Findings of intramediastinal gossypiboma with F-18 FDG PET in a melanoma patient.
FDG PET/CT scan was performed to evaluate recurrence in an asymptomatic 64-year-old man with a history of melanoma in the left posterior ear. PET/CT images showed an intense ring-shaped area of FDG activity in the posterior mediastinum in a large posterior mediastinal mass. However, further evaluation indicated that this activity was caused by an intramediastinal gossypiboma after coronary artery bypass graft surgery 4 years before the PET/CT scan.
