  1. BASIC CHEST RADIOLOGY 3

  2. Diffuse disease of the lung is most marked in the mid and lower zones, as this is where the x- rays are going through most lung volume. • Some diseases have an upper lobe preponderance.

  3. TB RADIATION-CONFINED TO SIDE OD RADIATION FIELD ALVEOLITIS-EXTRINSIC ALLERGIC MORE MID ZONE ANKYLOSING SPONDYLITIS SARCOIDOSIS SILICOSIS-TOGETHER WITH PMF HISTIOCYTOSIS

  4. WIDESPREAD INTERSTITIAL SHADOWING IS USUALLY FIBROSIS and associated with volume loss. Main reason for normal/large volume with fibrosis is usually COPD A few rare causes are HISTIOCYTOSIS,NEUROFIBROMATOSIS, AND LLYMPHANGIOMYOMATOSIS OTHER CAUSES COLLAGEN VASCULAR D ALVEOLITIS UIP RADIATION DRUGS SICKLE, SCLERODERMA

  5. COLLAPSE-VOLUME LOSS EFFUSION-OFTEN WITH PASSIVE COLLAPSE AND NO SHIFT PNEUMONIA PNEUMONECTOMY

  6. REVERSE PULMONARY OEDEMA PULMONARY EOSINOPHILIA SARCOID PULMONARY CONTUSION

  7. MULTIPLE CALCIFIED PLEURAL PLAQUES ASBESTOS PLAQUES-NOT ASBESTOSIS

  8. UNILATERAL PLEURAL CALCIFICATION TB HAEMATOMA

  9. ANTERIOR MEDIASTINAL MASS ALWAYS INCLUDE TUMOUR AND ANEURYSM IN ALL DIFFERENTIAL OF MEDIASTINAL MASS.THEN THINK ANANTOMICALLY TUMOUR TERRATODERMOID-ALSO SEMINOMA THYMIC TUMOUR THYROID

  10. ANEURYSM OF AORTIC ARCH

  11. MIDDLE MEDIASTINUM LYMPH NODES CYSTS-ENTERIC/BRONCHOGENIC

  12. POSTERIOR MEDIASTINUM NEUROGENIC ABSCESS EXTRAMEDULLARY HAEMOPOIESIS METASTASE

  13. RT CARDIOPHRENIC MASS FAT PAD PERICARDIAL CYST MORGAGNI HERNIA
