Ultrasound Features of Pancreatic Torsion in a Young Dog

A 7-month-old male neutered Labrador Retriever was referred for vomiting, inappetence, and lethargy. Baseline bloodwork revealed mild mature neutrophilia, elevated amylase and lipase, and mild hypochloremia. Abdominal ultrasound showed a cavitated left cranial abdominal mass with a "whirl sign," indicating a torsed organ. Surgical resection and histopathology confirmed pancreatic torsion, a rare disease in young dogs. The patient recovered uneventfully and was discharged the following day. This is the first report describing a "whirl sign" on ultrasound associated with pancreatic torsion in a dog.
