A 44-year-old male nonsmoker presented to the respiratory department with progressive left chest pain for 20 days. He had previously been healthy with normal immunity. He had no cough, fever, breathlessness, or sputum production. Physical examination revealed local tenderness on the left 10th posterior rib.
