  40. 40. What is rounded atelectasis and its relation with pleural fibrosis • When pleural fibrosis is significant, contguous to it pripheral atelectasis occurs, merely representing lobar collapse mistaken for tumor
  41. 41. What is focal fibrosis and what are the causes Extent of fibrosis may vary from nodular lesions to extensive areas- causes are • coal worker’s pneumoconiosis • Asbestosis • silicosis
  42. 42. What is replacement fibrosis and what are the causes • Fibrous tissue replaces the lung parenchyma by suppuration or infarction Common causes of replacement fibrosis- • Pulmonary tuberculosis • Bronchiectasis • Lung abcess • Pulmonary infarct • Necrotizing pneumonias
  43. 43. Clinical features of replacement fibrosis • Common cause is pulmonary tuberculosis • Upper lobes are affected most frequently • Fibrosis is usually associated with bronchiectasis • History of cough/ with or without expectoration and dysnoes/sputum may be blood tinged
  44. 44. Clinical features of replacement fibrosis • Common cause is pulmonary tuberculosis • Upper lobes are affected most frequently • Fibrosis is usually associated with bronchiectasis • History of cough/ with or without expectoration and dysnoes/sputum may be blood tinged
  45. 45. What is interstitial fibrosis and what are the causes • Diffuse fibrosis of lung parenchyma which is the end result of interstitial lung disease:- • Connective tissue disorders • Radiation injury to lung • Cryptogenic fibrosing alceolitis • Extrinsic allergic alveolitis • Idiopathic pulmonary hemosiderosis • Drugs:NFT/amiodarone/methotrexate/bleomycin • busulphan
  46. 46. Auscultation in fibrosis • In extensive fibrosis the intensith of breath sound is diminished and vesicular in character with prolonged expiration • VR ↓ • Coarse crepitations are heard
  47. 47. COMMON CAUSES OF FIBROTHORAX • Empyema • Pleural effusion • Traumatic hemothorax • tuberculosis
  48. 48. Uncommon causes of fibrothorax • Benign asbestos pleural effusion • Connective and collagen vascular disorders • Uremia • Paragonimiasis • Drug induced
  49. 49. Drugs causing pleural fibrosis • Ergot alkaloids • Bromocriptine • Pergoline • Methysergide • Methotrexate Drugs can cause associated parenchymal and peritoneal fibrosis
  50. 50. Clinical features of fibrothorax • Marked limitation of chest movements • Mediastinal shift to same side • Decrease in size of hemothorax • Crowding of ribs
