Isolated gall bladder torsion in a juvenile greyhound dog

An 11-month-old, entire, male greyhound dog was presented with a 2-day history of vomiting, lethargy and abdominal pain. An abdominal ultrasound and a computed tomography study were performed revealing images compatible with isolated gall bladder torsion. Surgery confirmed a twisted floating gall bladder, and a cholecystectomy was performed. The dog recovered without any complications. Gall bladder torsion is a rare but potentially life-threatening condition in veterinary medicine, and a prompt diagnosis preoperatively is valuable. This is the first reported case of preoperative diagnosis of isolated gall bladder torsion by diagnostic imaging in veterinary medicine.
