Abstract

Intravascular large B-cell lymphoma is a rare subtype of extranodal invasive non-Hodgkin lymphoma, and the diagnosis is challenging. Here we report findings of 18 F-FDG PET/CT study in a case of intravascular large B-cell lymphoma invading bilateral lungs and kidneys in a 63-year-old woman. The PET/CT images showed diffuse increased FDG uptake in bilateral lungs and kidneys. Unexpectedly, there was no abnormal density on the CT images. The 18 F-FDG PET/CT seems to be valuable and sensitive in the diagnosis of intravascular large B-cell lymphoma.

摘要

血管内大 B 细胞淋巴瘤是一种罕见的结外侵袭性非霍奇金淋巴瘤亚型，诊断具有挑战性。在此，我们报告一例 63 岁女性血管内大 B 细胞淋巴瘤侵犯双肺和双肾的 18 F-FDG PET/CT 研究结果。PET/CT 图像显示双肺和双肾弥漫性 FDG 摄取增加。出乎意料的是，CT 图像上没有异常密度。18 F-FDG PET/CT 似乎对血管内大 B 细胞淋巴瘤的诊断具有重要价值和敏感性。
