12 year old Siamese

by Allison Zwingenberger on September 2, 2010

For the next few weeks, I’m going to present cases from a talk I did at ACVIM this year on thoracic ultrasound. I hope you enjoy them!

The first one is a 12 year old female spayed Siamese cross with several weeks of increased difficulty breathing. Take a look and post your interpretations.

On the lateral view diaphragmatic border is obscured in the middle. Trachea seems to be deviated ventrally by a homogenous mass dorsal to it. There is severe increase of opacity in the lung fields, best seen in caudal lung lobes. There are gas field areas overlying thoracic region, both in the caudodorsal and caudoventral regions. Cardiac silhouette is also obliterated. Gastric fundus is visible caudal to the diaphragm, however, liver cannot be seen in whole.
Differential diagnosis should include;
Hiatal hernia, including paraaortic hernia, with the liver displaced into the thoracic cavity. There should be a possibility for some bowel loops or a part of the stomach to be displaced into the thorax.
