Figure 18.4 Ventrodorsal (a) and lateral (b) images of the thorax of a cat with unilateral pleural effusion. The large volume of
left-sided effusion results in a mediastinal shift to the right on the ventrodorsal view. The trachea is markedly elevated on the lateral
view, secondary to the large volume of pleural effusion. No mediastinal mass was present. FIP was suspected from cytology of the
pleural fluid.

Figure 18.5 Lateral (a) and ventrodorsal (b) images of the thorax of a cat with cranial mediastinal lymphoma. Pleural effusion is
noted bilaterally, although more severe on the left side, where a widened, radiopaque pleural space is noted. The cranial mediastinum
is widened on the VD view, and the trachea is elevated on the lateral view. These changes are suggestive of a cranial mediastinal mass
but additional imaging, such as ultrasound or CT, would be necessary to confirm the presence of a mass. A cranial mediastinal mass
was detected on thoracic ultrasound, and lymphoma was diagnosed with a fine needle aspiration.
