2YO FS Shih Tzu with significant weight loss of ~ 3# (was 9# now 6#) despite normal appetite.

There are sonographic changes that indicate that the GI tract is the cause of weight loss.

Chemistries:  mild ALT (172) elevation. Normal ALT and  BUN. Low normal ALB and Glob.

No clinical signs related to the urogenital system.

Two sweeps of the urinary bladder are offered. One in sagittal and the other in transverse. This lesion appears to be located in the dorsal wall at the trigone.  It does not appear to involve the wall layering.  The fluid pocket seen dorsal to the urinary bladder apex  in the sagittal sweep is actually luminal fluid in a small bowel segment.

Any thoughts about what this bladder wall finding represents ?
