双肺多发结节性淀粉样变18F-FDG PET/CT显像一例

笔者报道了1例行18F-氟脱氧葡萄糖（FDG）PET/CT显像的双肺多发结节性淀粉样变病例，分别从临床症状、影像学表现及病理诊断等方面分析了该病的特点，并通过文献复习加深了对肺淀粉样变的认知。结节性肺淀粉样变的发病率低，临床症状不典型，与常见的肺内肿瘤鉴别困难，临床鉴别肺结节时应考虑该病的可能。因此，18F-FDG PET/CT显像对双肺多发结节性淀粉样变病变范围的评估至关重要。

18F-FDG PET/CT imaging of double lung multiple nodular amyloidosis: a case report

A case of double lung multiple nodular amyloidosis with 18F-fluorodeoxyglucose (FDG) PET/CT imaging was reported. The characteristics of the disease were analyzed from clinical symptoms, imaging manifestations and pathological diagnosis. The understanding of pulmonary amyloidosis was deepened through literature review. The incidence of pulmonary nodular amyloidosis is low, the clinical symptoms are atypical, and it is difficult to differentiate from common lung tumors. It is suggested that the possibility of pulmonary nodular amyloidosis should be considered in the differential diagnosis of pulmonary nodules. Therefore, 18F-FDG PET/CT imaging is very important to evaluate the extent of double lung multiple nodular amyloidosis.
