Figure 4. (a, b) CT obtained 3 months after total tumour excision shows a smaller contrast enhancing mass of soft tissue attenuation without remarkable cystic component at the same location as the original tumour. Biopsy from this mass revealed tumour recurrence. (c) Post contrast T1 weighted, (b) T2 weighted axial, and (e) pre-contrast T1 weighted sagittal images obtained within few days as the CT in (a, b) demonstrate the recurrent contrast enhancing anterior mediastinal tumour.
