Ultrasonographic and radiographic assessment of concurrent periumbilical and pericloacal hernias in an Atlantic canary ( Serinus canaria )

Abstract Coelomic hernias are uncommon in small passerines. A 2‐year‐old female Atlantic canary ( Serinus canaria ) presented with two ventral swellings consistent with concurrent coelomic hernias: a periumbilical lesion (1.2 × 1.0 × 0.5 cm) and a pericloacal lesion (0.8 × 0.5 × 0.2 cm). Both were soft, non‐painful and associated with mild skin discoloration. Survey radiography (right lateral and ventrodorsal views) and high‐frequency ultrasonography (8–12 MHz linear transducer) demonstrated herniation of intestinal loops and mesenteric fat, with no imaging evidence of coelomic effusion or a discrete mass lesion. Because the bird was clinically stable and there were no signs of incarceration or necrosis, conservative management was recommended. To our knowledge, this is the first report of concurrent periumbilical and pericloacal coelomic hernias in a canary. This case highlights the value of combining radiography and ultrasonography when evaluating ventral abdominal swellings in small passerines and supports conservative management in stable, uncomplicated cases.
