Abstract

Tumors of the oviducts are commonly observed in budgerigars (Melopsittacus undulatus) and cockatiels (Nymphicus hollandicus). However, tumors are infrequently reported in passerine birds; based on the literature search, there are no case reports of tumors of the oviducts. Reports of right oviductal-derived tumors are limited, with adenomas reported only in cockatiels. A 3-year, 6-month-old female Java sparrow (Lonchura oryzivora) was presented for evaluation due to coelomic distension. Contrast imaging revealed left displacement of the intestines. Coelomic ultrasonography identified a 28.3 × 22.6 × 20.2 mm solid mass with multilocular cysts on the right side of the abdomen, indicating a mass likely originating from the right oviduct. Successful excision of the right oviduct was performed utilizing a ventral right paramedian inverted L-shaped incision. The mass extended from the infundibulum to the magnum of the right oviduct. Histopathological examination of the excised tissue confirmed a cystic adenoma of the right oviduct. This case represents the first report of a right oviduct tumor in a Java sparrow.
