Abstract

Franciscanas Pontoporia blainvillei are small dolphins endemic to Brazil, Uruguay and Argentina. During routine pathologic examinations, chronic pneumonia associated with cholesterol deposits was found in 16.7% of stranded and incidentally bycaught franciscanas (n = 60), and was more frequent in dolphins from the Brazilian state of São Paulo (Franciscana Management Area II) and frequently accompanied by splenic lymphoid hyperplasia. It is unclear why these otherwise uncommon lesions were relatively frequent in the studied dolphins, and further research is advised.
