摘要

我们报告了一例55岁左颈部转移性鳞状细胞癌患者的18F-FDG和68Ga-FAPI-46 PET/CT检查结果。18F-FDG PET/CT对原发性恶性肿瘤的检测为阴性。68Ga-FAPI PET/CT显示，左侧腭扁桃体放射性示踪剂摄取增加，而右侧腭扁桃体放射性示踪剂摄取低。根据PET/CT结果，患者接受了临床检查和左扁桃体活检。组织学表现为扁桃体鳞状细胞癌。本病例证明了68Ga-FAPI-46 PET/CT在原发不明的肿瘤中定位原发恶性肿瘤的附加价值。

Squamous Cell Carcinoma of the Tonsil Unmasked by 68 Ga-FAPI-46 PET/CT.

We reported 18 F-FDG and 68 Ga-FAPI-46 PET/CT findings in a 55-year-old woman with metastatic squamous cell carcinoma of the left neck. 18 F-FDG PET/CT was negative for the detection of primary malignancy. On 68 Ga-FAPI PET/CT, increased radiotracer uptake was noted in the left palatine tonsil, whereas low background uptake was observed in the right palatine tonsil. Based on the PET/CT findings, the patient underwent clinical examination and biopsy of the left tonsil. Histology demonstrated the presence of a squamous cell carcinoma of the tonsil. The case demonstrated the added value of 68 Ga-FAPI-46 PET/CT for locating the primary malignancy in cancer of unknown primary.
