摘要

66岁男性，病理证实为胃黏膜相关淋巴组织（MALT）淋巴瘤，行68ga - pentxafor和18F-FDG PET/CT检查。18F-FDG PET/CT显示胃病变处FDG摄取强烈，而68ga - pentxapet /CT显示示踪剂摄取极少。随后的组织病理学检查证实为侵袭性弥漫性大b细胞淋巴瘤（DLBCL）。本病例强调了识别非典型影像学模式以识别组织学转变和指导及时临床干预的重要性。

18F-FDG PET/CT and 68Ga-Pentixafor PET/CT Findings of Gastric Mucosa-associated Lymphoid Tissue Lymphoma Transformation to Diffuse Large B-cell Lymphoma.

A 66-year-old man with a pathology-confirmed gastric mucosa-associated lymphoid tissue (MALT) lymphoma underwent imaging with both 68Ga-pentixafor and 18F-FDG PET/CT. The 18F-FDG PET/CT demonstrated intense FDG uptake in the gastric lesion, whereas the 68Ga-pentixafor PET/CT showed only minimal tracer uptake. Subsequent histopathologic evaluation confirmed a transformation into aggressive diffuse large B-cell lymphoma (DLBCL). This case underscores the importance of recognizing atypical imaging patterns to identify histologic transformation and guide timely clinical intervention.
