    • Wegener’s Granulomatosis
    • NODULES OF WEGENER”S GRANULOMATOSIS, aka GRANULOMATOSIS WITH POLYANGIITIS, GPA
      65 year old female presents with epistaxis and with nodular changes on CXR (a) magnified in b.
      CT scan in axial projection (c) and magnified in d, reveals 3 types of nodules.
      A spiculated solid nodule (red arrow head) is magnified in e, a bronchocentric nodule (teal arrowhead) is magnified in e. This may represent a cavitating nodule or hemorrhagic change around a bronchiole (cheerio sign) A ground glass nodule (white arrowhead) is magnified in g.

    • Langerhans Cell Histiocytosis
    • Spiculated Nodule of Langerhans Cell Histiocytosis in a background of Centrilobular Emphysema

      Langerhans Cell Histiocytosis
      Langerhans Cell is a dendritic white cell with a wavy nucleus that creates granulomas and infiltrates the interstitium. It thus causes spiculated nodules that appear as spiculated nodules on CT

    • Idiopathic Pleuro-parenchymal Fibroelastosis
    • IDIOPATHIC PLEUROPARENCHYMAL FIBROELASTOSIS
      83 year old man with COPD and emphysema presented with bilateral shoulder pain. X-ray examination of his shoulders revealed a stellate nodule in his LUL. CT showed evidence of emphysema with a 15x14mm nodule with evidence of surrounding scarring and retraction.
      On PET scan the nodule was PET avid with an SUV of 4.5 consistent with a malignant neoplasm
      Surgery was performed and the pathology was consistent with idiopathic pleuroparenchymal fibroelastosis
      Follow up CTs 5years following surgery have shown stability
