Abstract

Diffuse involvement of pancreatic neuroendocrine tumor (PNET) is a rare presentation. Here, we report a case of suspected autoimmune pancreatitis with 18 F-FDG and 18 F-FAPI-42 PET/CT showing increased tracer uptake in the entire pancreas, which was eventually confirmed by biopsy pathologic analysis as diffuse PNET. 18 F-AlF-NOTA-octreotide PET/CT imaging showed heterogeneous tracer uptake in the entire pancreas.

摘要

胰腺神经内分泌肿瘤（PNET）弥漫性累及较为罕见。本文报道 1 例疑似自身免疫性胰腺炎患者，18 F-FDG 和 18 F-FAPI-42 PET/CT 示胰腺整体摄取增加，最终经活检病理分析证实为弥漫性 PNET。18 F-AlF-NOTA-octreotide PET/CT 显像示胰腺整体呈异质性摄取。
