Case Study

RADS – Pulmonary Osteomas, Pleural Plugs, Hypovolemia, Microcardia and Lung Underperfusion in a 13 year old MN Labrador Retriever dog

Presenting Clinical Signs: Comments: Nystagmus and head tilt, disorientation and cannot walk. Chest films for eval pre-MRI.

DX

The radiographs were within normal limits and negative for metastases. The mineral opaque foci associated with the lung are consistent with pulmonary osteomas and pleural plugs. The radiographs further show hypovolemia with microcardia and underperfusion of the lung. The aerophagia likely is stress- and/or pain-related here. The soft tissue swelling ventral to the sternum likely represents a skin fold

Image Interpretation

right lateral, left lateral and VD thorax:The patient was obese.
Osseous structures: Overall mild degenerative changes were associated with the axial skeleton including emerging Spondylosis deformans T3/4, degenerative new bone at the costochondral junctions and mild spondylarthroses.
Extrathoracic soft tissues: A mild focal soft tissue swelling was noted ventral to the sternum. The serosal detail was normal. The liver was normal for size, shape and opacity. There was moderate aerophagia.
Intrathoracic structures:
No abnormal widening of the esophagus was noted.
The course of the trachea was normal.
The cardiac silhouette covered 2.5 intercostal spaces in width. The major and pulmonary vessels were thin.
There were multiple small and irregular shaped mineral opaque foci distributed throughout the lung parenchyma.
There was a mild generalized age related bronchointerstitial lung pattern.
