This week’s case is a 5-year-old dog with persistent pulmonary infiltrates. This one is subtle. Can you see the infiltrates?
Findings
On the right lateral projection, there is an ill-defined region of increased opacity superimposed over the heart. This is visible on the ventrodorsal projection in the left caudal lung lobe. The pulmonary parenchyma is otherwise normal. The cardiovascular structures are normal in size and shape. There is mild increased opacity dorsal to the second sternebra.Differential Diagnosis
- Pulmonary infiltrates – DDX granuloma, pneumonia, abscess (possible relation to ingested foreign body 4 months previously).
Diagnosis
On CT imaging, a hypoattenuating linear structure (bamboo skewer) surrounded by contrast-enhancing soft tissue extended from the wall of the fundus, through the liver and diaphragm, and into the left caudal lung lobe. The foreign body was surgically removed.
