Abstract

Abstract: A 54-year-old man presented with left lower quadrant pain. CT showed no cause for his pain but identified an incidental 2.0-cm enhancing lesion in the pancreatic tail. On MRI, this lesion was hyperenhancing and diffusion-restricting, suspicious for a neuroendocrine tumor. However, EUS-guided biopsy yielded only benign pancreatic tissue. Due to this discordance, 64 Cu-DOTATATE PET/CT was performed. The pancreatic tail lesion was tracer-avid, suggesting a well-differentiated neuroendocrine tumor. Based on the PET findings, the patient underwent distal pancreatectomy. Surgical pathology revealed only focal chronic pancreatitis with islet aggregation, a previously undescribed mimic of neuroendocrine tumor on DOTATATE PET/CT.

DOTATATE PET/CT 上模仿神经内分泌肿瘤的灶性胰腺炎与放射学和病理学的相关性。

摘要：一名 54 岁的男子因左下腹疼痛就诊。CT 显示他的疼痛没有原因，但在胰腺尾部偶然发现了一个 2.0 厘米的增强病灶。磁共振成像显示，该病灶呈高增强和弥散限制性，怀疑为神经内分泌肿瘤。然而，在 EUS 引导下进行的活检仅发现良性胰腺组织。由于这种不一致，于是进行了64 Cu-DOTATATE PET/CT检查。胰腺尾部病变呈示踪剂avid，提示为分化良好的神经内分泌肿瘤。根据 PET 检查结果，患者接受了胰腺远端切除术。手术病理结果显示仅有局灶性慢性胰腺炎伴胰岛聚集，这是一种以前未在 DOTATATE PET/CT 上描述过的神经内分泌肿瘤。
