18F-FDG PET/CT can identify malignant pericardial thickening, such as mucinous adenocarcinoma.
Supports FDG PET/CT detection of rare pericardial malignancies in select cases; leaves open routine use pending larger studies.
A 56-year-old woman presented a history of left chest discomfort for 6 months. A prior CT revealed pericardial thickening, and malignancy cannot be excluded. For this reason, an FDG PET/CT scan was performed, which revealed abnormal activity inside the pericardium. The pathologic examination results after surgery demonstrated a mucinous adenocarcinoma.
