Fluorodeoxyglucose positron emission tomography/computed tomography identifying pericardial metastasis from early‐stage p16‐positive oropharyngeal cancer

Pericardial metastasis from HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) without local recurrence is extremely rare. We report about a 69-year-old man exhibiting pericardial metastasis on positron emission tomography/computed tomography (PET/CT). There are currently no reports on the use of PET/CT in patients with pericardial metastasis from p16-positive OPSCCs.
