两只韩国短毛猫出现便秘和呕吐症状。计算机断层扫描显示病例1结肠肿块伴有钙化和淋巴结转移，病例2小肠肿块有播散性腹膜转移和钙化。组织病理学检查显示肠腺癌伴有骨化生变。病例1手术后两个月死于远处转移；病例2在诊断后五个月未见有转移，但表现食欲不振，七个月后安乐死。钙化影像学上应考虑转移性肠腺癌伴有骨化生变作为鉴别诊断，诊断时淋巴结转移可能预示着差预后。© 2023 The Korean Society of Veterinary Science.

Two Domestic Korean Shorthair cats presented with dyschezia and vomiting. Computed tomography revealed a colonic mass with calcification and lymph node metastasis in case 1, and a small intestinal mass with disseminated mesenteric metastasis and calcification in case 2. Histopathology revealed intestinal adenocarcinoma with osseous metaplasia. Case 1 died two months after surgery from distant metastasis; and case 2 showed no metastasis for five months but presented with anorexia, euthanized seven months after diagnosis. Metastatic intestinal adenocarcinoma with bone formation should be considered as differential diagnosis for calcification on imaging, and lymph node metastasis at diagnosis may indicate poor prognosis.© 2023 The Korean Society of Veterinary Science.
