Findings

Thorax: There is increased soft tissue opacity in the pleural space with retraction of the lung lobes and partial silhouetting with the cardiac silhouette. There is a patchy bronchointerstitial pattern in the lungs. The cardiovascular structures appear normal.
Abdomen: The abdomen is distended and there is poor peritoneal detail. The liver and spleen are enlarged with rounded borders. The colon is moderately dilated with gas. The small intestine appears normal. The urinary tract is not well visualized.

Differential Diagnosis

Bicavitary effusion may be due to round cell neoplasia, metabolic, or inflammatory disease. The hepatosplenomegaly is most suggestive of lymphoma. Differential diagnoses for the pulmonary pattern include lymphoma and non-cardiogenic pulmonary edema.

Diagnosis

Hepatosplenic large granular cell lymphoma (NK type). The lungs were affected by pulmonary edema.

    why is it pulmonary edema and not pleural effusion? In the lateral projection of the chest it appeared to be pleural effusion

    It is both. That’s why the bicavitary effusion and soft tissue opacity in the pleural space with retraction of the lung lobes and partial silhouetting with the cardiac silhouette was mentioned.

    Another doubt would be in the Dorso-ventral projection of the chest the vessels were very evident in the left caudal lobe. Is this just an effect of the positioning or does it indicate a change?
