Abstract:

Multiple primary tumors (MPT) are cases describing no similar histopathology between two or more primary tumors. This paper introduces one case with gastric, liver, and pancreatic lesions found by physical examination; the MPT was indicated by energy spectrum CT enhancement examination; the patient was finally pathologically confirmed with gastric stromal tumor, intrahepatic cholangiocarcinoma, and pancreatic intraductal mucinous papillary tumor, which was a clinically rare process. For MPT, it is easy to be misdiagnosed as metastasis clinically. This paper provides references for its clinical diagnosis and treatment.

Key words:

Gastric stromal tumor, Intrahepatic cholangiocarcinoma, Pancreatic intraductal papillary mucinous tumor, Multiple primary tumors, Energy spectrum CT

摘要：

多原发肿瘤（multiple primary tumors，MPT）是指两个或多个原发肿瘤之间无相似组织病理学的病例。本文介绍1例因查体发现胃、肝脏及胰腺病变患者，通过完善能谱CT增强检查提示MPT，最后病理证实为胃间质瘤、肝内胆管细胞癌、胰腺导管内黏液性乳头状肿瘤，临床罕见。对于MPT，临床易误诊为转移瘤，希望本文能为临床诊断及治疗提供参考。
