Test two

  1. mediastinal masses-anterior
    • lymphadenophaty-most common-lymph nodes larger than 1cm are enlarged
    • thyroid
    • thymus
    • teratomas
  2. Mediastinal masses-middle
    • Lymphadenophaty
    • Aortic aneurysms
  3. Lymphadenopathy
    • malingnat-lumphomas; SCLC; Mets (breast)
    • Benign-infection (mono or Tb)
  4. Aortic Aneurysms
    • Persistent above 4cm
    • 5-6cm risk of rupture
  5. Mediastinal Masses-Middle
    Aortic Dissection
  6. Aortic Dissection
    • Abrubt onset of pain
    • MRI-most sensitive but CT good as well
    • Radiograph-widened mediastinum, left pleural effusion, loss of aortic arch shadow, deviation of trachea and esophagus to the right.
  7. Mediastinal masses-posterior
    • Neurogenic tumors-can cause bone changes in spinal canal and ribs.
    • May have pleural effusions
  8. Nodule vs mass
    • <3cm nodule
    • >3cm mass
  9. Bening Nodules
    • Granulomas-may result post-infection
    • Hamartomas-peripherally located "popcorn appearance
  10. Bronchogenic Carcinoma
    • Seeing a solitary nodule/mass
    • seeing the effects of it suchas pneumonitis or atelectasis
    • seeing direct or metastiatic spread
    • common
  11. Lung cancers with spread
    • Direct extension
    • Hilar adenopathy
    • Mediastinal adenopathy
    • Pleural effusion from lymphagitic spread
    • Mets to bone
  12. Multiple nodules
    most often think mets, defferent sizes-small to cannon ball

    Lymphangitic spread-lung, breast, pancreas--unilateral pulmonary edema.
  13. Cavities
    Bronchogenic-thick wall and irregular inner margin

    Tb-thin wall and smooth inner margin

    Abscess-thick wall and smooth inner margin
