Abstract
Thyroid adenocarcinoma was diagnosed in an adult bald eagle (Haliaeetus leukocephalus) with clinical signs of weakness manifested by inability to fly. Physical examination at the time of admission revealed dried blood in the pharynx and glottis and the presence of pharyngeal trichomonads. Radiographs revealed a large soft tissue mass in the area of the left coracoid and clavicular bones. One month following successful treatment for trichomoniasis, the bird suffered an acute episode of tracheal hemorrhage and died. Necropsy revealed a large mass within the interclavicular air sac. The histologic features were consistent with thyroid adenocarcinoma. This is the first report of thyroid neoplasia in a member of the order Falconiformes.
