This 14 year old FS DSH cat has a recent history of pulmonary nodule found on a pre-dental workup. New soft tissue opacity noted appearing to arise from the mediastinum. Murmur 3/6, hyperthyroid.

CT of the thorax – Multifocal thick peribronchial infiltrates highlight the bronchial tree. Several small well delineated interstitial nodules are seen throughout the lung. Both cranial lobes present ventral peripheral peribronchial alveolar consolidations with focal mineralization consistent with broncholithiasis. The mediastinal structures including the sternal and mediastinal lymph nodes are within normal limits. There is no evidence of a hiatal hernia or other caudal mediastinal soft tissue opacity.
Superinfection and/or decreased mucociliary clearance with peribronchial cuffing, and alveolar consolidation is likely.
For the nodular interstitial pattern fibrotic nodules have to be considered. A secondary neoplasia of the lung is considered less likely especially since they seem to be static reportedly.
The computed tomography does not reveal a hiatal hernia or other caudodorsal mediastinal pathology.
R/O hiatal hernia
