It's location caudal to right kidney, could be ovary - judging by the caudal bit of the kidney it doesn't appear enlarged. Appears hyperechoic with acoustic shadowing suggesting mineralisation (anal gland adenocarcinomas often cause hypercalcaemia?) compared to those I'm used to seeing (usually anoestrus) and also has a hypoechoic area within it. I'd be concerned about metastases or mineralisation due to the acoustic shadowing. Looking forward to hearing the real answer!

The shadow is a dirty shadow which is suggestive of gas. The location is in the area of the ascending colon. I would want to find a clear image of the colon and try to follow it to this area to see if it is related. The hypoechoic focal area in the hyperechoic region is odd looking and may represent a lesion even if this is the colon.

ovario calcificado o necrosis grasa????????????

i think that it is an incidental finding. Most of the anal adenocarcinomas go to the sacrum linph nodes, and it doesen´t appear to have mass effect

if it's a female than postoperative scar/fibrosis/granuloma after right ovary removal might be possible.
Other differential could be lymphadenopathy of the lumbar aortic lymphadenopathy
FNA could aid in diagnosis

My guess it is a Bates body - incidental mineralizing region of necrotic fat

thank you very much. very interesting

I honestly do not understand why this dog went to CT to identify this potential lesion. Before going to that expense to the owner, a linear transducer should have been adopted and included with the scan. I am sure that Elastography is available to you so that at a click of a button, the stress pattern it produced would have suggested something more benign. This result could have easily been compared to that of the carcinoma if you were still hesitant of it's nature. Finally there is no Doppler flow information presented to us here. This would have proven itself to be invaluable in making an informed decision. It would have also confirmed that the finding wasn't clinically significant in any way in this case. Sorry to be critical, I hope that I do not appear to be disrespectful in any way. Thank you for sharing your interesting cases with us,sincerely,Bob.

Thank you for sharing your thoughts. Actually, as indicated in the clip, the CT was performed as an oncology follow-up and NOT for evaluating this change. As the dog received radiation therapy, the CT was part of the protocol (done 6 months after the US-and the lesion had not changed in size over several months). I spared you the details as it was beyond the scope of this case but I'm glad you gave me the opportunity to tell you more...The change outlined in the clip would NOT be a good reason to perform a CT scan.
Also, I placed a color-flow image that did not show any vascularization; you are right, it is useful to know that.
Bob, could you share your personal experience on elastography, and especially of this type of lesions? Do you have any good reference that could benefit the readers?
