Today’s case is a 14 year old male neutered Maine Coon cat with coughing episodes. What are your findings?
The cardiac silhouette is moderately enlarged on all projections and appears base-wide on the ventrodorsal projections. The pulmonary vasculature is normal in size. There is a diffuse bronchointerstitial pattern throughout the lungs. There is mild atelectasis of the right middle lung lobe.
The pulmonary pattern is most likely due to lower airway disease, which may have infectious and noninfectious inflammatory components. A degree of heart failure may be contributing to the appearance of the lungs; however, the vasculature is normal, and the respiratory rate is within normal limits.
Charlierak says
The cat is obese and has a large amount of fat accumulation on the ventral part of the trunk. The pleural space, trachea and esophagus seems okay. The aortic arch and caudal vena cava is in normal size. The cardiac silhouette seems enlarged on the right side with the focal alveolar pattern on it. There is a visible pleural fissure between right middle and caudal lung lobes.
On DV projection, diffuse bronchial lung pattern is present as well as alveolar pattern obliterating the right side cardiac silhouette. Visible caudal pulmonary vessels are in normal limits. The cranial mediastinum are mildly widened and margins are irregular.
Findings
2weeks coughing.
Obesity.
Diffuse bronchial lung pattern – Infectious or non-infectious bronchitis(allergic, eosinophilic, parasitic)
Right middle lung lobe – Pneumonia, Consolidation or collapse.
Midly Widened Mediastinum – fat accumulation or rotated body?
Cardiomegaly – HCM or DCM(unlikely) without accompanying Edema,Pleural effusion and hepatomgaly and etc.
TTW.BAL and US are Recommended
I have a question. In this case, it is hard to tell atelctasia from consoliation without mediastinal shift. Can I say that based on the observation of the left lateral view? Hope someone or Dr.Z to reveal answers!
Allison Zwingenberger says
There is a little bit of mediastinal shift on the dorsoventral projection that supports atelectasis. On the left lateral, there is a small, triangular region of increased opacity in the right middle lung lobe. This suggests atelectasis because it is not very dense and also not very large.

Oh.. I get it and appreciate your help once again!
