Cu-64-DOTATATE Uptake in a Pulmonary Hamartoma

摘要

DOTATATE PET/CT is frequently used to evaluate indeterminant pulmonary nodules suspected to be pulmonary carcinoid. We report an unexpected case of pulmonary hamartoma demonstrating Cu-64-DOTATATE uptake in a 43-year-old woman with a slowly enlarging pulmonary nodule. Histopathological staining showed somatostatin receptor 2 expression on vascular endothelial cells and a proportion of cartilage and smooth muscle cells within the hamartoma.
