False-positive thyroid cancer metastasis on whole-body radioiodine scanning due to retained radioactivity in the oesophagus
In patients with differentiated thyroid cancer, radioiodine uptake in the mediastinal area most often indicates thyroid cancer metastasis. We review 15 radioiodine whole-body scans showing 19 mediastinal artef...
