PET-CT reported FDG avid lymph nodes with the biggest measuring 68 x 55 x 29 mm (SuvMax: 19) and 85 x 150 x 95 mm (SuvMax: 28) in the left supraclavicular region extending to the anterior mediastinum (Figure 1).

On the postoperative second day, a lymphatic fistula was observed with an output up to 1400 ml daily (Figure 2(a)). Although documented daily output was fairly decreased, the fistula persisted (Figure 2(b)).

The fistula site and closure were then confirmed with CT (Figure 3). The fistula closed within two days after the intervention and in due time etoposide and cisplatin-based chemotherapy was initiated for thymic carcinoma diagnosis.
