Patient
female, 61 year(s)
 
 
  • Figure 1
    Chest X-ray

    Bilateral interstitial alteration without loss of volume. Increased caliber of pulmonary arteries (yellow arrows).

     
    Area of Interest: Respiratory system; Imaging Technique: Conventional radiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Cysts;
     
     
  • Figure 2
    Unenhanced coronal chest CT

    Diffuse, symmetric parenchymal involvement, with cystic changes in lower lung lobes and fibrosis in upper lung lobes.

     
    Area of Interest: Respiratory system; Imaging Technique: CT-High Resolution; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Cysts;
     
     
  • Figure 3
    Unenhanced axial chest CT (upper lung lobes)

    Shows cysts (most of 5mm) and peribronchial fibrotic changes.

     
    Area of Interest: Respiratory system; Imaging Technique: CT-High Resolution; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Cysts;
     
     
  • Figure 4
    Unenhanced axial chest CT (lower lung lobes)

    Notice the irregular cysts, with a size less than one centimeter and confluent.

     
    Area of Interest: Respiratory system; Imaging Technique: CT-High Resolution; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Cysts;
     
     
  • Figure 5
    Pathological anatomy
     

    Granuloma constituted by Langerhans cells. These cells have a slightly eosinophilic clear cytoplasm and a nucleus with a central cleft. (HE stain).

     
    Area of Interest: Respiratory system; Imaging Technique: Percutaneous; Procedure: Biopsy; Special Focus: Pathology;

    Immunohistochemical staining for CD1a is positive, characteristics of the PLCH.
