Invasive intrasanal fibrosarcoma and secondary colienteritis in an budgerigar (Melopsittacus undulatus)

Abstract

Budgerigars(Melopsittacus undulatus) are small parrots, widely bred in captivity and, therefore, become susceptible to numerous diseases.Thus, we aimed to describe an unusual occurrence of intranasal fibrosarcoma associated with secondary bacterial enteritis in a domestic budgerigar. At the clinical examination, the psittacinebirdpresented lateral deformity of the beak associated with a mass in the region of wax ́s beak, anorexia and apathy and respiratory complications died. At necropsy, various organs were collected for histopathology and,additionally, for collecting swab clocal and some organs for microbiological isolation and antimicrobial susceptibility profile. The bacterial finding determined the presence of ampicillin resistant Escherichiacoliand the sulfonamide group antibiotics. At necropsy, dehydration and enophthalmia, enteritis, abundant adipose tissue were observed in the coelomatous cavity, and the cutting mass was endophytic and irregularHistologically, a neoplastic proliferation in the nasal plane of the bone was cross-cut and compatible with the characterization of a fibrosarcoma. Therefore, the importance of an early and differential diagnosis for immediate therapeutic interventions, especially those of the unusual occurrence such as invasive intranasal fibrosarcoma, which can lead to death, is emphasized.
