Key result
18F-FDG PET/CT successfully identified pericardial noduli and irregular tissue, leading to a diagnosis of epithelioid mesothelioma as the cause of constrictive pericarditis.
Case Report (n=1)
18F-FDG PET/CT is a valuable imaging modality for identifying rare malignant causes of constrictive pericarditis, such as primary pericardial mesothelioma.
May identify occult pericardial mesothelioma on FDG PET/CT; leaves open routine use in constrictive pericarditis.
A 57-year-old man presented with shortness of breath and ankle edema. Constrictive pericarditis with an unexplained mass surrounding the heart was diagnosed by ultrasound. Accordingly, F-FDG PET/CT was performed. Multiple PET-positive noduli and irregular tissue were located in the pericardium, with pleural fluid present, but without additional pulmonic or pleural pathology. A pericardiectomy was successfully performed. Histopathology and immunohistochemical staining revealed epithelioid mesothelioma.

Edel et al. (2018) conducted a case report in Constrictive pericarditis and malignant mesothelioma (n=1). 18F-FDG PET/CT was evaluated. 18F-FDG PET/CT successfully identified pericardial noduli and irregular tissue, leading to a diagnosis of epithelioid mesothelioma as the cause of constrictive pericarditis.
