ABSTRACT
ABSTRACT: Adenoid cystic carcinoma (ACC) is a rare cancer that arises from salivary glands and other secretory glands. Pulmonary metastases are frequently observed in ACC patients with metastatic disease. Previous research showed that ACC often shows high PSMA uptake on 68Ga-PSMA-11 PET/CT. Here, we present PET images from an ACC patient with pulmonal, pleural metastases, and malignant pleural effusion, with comparable tracer uptake on 68Ga-PSMA-11 PET and 18F-FDG PET.

Adenoid cystic carcinoma is a rare cancer that arises from secretory glands. Metastases are mainly seen in the lungs and bones. Cardiac metastases are extremely rare; only 1 case has previously been described. In this patient, cardiac metastases were suspected based on CT imaging. Tumor imaging by Ga-prostate-specific membrane antigen (PSMA)-11 PET is mainly used in prostate cancer patients but is also of interest in adenoid cystic carcinoma patients because of high PSMA-ligand uptake in salivary glands. Ga-PSMA-11 PET imaging supported the suspicion of cardiac metastases, because the cardiac lesions showed similar tracer uptake compared with other metastases.
