Findings
Orthogonal radiographs of the thorax are available for interpretation.
There is marked right atrial and right ventricular enlargement resulting in increased sternal contact and widening of the cardiac silhouette. There is marked dilation of the main pulmonary artery resulting in abaxial displacement of the left cranial lobar bronchus. The right caudal lobar pulmonary artery is markedly dilated and tortuous. The left caudal lobar pulmonary artery is markedly distended.
There is a moderate diffuse bronchial and unstructured interstitial pattern. Several small, pinpoint mineral opaque foci are noted throughout the pulmonary parenchyma, consistent with incidental benign osteomata.
The liver is mildly enlarged, extending beyond the costal arch with rounded caudoventral margins.
There is multifocal in situ thoracic intervertebral disc mineralization. Spondylosis deformans is noted at the T10-T11 intervertebral disc space.
Diagnosis
- Marked right-sided cardiomegaly, main pulmonary enlargement and enlargement and tortuosity of the caudal lobar pulmonary arteries is consistent with the reported pulmonary hypertension which may be secondary to heartworm disease, primary lung disease or idiopathic. Considering the severity of the described changes, repeat heartworm testing is recommended.
- Pulmonary changes may be age related or may be secondary to chronic lower airway disease. Airway sampling could be performed for further evaluation.
- Mild hepatomegaly is nonspecific and may represent benign or malignant etiologies.
- Multifocal thoracic intervertebral disc degeneration.
Discussion
The patient was confirmed to have pulmonary hypertension on echocardiogram.
