  • Figure 1
    Posteroanterior chest radiography

    Posteroanterior chest radiography which shows a well-defined nodule located in upper right lobe (black arrow).

     
    Area of Interest: Lung; Imaging Technique: Digital radiography; Procedure: Diagnostic procedure; Special Focus: Acute;
     
     
  • Figure 2
    Thorax CT with intravenous contrast
     

    Coronal scan which confirmed the existence of a well-defined pulmonary nodule, located in the upper right lobe. It was associated with an air-trapping area in the adjacent pulmonary parenchyma (arrow).

     
    Area of Interest: Lung; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Acute;

    Axial scan confirming the existence of a well-defined pulmonary nodule, located in the upper right lobe. This nodule showed a homogeneous enhancement and was associated with an air-trapping area in the adjacent...

     
    Area of Interest: Lung; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Acute;

    Sagittal scan which confirmed the existence of a well-defined pulmonary nodule, located in the upper right lobe. It was associated with an air-trapping area in the adjacent pulmonary parenchyma (arrow).

     
    Area of Interest: Lung; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Acute;
     
     
  • Figure 3
    Axial scan thorax CT (soft tissue window)

    Axial scan thorax CT with soft tissue window which shows that the nodule had high density in enhanced CT.

     
    Area of Interest: Lung; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Acute;
     
     
  • Figure 4
    Pathological anatomy results

    Pathological anatomy results of the biopsied nodule: H-E staining shows polygonal cells with round-oval, regular and vesicular nucleus. These cells were positive in TTF-1 staining (top left). These findings are...
