What do liver mass, gallstone, and round heart mean on my dog's X-ray?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 10 years and 4 months old | 11 lbs

Just trying to figure out what this means in my dog's report. She received X-Ray/Ultrasound (I understand it's not good) "Liver Mass Suspected/GB choleith, Large Liver, Displaced Stmach, Round heart)."

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. It sounds like your veterinarian is suspecting that Delilah has a liver mass, or tumor, and that the liver overall is larger than normal. This causes the stomach to be displaced, or pushed backward farther than normal. The GB is the gallbladder (an organ near the liver that stores bile), and a cholelith is a stone in the gallbladder, or a gallstone. A round heart can be seen on chest x-rays when there is underlying heart disease. Older small breed dogs such as Chihuahuas are at increased risk of mitral valve disease, which is a degenerative disease of one of the heart valves. This can result in blood leaking backwards in the heart, causing dilation of some of the heart chambers. Often a heart murmur is heard with this disease. An echocardiogram (ultrasound of the heart) is needed to definitively diagnose this. I hope this interpretation is helpful!
