its right at the adrenal point…
Any input is welcome. Also…what about liver…how do I interprete the findings? IS fibrotic disease common in guinea pigs?
Thanks for your help.

hmm not sure here but would be helpful some sweeps of the portal hilus from a suxyphoid position.
That adrenal does look irregular and the cvc is focally dilated and the hepatic veins are dumping cranially into the cvc in a solid fashion as if its a collateral circulation of excessive volume.
if you turn him over on the left side and scan right intercostal positions 12-14 on the 17 point sdep protocol (http://sonopath.com/products/poster) with wide sweeps it may help more as this is a 3 dimensional pathology that we are imagining in 2 dimensions so at times we need to do a pancake flip or 2 to create a circumferential visual owing to organ discplacement.
The free fluid is not likely completely from cvc obstruction because there is collateral circulation throught the portal system (ferrets are artists at this of course) at the end of the 3rd video and the residual cvc has flow through the d-inlet ok in video 2. Would be good to tap the fluid to see its nature whether pure transudate or other.
Cool post
Thanks for your input. I
Thanks for your input. I remember having done that view, I turned the ghinea pig in all imaginable positions!but she was not too cooperative even for the easy ones which made me think that she was sore and may be that fluid is not just obstructive flow. I’ll review my images and see if I can show you more. Any ideas on the liver findings? Ah, the GB has significant sediment but I think it may be normal. I can’t find enough information about normal guinea pigs ultrasounds. I must admit the lover and GB Look different from the other guinea pigs I have scanned.
Thanks EL.
I checked the videos. The
I checked the videos. The subxiphoid view was not showing anything due to large GIT content and gas shadows. I will post a video of Portal vein but it is not from the intercostal space. She was very sensitive to probe.
