Chronic Cough With Non-Resolving Mass-like Consolidation

      Case Presentation

      A 72-year-old Chinese man presented with a 5-month history of chronic dry cough, weight loss, and progressive dyspnea. There was no associated hemoptysis, hoarseness, epistaxis, or fever on systemic review. He was a nonsmoker and had no family history of malignancy. He was treated for pulmonary TB 40 years ago. A chest radiograph (Fig 1) showed mass-like consolidation in the right midzone with loss of the right hilar border, a small right pleural effusion, and bi-apical scarring. On physical examination, he was afebrile and normotensive, and he had pulse oxygen saturation of 97%. Examination of the chest was remarkable only for reduced breath sounds over the right chest. He did not have digital clubbing, distended neck veins, or cervical lymphadenopathy.
