Figure 1: 18F-fluorodeoxyglucose-positron emission tomography/computed tomography shows mild fluorodeoxyglucose uptake in the mediastinum in the left chest region (a). Axial views of contrast-enhanced computed tomography, 18F-fluorodeoxyglucose-positron emission tomography and fused 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (b-g) show a well-defined, lobulated, heterogeneously enhancing, fluorodeoxyglucose-avid (maximum standardized uptake values-4.3) mass in the left posterior mediastinum, measuring approximately 5.8 cm × 4.9 cm × 5.9 cm in size. The mass was extending into the spinal canal (b-d; arrow) at the level of D1/D2 intervertebral foramen; however, fat planes with the spinal cord were preserved. The lesion was also closely abutting the left subclavian artery with preserved fat planes (e-g; arrow)
