Case report: Thoracic schwannoma as a diagnostic pitfall in both 18F-Choline PET/CT and 18F-FDG PET/CT

We report increased 18 F-FDG uptake in the right posterior mediastinal region in a 70-year-old woman following the discovery of a mass in the aftermath of a bronchitis episode. We also report increased 18 F-Choline uptake in the right posterior mediastinal region in a 66-year-old man with newly disc...

Summary:We report increased 18 F-FDG uptake in the right posterior mediastinal region in a 70-year-old woman following the discovery of a mass in the aftermath of a bronchitis episode. We also report increased 18 F-Choline uptake in the right posterior mediastinal region in a 66-year-old man with newly discovered prostate cancer, which may indicate the presence of mediastinal metastases. Both patients had a thoracic MRI showing an intense gadolinium enhancement in the same region, consistent with thoracic schwannomas, which were subsequently proven histologically. This case highlights that schwannoma is a diagnostic pitfall in both 18 F-FDG and 18 F-Choline PET/CT.
