1. Lung: Fibrosis, pleural and interstitial, multifocal, 

 moderate, with mild multifocal chronic pneumonia, Atlantic 

 bottlenose dolphin ( Tursiops truncatus ), cetacean. 



2. Lung: Necrogranulomas, chronic, multifocal, moderate, with 

 mineralization. 



3. Lung: Congestion and edema, multifocal, moderate, with 

 alveolar histiocytosis. 



4. Liver: Congestion, centri lobular, diffuse, mild. 



5. Liver: Fibrosis, portal and capsular, diffuse, mild. 



6. Lymph nodes: Lymphadenitis, eosinophilic, necrotizing, 

 multifocal, mild, with multinucleated giant cells. 



7. Lymph node: Lymphoid hyperplasia, multifocal, moderate. 



8. Lymph node: Lymphoid depletion, multifocal, moderate. 



Comment: The cause of death is not clear. The most significant lesions were 

 pulmonary. The pulmonary fibrosis probably represents the resolution phase of a 

 pneumonia; the cause was not evident. The pulmonary necrogranulomas were probably 

 caused by parasites. The pulmonary congestion and edema could have agonal or 

 caused by drowning. The hepatic congestion was probably caused by terminal 

 cardiovascular collapse. Similar eosinophilic necrotizing lymphadenitis with 

 multinucleated giant cells has been seen in other dolphins; the cause is unknown. 

 Both hyperplastic and depleted lymph nodes were present.
