胰腺肝样腺癌是一种罕见的侵袭性肿瘤，预后较差。我们描述了一例胰腺肝样腺癌的增强 CT 和 FDG PET/CT 结果，其甲胎蛋白水平显着升高，表现为急性胰腺炎。原发性胰腺肿瘤弥漫性累及胰腺，增强CT显示类似急性坏死性胰腺炎的不均匀强化。 FDG PET/CT 显示左侧锁骨上和腹膜后淋巴结转移灶有强烈的 FDG 摄取（SUVmax，24.5），表明 FDG PET/CT 可能有助于对这种侵袭性肿瘤进行分期。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。

Hepatoid adenocarcinoma of the pancreas is a rare aggressive tumor with poor prognosis. We describe contrast-enhanced CT and FDG PET/CT findings in a case of pancreatic hepatoid adenocarcinoma with significantly elevated α-fetoprotein level presenting as acute pancreatitis. The primary pancreatic tumor diffusely involved the pancreas and showed heterogeneous enhancement mimicking acute necrotizing pancreatitis on contrast-enhanced CT. FDG PET/CT showed intense FDG uptake (SUVmax, 24.5) of the left supraclavicular and retroperitoneal lymph node metastases, suggesting FDG PET/CT may be useful for staging of this aggressive tumor.Copyright © 2024 Wolters Kluwer Health, Inc.
