Lipid pneumonia is an unusual, non-infectious, inflammatory lung disease characterized by patchy pneumonic consolidation secondary to accumulation of lipid in macrophages. It can be classified as exogenous or endogenous, depending on whether it is associated with the aspiration of foreign material. Endogenous lipid pneumonia (EnLP) has been reported in many mammal species. In pet birds, EnLP is an incidental and uncommon lesion of unknown pathogenesis. A 35-year-old African grey parrot (Psittacus erithacus erithacus) was presented for depression lasting several months, with marked worsening over the 2 days prior to presentation. The animal died shortly after admission. Necropsy examination showed that the lungs were firm with diffuse grey discolouration. Microscopically, there was EnLP, anthracosis, severe atherosclerosis and hepatic amyloidosis. Although the pathogenesis of EnLP in birds is not clear, it has been associated with concurrent atherosclerosis, hepatic diseases and other lesions of the respiratory tract. This is the first description of EnLP in a bird associated with severe respiratory distress.
