Bronchogenic carcinoma

  1. 1. Bronchogenic carcinoma Dr / Hytham Nafady
  2. 2. Pathology
  3. 3. Symptoms of local chest disease: • Cough. • Hemoptysis. Symptoms of chest wall invasion: • Chest pain. Symptoms of mediastinal invasion: • e.g. superior vena cava syndrome (dilated anterior chest wall veins). Symptoms of distant metastases: Constitutional symptoms: • Weight loss. • Malaise. • Weakness. Paraneoplastic syndromes: CP
  4. 4. Causes of hemoptysis
  5. 5. Paraneoplastic syndromes • Migratory thrombophlebitis. • Cerebellar degeneration. • Eaton Lambert syndrome. • Hypertrophic osteoarthropathy. • Hypocalcemia (ectopic PTH). • Hypercalcemia (ectopic cacitonin). • Ectopic ACTH • SIADH
  6. 6. Radiological manifestations of BC 1. Hilar enlargement & increased density. 2. Bronchial obstruction. 3. Pulmonary mass lesion. 4. Pulmonary nodule. 5. Mediastinal involvement. 6. Pleural effusion. 7. Chest wall involvement. 8. Bone involvement. 9. Metastases.

  10. 10. DD of hilar enlargement
  11. 11. DD of hilar lymphadenopathy
  12. 12. Pulmonary plethora • Infant with VSD. • Cardiomegagly , prominent pulmonary conus & Pulmonary plethora are suggestive of left to right shunt
  13. 13. Pulmonary hypertension
  14. 14. • Prominent main pulmonary artery segment (MPA), which appears to be aneurysmally dilated. • Right pulmonary artery (RPA) is also enlarged. • Enlargement of right pulmonary artery differentiates it from the post stenotic dilatation of main pulmonary artery in pulmonary stenosis. • In post stenotic dilatation, even though the left pulmonary artery which is in line with the main pulmonary artery may be dilated, the right pulmonary artery which does not have the effect of the jet and eddy currents, is not dilated. • This X-ray also shows a prominent right atrial contour, indicating right atrial dilatation as a consequence of pulmonary hypertension and right ventricular hypertrophy. • The end on views of blood vessels seen through the right pulmonary artery shadow are tiny, indicating that the RPA dilatation is unlikely to be due to increased pulmonary blood flow. Large end on vessels are a feature of pulmonary hypertension due to excessive left to right shunt causing increased pulmonary blood flow. In this case, the absence of them would make one think that the severe pulmonary hypertension is probably primary. • The right ventricular systolic pressure and hence the pulmonary artery systolic pressure estimated by continuous wave Doppler interrogation of the tricuspid regurgitation jet was over 110 mm Hg.
