Pancreatolithiasis in a Dog with Chronic Pancreatitis

Pancreatolithiasis in dogs is a rare clinical condition with an undetermined etiology.This paper details the case of a 14-year-old dog with a history of subclinical chronic pancreatitis.The dog underwent radiographic, ultrasonographic, and computed tomography (CT) examinations, which confirmed the recurrence of a mammary gland tumor.Radiographs indicated hepatomegaly, bilateral nephroliths, and a solitary, well-defined, mineralized opacity in the right mid-abdomen.Abdominal ultrasonography revealed a 6 mm-sized anechoic area containing a 3 mm hyperechoic structure with acoustic shadowing in the right limb of the pancreatic parenchyma.Although no related clinical signs with the pancreatic stone, but CT scan was performed to clearly determine the exact location of the stone and its relationship with the surrounding structures.An abdominal CT scan confirmed the presence of a pancreatolith, a hyperdense structure, within a hypodense area suspected of being a dilated pancreatic duct in the right limb of the pancreas.A thorough ultrasound evaluation of the pancreatic parenchyma and ducts for pancreatolithiasis is imperative.A CT examination is recommended because of its superior sensitivity and specificity in detecting pancreatolithiasis.
