An 8-year-old male neutered Korean shorthair cat presented with chronic vomiting. Radiographically, an oval-shaped soft tissue abdominal mass caudoventral to the left kidney was detected. On ultrasonography, the hypoechoic mass was well-defined with thick, irregular, and hyperechoic margins and had no continuity with the pancreas or other adjacent organs. The mass was surgically excised. Areas of atypical pancreatic acinar epithelial cells were identified histopathologically. Postoperative CT demonstrated a normal pancreas in the expected anatomical region. Based on diagnostic imaging, surgical and histopathology findings, the mass was diagnosed as a well-differentiated pancreatic acinar cell adenocarcinoma arising from ectopic pancreatic tissue.
