A 60-year-old man diagnosed with small cell lung cancer, stage IV, presented an excellent response after first line therapy with chemotherapy (6 cycles of carboplatin + etoposid), with thoracic computed tomography showing a significant shrinking of the left hilar mass, pulmonary nodules, and mediastinal adenopathies (Fig. 1A – before; Fig. 1B – after chemotherapy). As he presented with dysphonia, and paralysis of the left vocal cord (VC) was documented with videolaryngoscopy, left recurrent laryngeal nerve (RLN) involvement by lung carcinoma was assumed. To evaluate residual neoplastic disease and consider consolidative thoracic radiotherapy, a positron emission tomography-computed tomography (PET-CT) scan was performed showing residual metabolic activity in mediastinal adenopathies, but also asymmetric hypermetabolism in the right VC (Fig. 1C-1D). Laryngoscopy was repeated and no macroscopic changes nor histopathological signs of neoplastic involvement were found in the right VC.
