Location of images: Thoracic radiographs obtained.

Views of images: Left lateral and ventrodorsal throracic radiographs.


Technical issues: None.

Cardiac size including VHS: VHS 7.2. Cardiac silhouette appear mildly elongated, but this is suspected to be fat in the pericardiacophrenic ligament. There is also an opacity at the cranial base of the heart that is most commonly the ascending aorta/aortic arch, but can be the right auricle of pulmonary artery.Cardiac silhouette appears to have a normal size, except for a opacified bulge near the right atrium. This is generally a difficult area to interpret, as this could be atipose tissue, but given the mildly dilated pulmonary arteries, right atrial dilation must be a consideration. No pulmonary venous congestion, but the pulmonary artery to the cranial lung field (lateral) and to the right caudal lung field (VD) appear mildly distended.Pulmonary infiltrate distribute predominately perihilar and caudodorsal. Pulmonary infiltrate pattern, bronchial. No pleural effusion.

Other Findings: None.

 Radiographic Interpretation: Mild right atrial enlargement with mildly distended pulmonary arteries consistent with pulmonary hypertension. There is also a bronchial pattern consistent with feline asthma.

 Discussion: These films are most consistent with feline asthma and secondary pulmonary hypertension. The history already suggests asthma in an allergy prone cat, so the presence of a bronchial pattern in the absence of any significant interstitial or alveolar infiltrate, strongly suggests feline asthma. Suspicion of pulmonary hypertension would also be high in a patient with chronic respiratory symptoms. An echocardiogram would be needed to confirm pulmonary hypertension.
Treatment/Management: Patient was placed on a 3 week tapering dose of prednisolone 2.5mg every 12 hours, and Albuterol liquid 0.25mg every 8-12 hours.
