Computer Tomography (CT) Scan Case Study #4
松鼠犬 Pomeranian
-
Pomeranian, Male, 10 years old
-
-
Clinical History:
-
Mass identified in caudal chest for a few years but recently start to cough a lot, coughing situation got better while on medicines but worse again once medicines finished.
-
Findings:
-
There is a moderate alveolar pattern in the left caudal lung lobe and right cranial lung lobe
(craniomedially and caudally). A milder interstitial to alveolar pattern is present in the caudal segment of the left cranial lung lobe. There is partial decreased volume of the left lung lobes.
-
-
There is no evidence of pulmonary nodules or masses.
-
-
There is a soft tissue attenuating mass in the right caudal thorax. This mass is in continuity with the diaphragm. Post-contrast the vasculature of the liver is in continuity with the caudal thoracic mass indicating that the mass represents a herniated liver lobe (likely right liver lobes).
-
-
There are small mineralizations in the renal pelvis and medulla of the right kidney.
-
-
The cardiovascular and mediastinal structures are normal.
-
Conclusion:
-
1. Herniated liver lobe/s.
-
-
2. Multifocal alveolar pattern.
-
-
3. Calculi in the right kidney.
-
-
Differential diagnosis to consider for the multifocal alveolar pattern includes pneumonia, haemorrhage, atelectasis/ fibrosis or less likely neoplasia. Given the history I would consider pneumonia more likely.

*** The above case is for reference only. If you have any questions concerning your pet's condition, please discuss with your veterinarian. ***

 -
Alveolar patter in the left caudal lung lobe.
 -
Herniated liver lobe. Note the continuity of the hepatic vasculature with the mass.
