An adult Green Java peafowl, from a private aviary, was presented for treatment at the Riphah Pet Hospital, Lahore, Pakistan. Physical examination of the bird revealed lethargy, gasping and head jerking but no other clinical signs. The bird died before any intervention. At necropsy, multiple off-white hard nodules were observed in the lungs and two off-white flat growths in abdominal air sacs. Systemic spread of the fungus to the liver causing hepatitis was also noticed. Kidneys were pale, yellow and atrophied but fungus hyphae or conidia could not be detected in kidneys. Microscopically, the lung nodules were typical granulomas consisting of Aspergillus spp. hyphae and necrosis in the centre surrounded by inflammatory cells, mainly heterophils and macrophages and rare multinucleated giant cells. From the literature search, it appears to be the first report of angioinvasive mycotic pneumonia in Green Java peafowl.
