Solitary pancreatic metastasis is a rare cause of pancreatic neoplasm. Pancreatic ductal adenocarcinoma is the primary differential consideration when a solitary pancreatic mass is diagnosed, as it is the most common solitary solid pancreatic neoplasm. A majority of pancreatic ductal adenocarcinomas arise in the region of the head of the pancreas; however, specific neoplastic and non-neoplastic lesions can occur at or adjacent to the pancreatic head, which can mimic a pancreatic ductal adenocarcinoma. Therefore, a histopathological diagnosis is essential for confirming pancreatic ductal adenocarcinoma. Isolated solitary metastasis from primary lung adenocarcinoma is a rare cause of a solitary pancreatic head mass. We report a case in which imaging and pathology were integral to the diagnosis of a solitary lung adenocarcinoma metastasis to the head of the pancreas, which ultimately guided appropriate patient management.
孤立性胰腺转移瘤是胰腺肿瘤的罕见病因。当诊断出孤立性胰腺肿块时，胰腺导管腺癌是主要的鉴别诊断对象，因为它是最常见的孤立性实性胰腺肿瘤。大多数胰腺导管腺癌发生在胰头区域；然而，特定的肿瘤性和非肿瘤性病变可发生在胰头或其附近，可能会酷似胰腺导管腺癌。因此，组织病理学诊断对于确诊胰腺导管腺癌至关重要。原发性肺腺癌的孤立性转移是孤立性胰头肿块的罕见病因。我们报告一例病例，其中影像学和病理学对于诊断孤立性肺腺癌转移至胰头至关重要，最终指导了对患者的恰当管理。
