A 54-Year-Old Man with Right Opaque Hemithorax and Worsening Shortness of Breath

impaired/dull note was appreciated on the right side of the chest. The skin over the right hemithorax was warm and hard to touch. On abdominal examination, there was massive, palpable hepatomegaly which was tender. The remaining examination was unremarkable. Chest X-ray ( fig. 1 ) disclosed an almost complete opacification of the right hemithorax with the mediastinal silhouette being slightly displaced towards the left side. A CT scan ( fig. 2 ) of the chest showed lobular pleural and parenchymal masses in the right lung, and right hilar and mediastinal adenopathy with a few scattered air bronchograms. Ultrasound of the abdomen revealed an enlarged liver with two mass lesions with sizes of 2–2.4 and 1.7–2 cm. What is your diagnosis? Case Report
