Findings

Left and right lateral, ventrodorsal, and dorsoventral radiographs are available for review. There is moderate pleural effusion present with rounding and retraction of the lung lobes. In addition, there is a mass effect between the cardiac silhouette and the diaphragm in the caudoventral thorax. This appears to be a mass in the right caudal lung lobe on the ventrodorsal projection. The region of the accessory lung lobe also appears more opaque. There are small gas bubbles visible on the right lateral projection which may be in the pleural space or within the mass. There is a triangular shaped projection at the left cranial cardiac silhouette on the ventrodorsal projection which may represent a reverse fissure line, indicating fluid in the mediastinum. The crannial a mediastinum appears widened on the dorsoventral projection.
