A 79-year-old man anteriorly treated for primary central nervous system diffuse large B-cell lymphoma with MRI complete response after immunochemotherapy was referred 1 year later for 18FDG PET/CT because of right persistent lombosciatic radicular pain for 6 months with negative medullary and spine MRI and negative cerebrospinal fluid cytology. Linearly intense uptake was observed in several roots of lumbosacral plexus, highly suggestive of peripheral neurolymphomatosis relapse. No specific treatment was engaged because of rapid decrease of performance status leading to death.
一位 79 岁男性，先前因原发性中枢神经系统弥漫性大 B 细胞淋巴瘤接受了免疫化疗，治疗后 MRI 完全缓解。1 年后，因持续 6 个月的右侧腰骶神经根痛而就诊，脊髓和脊柱 MRI 及脑脊液细胞学检查均为阴性。18FDG PET/CT 显示腰骶丛多个神经根线性摄取增强，强烈提示外周神经淋巴组织肿瘤复发。由于患者的功能状态迅速下降导致死亡，因此未进行特定治疗。
