Case Study

RADS – Broncoalveolar Lung Pattern, Bronchitis vs Neoplasia in a 14 year old FS Cocker dog

History of respiratory difficulties. PE: increased respiratory rate (40); abominal breathing. CBC and Chem WNL.

Image Interpretation

right lateral, left lateral and VD thorax and abdomen: Osseous structures: There were moderate degenerative changes including
spondyloses level with the intervertebral disc spaces T11/12, L2/3.
Overall the degenerative changes associated with the axial sceleton were
mild to mdoerate.
Extrathoracic/-abdominal soft tissues: Within normal limits.
Abdominal Structures:
The serosal detail was normal.
The liver was within normal limits.
The stomach presented moderate aerophagia which likely was a function
of respiratory distress here.
Intrathoracic structures:
The esophagus was not seen.
The course of the trachea was normal.
There was no mediastinal widening and no evidence of mediastinal
lymph node enlargement. There was no mediastinal shift.
The cardiac silhouette was within normal limits. The major and
pulmonary vessels were within normal limits.
The lungs presented a severe generalized bronchoalveolar pattern with
peribronchial cuffing and confluent parenchyma consolidations. A
miliary pattern was noted in some areas. There was mild pleural
thickening and marked generalized bronchial wall mineralization.

DX

The radiographs revealed a severe generalized broncoalveolar lung pattern with miliary component. Even if lower for potential according to the distribution of changes and marked bronchial wall mineralization,primary bronchoalveolar or secondary neoplastic infiltrate such as a metastatic pattern or round cell neoplasia has to be considered also.
