Gallbladder Rupture in an Adult Weimaraner Dog.

A 6-year-old spayed female Weimaraner weighing 47 kg was referred to the University Veterinary Hospital with suspected acute gastric dilatation and volvulus (GDV). Radiographic examination did not confirm GDV, but a mild peritoneal effusion was diagnosed. Abdominal ultrasound confirmed the diagnosis of peritoneal effusion, but the cause of these changes was not clarified. An increase in leukocytosis and a worsening of the clinical condition were quickly noted. It was decided to perform a CT scan, and localized ileus, gallstones, and the gallbladder showed marked irregular contours and thickening, with suspected rupture as the cause of the peritonitis. A laparotomy confirmed the diagnosis, and surgical treatment was performed.
