We report herein computed tomography and F-fluoro-2-deoxyglucose positron emission tomography findings of primary pulmonary follicular dendritic cell sarcoma in a 51-year-old man, which is an extremely rare malignancy originating from follicular dendritic cells. Computed tomography scan revealed a 2.4-cm, well-defined solitary pulmonary nodule with delayed contrast enhancement but without regional lymphadenopathy, distant metastasis, or calcification within the nodule. On F-fluoro-2-deoxyglucose positron emission tomography scan, this nodule showed moderate hypermetabolic activity with a maximum standardized uptake value of 3.2.
我们在此报告一例 51 岁男性原发性肺滤泡树突状细胞肉瘤的计算机断层扫描和 F-氟代-2-脱氧葡萄糖正电子发射断层扫描表现，这是一种源自滤泡树突状细胞的极其罕见的恶性肿瘤。计算机断层扫描显示 2.4 厘米大小、边界清楚的孤立性肺结节，增强后延迟扫描可见强化，但结节内无区域性淋巴结病、远处转移或钙化。F-氟代-2-脱氧葡萄糖正电子发射断层扫描显示该结节呈中度高代谢活性，最大标准化摄取值为 3.2。
