We report necropsy findings in a captive 60-year-old female greater flamingo (Phoenicopterus roseus) that died suddenly following rupture of a pulmonary artery aneurysm. Histologically, there was focally extensive, intramural granulomatous inflammation with intralesional fungal hyphae, and adjacent severe mixed-cell inflammation and acute haemorrhage at the rupture site. Aspergillus fumigatus was identified as the aetiological agent following DNA PCR amplification and sequencing from paraffin-embedded pulmonary artery tissue sections. The most likely explanation is that this lesion was a consequence of haematogenous spread, secondary to mycotic pneumonia or aerosacculitis, following aspiration of A. fumigatus conidiospores. However, no further fungal-related lesions were observed on gross or histopathological examination.
