so this is a case of a male muted 11 year old Staffordshire Bull Terrier weighing 23 kilos he presented with a history of diagnosed hyperadrenocorticism but the Vets dealing with him were having real difficulty in stabilizing him so during the scan I wanted to focus um heavily on looking at the adrenal glands for this reason we did scan the whole abdomen but I will focus on what our findings were on the left adrenals so here we've got from the left hand side we've got the aorta closest to the probe and then the cordovina cave are just slightly further away this is a moving image here um so we can see that there's some something hypoechoic here in this region and we can see that the vessel extends from the aorta up around it and that vessel is the left renal artery and just cranial to it we've got this large hypoechoic structure um and and that is in the region of the left adrenal gland so a little bit closer here we can see the aorta and the cordovina Cava and then we've got the left renal artery coming round and here we've got the chordal pole of the adrenal gland with the cranial pole just ahead of it here here again we have the cranial pole of the adrenal gland and the caudal pole which is massively enlarged here again cranial pole and chordal pole and we can just make out the frenico abdominal vein which crosses between those two poles of the left adrenal applying Doppler we can really see the left renal artery looping around the adrenal gland and we can see the aorta down here we're looking for any turbulence in the blood vessels any sign of invasion into the local blood vessels there and there's Nancy so here we are measuring the chordal pole of the left adrenal gland so in a dog weighing uh 23 kilos as this dog does I'd expect the left adrenal to be around the half centimeter Mark um but in in this dog it was measuring at um 2.75 centimeters so massively increased in size here we're looking at the right adrenal for comparison so here is the right adrenal we've got the cordovina Cava coming across over here and we can see the a water in the left renal artery over here popping into view occasionally but this structure here this hypoechoic structure is the right adrenal and we can see it's much smaller than the left adrenal was again you can see the cool vena cava coming across uh in this cine Loop so we'll see that here and then the right adrenal line right up against it it's sort of L-shaped uh this is one arm of it um The Cordial arm so here we can see the the bright adrenal again popping into view just here so here we can see we're measuring the right adrenal in comparison and this was measuring at 0.4 centimeters so right around what I'd expect a left adrenal to be in a dog this size possibly even slightly reduced and that can happen if the other adrenal gland is is um over functioning then it can sort of atrophy a bit um so yeah 0.4 centimeters for this adrenal gland so the difference between the the left measuring 2.75 centimeters compared to 0.4 centimeters on this side is is huge indifference so this case was an adrenal dependent hyper adrenocorticism it's likely due to a primary functional tumor in this case we didn't see any local Invasion or metastases so surgical resection of the left adrenal gland was likely to have a a positive outcome in this case foreign
