Heart ultrasound image of the thoracoabdominal region of an 8-month-old neutered female domestic mixed breed cat with persistent coughing, mild asphyxia, nasal discharge, and physical activity intolerance via a subcostal window. Yellow arrow indicates hepatic parenchyma tissue and two-way yellow arrows indicate its edges.

The pericardial sac had adhesion to the liver lobe, however no effusion was observed (Figure 1).
Thoracic radiographs of an 8-month-old neutered female domestic mixed breed cat with persistent coughing, mild asphyxia, nasal discharge, and physical activity intolerance. (a) Left lateral, (b) right lateral recumbency and (c) dorsoventral projections. Panel a-c shows an enlarged cardiac silhouette with cardiomegaly before surgical intervention. The cardiac silhouette merges with the diaphragmatic outline and loss of diaphragmatic border. There is a lobulated soft tissue opacity in the caudal thorax just right of the midline at mid-height, with a broad base to the diaphragm (asterisk). White arrowheads indicate the loss of diaphragmatic margins. The caudal vena cava is not visible. Left lateral (d) recumbency thoracic radiograph after herniorrhaphy and thoracic tube placement. Black arrowheads indicate the integrity of the diaphragm after the surgical procedure.

Plain thoracic radiography revealed a broad-based, round dome shaped, shadow in the chest cavity (Figure 2). This contrast-enhanced tissue was broad-based and was in contact with the adjacent diaphragm (Figure 2).
Ultrasound image of the thoracoabdominal region of an 8-month-old neutered female domestic mixed breed cat with persistent coughing, mild asphyxia, nasal discharge, and physical activity intolerance via a subcostal window. There is an interruption in the diaphragmatic interface (dotted line), with herniation of hepatic parenchyma (asterisk).

Observing the diaphragm, it was visible absence of the echogenic diaphragmatic landmark centrally and identified cranial displacement of a portion of the liver into the caudal thorax, continuation of the liver parenchyma attached to the pericardial sac (Figure 3).
