A 77-year-old male patient, until recently a heavy smoker, was hospitalized complaining of dysphagia and emaciation for the past month. He had neither fever nor chest pain upon admission but a recurrent cough with white sputum and progressive dyspnea gradually developed. A chest radiography revealed right upper lung infiltrates and pulmonary atelectasis in the right middle lobe. A thoracic CT scan was requested for further evaluation.
