Abstract

Adenoid cystic carcinoma (ACC) is a rare and slow-growing tumor, originating from salivary glands. Locoregional recurrence and distant metastasis of ACC can be visualized not only with 18F-FDG but also with 68Ga-PSMA PET/CT due to its high prostate-specific membrane antigen (PSMA) expression. We report 2 cases of metastatic ACC who underwent first 18F-FDG and then 68Ga-PSMA for staging and restaging.

摘要

腺样囊性癌（ACC）是一种罕见且生长缓慢的肿瘤，起源于唾液腺。由于其高前列腺特异性膜抗原（PSMA）表达，18F-FDG 和 68Ga-PSMA PET/CT 不仅可以观察到 ACC 的局部区域复发和远处转移。我们报告了 2 例转移性 ACC 患者，他们先进行 18F-FDG 后进行 68Ga-PSMA 分期和再分期。
