A 43-year-old woman presented with recent onset of a nonproductive cough associated with a low-grade fever for 4 months. A chest radiograph revealed a left lower-lobe infiltrate and a raised left hemidiaphragm. She was treated with antibiotics for presumed pneumonia. However, she subsequently experienced left-sided chest pain and had hemoptysis. Chest computed tomography was done and the relevant cut is shown (Fig. 1). What is your differential diagnosis, and what investigations or treatment would you offer?
