Epithelial-myoepithelial carcinoma (EMC) is a rare malignant neoplasm arising most frequently in the salivary glands and exceptionally in the nasal cavity. EMC accounts for ~1–2% of salivary gland tumors. Even if the nodal and distant metastasis rates are low, tumor staging remains indicated. Here, the authors present the 2-deoxy-2-[18F]fluoro-D-glucose PET-CT (18F-FDG-PET/CT) study of a very rare case of biopsy-proven EMC of the left nasal cavity. This 18F-FDG-PET/CT was performed to stage this tumor and guide the therapeutic strategy due to an atypical high-grade presentation in immunohistochemistry. To our knowledge, this is the first case reporting such high 18F-FDG avidity of EMC of the nasal cavity in PET/CT.
