Abdominal pedunculated accessory liver lobe in a dog.

Pedunculated accessory liver lobes are rare hepatic anomalies requiring imaging differentiation from neoplasia.

This case report describes an unusual anatomical finding of an abdominal pedunculated accessory liver lobe in a canine patient. Accessory liver lobes are rare hepatic anomalies in dogs, characterized by ectopic hepatic tissue connected to the main liver by a vascular pedicle. The case presents the clinical presentation, diagnostic findings, and management of this condition. Imaging studies, likely including ultrasound and/or CT, were utilized to characterize the lesion and differentiate it from other intra-abdominal masses. The pedunculated nature of this accessory lobe creates potential complications including volvulus, torsion, or hemorrhage. The authors discuss the clinical significance of recognizing this condition and its differential diagnosis from neoplastic processes. This case contributes to the limited veterinary literature on hepatic developmental anomalies and emphasizes the importance of thorough abdominal imaging in dogs presenting with abdominal abnormalities. The findings provide valuable insights for veterinary surgeons and internists regarding hepatic anatomy variations and their potential clinical implications in small animal practice.
