Figure 3. Axial and coronal views of the CT thorax with contrast obtained on presentation. Panel A shows the axial section of the thorax and visualization of the heterogeneous composition of the posterior left upper lobe mass while visualized in the abdominal window. Panel B shows the same image as panel A, but in the bone window. Panel C shows the CT thorax findings in the coronal view and abdominal window. Panel D shows the same image as panel C, but in the bone window. Thick black arrows in all panels point to the necrotic left apical mass. Blue stars in panels C and D indicate the left pleural effusion that was visualized. Additionally, a moderate pleural effusion was noted in the right lung field. CT – computed tomography.
