55-year-old man who consults for dysphonia. In the anamnesis he refers to a month of asthenia and unquantified weight loss. Chest X-ray shows increased density in the left upper lobe and occupation of the aortopulmonary window. Bronchoscopy shows paralysis of the left vocal cord, without endoscopic image suggestive of neoplasia. What is the most likely diagnosis?
The most frequent cause of recurrent nerve palsy is bronchopulmonary carcinoma. The fact that it is not accessible to endoscopic vision does not mean that it is not there.
