Abstract: Lateral body wall herniation with involvement of the oviduct was diagnosed in a female nanday conure (Aratinga nenday) and a female eclectus parrot (Eclectus roratus). A history of chronic egg laying and chronic reproductive activity was reported in both cases. A subcutaneous mass in the area of the caudal left lateral body wall was present in both birds. Diagnostic imaging (ultrasonography, computed tomography) and cytologic examination lead to the diagnosis of left lateral body wall herniation with involvement of the oviduct. In the conure, a developing egg was contained within the herniated oviduct. Both cases were successfully treated by salpingohysterectomy and surgical correction of the hernal ring. Lateral body wall herniation with oviductal involvement in birds has not previously been reported and should be considered as a differential for birds presenting with masses originating from the lateral body wall.
