2 Micronodular(miliary)disease  TB  Histoplasmosis  Chicken box  Sarcoidosis  LCH  Pneumoconiosis  Alveolar microlithiasis  Metastasis

3 Septal thickening  Beaded / nodular * lymphangitic carcinomatosa * sarcoidosis * silicosis  Smooth * lymphangitisc carcinomatosis * pulmonary edema * alveolar proteinosis

4 Bilateral perihilar air- space disease  Pulmonary edema  Pulmonary hemorrhage  Alveolar proteinosis  PCP

5 Acute alveolar infiltrate  Pulmonary edema  Pneumonia  Pulmonary hemorrhage  Aspiration

6 Chronic alveolar disease  Alveolar cell carcinoma  Alveolar sarcoidosis  Lymphoma  Alveolar proteinosis

7 Unilateral hyperlucent lung  Obstructive emphysema  Mcleoid syndrome ( Swyer James syndrome)  Pneumothorax  Pulmonary embolism  Bullous disease  Air trapping e.g. FB, mass  Poland syndrome

8 Multiple lung nodules (macronodules)  Metastasis  Wegner’s granulomatosis  Rheumatoid n nodules  AVMs  Septic emboli

9 Small cavitating lung lesions  Septic emboli  Rheumatoid nodules  Wegner’s granulomatosis  Sq. or transitional cell ca metastasis

10 Upper lober disease ( CASSET P )  Cystic fibrosis  Ankylosing spondylitis  Sarcoidosis  Silicosis  Esinophilic granuloma  PCP

11 Basilar interstitial lung disease ( BADASS )  Bronchiectasis  Aspiration  Drugs / DIP-UIP  Asbestosis  Sickle cell disease  Scleroderma

12 Masses with air bronchogram  Lymphoma  Alveolar cell carcinoma  Pseudolymphoma ( maltoma )

13 Anterior mediastinal mass  Thymic tumors  Substernal Thyroid  LNs  Germ cell tumor

14

15 Middle mediastinal mass  LNs  Aneurysm  Esophageal duplication  Bronchogenic cyst

16 Posterior mediastinal mass  Neurogenic tumors  Paraspinal hematoma  Paraspinal abscess  Extraskeletal hematopoiesis  LNs enlargement  Lateral meningeocele

17 Opacified hemithorax  Atelectasis  Pneumonia  Pleural effusion  Post pneumonectomy

18 Pneumomediastinum  Ruptured esophagus  Ruptured trachea / bronchus  Iatrogenic  Broncheal asthma  pneumoperitoneum

19 Pleural calcification  Old TB empyema  Asbestos exposure  Hemithorax

20 Cardiopherenic angle mass  Pericardial cyst  Diaphragmatic hernia ( Morgagni )  Lung sequestration  Pericardial fat bad

21 Unilateral pulmonary edema  Aspiration  Disease in other lung e.g. COPD  Postural  Rapid expansion pulmonary edema “ Look for ICT”

22 Long segment tracheal narrowing  Tracheopathia osteoplastica  Tracheo-broncheal amyloidosis  Wegner’s granulomatosis  Intubation injury  Tracheobronchomalacia  Relapsing polychondritis  Papillomatosis ( extensive )

23 Peripheral distributed lung disease  Esinophilic pneumonia --- upper lobes  BOOP lower lobes  Hypersensitivity pneumonitis  Multiple infarcts  DIP  Alveolar cell carcinoma

24 Bronchiectasis  CT criteria of bronchiectasis 1- lack of tapering of bronchi 2-internal diameter of bronchus larger than the adjacent artery 3- bronchi are visible within 1 cm of pleura 4- mucus-filled, dilated bronchi

25 Bronchiectasis  Chronic airway infection  Pulmonary fibrosis –traction bronchiectasis  ABPA central bronchiectasis  Cystic fibrosis apical bronchiectasis  Mounier-Kuhn syndrome – tracheobronchomegally  Kartagner syndrome --- situs inversus + sinusitis

26 Mounier-Kuhn syndrome

27 ABPA

28 Cystic fibrosis

29 Kartagener’s syndrome

30 Dilated esophagus  Scleroderma  Achalasia  Obstructing tumor  Drugs ( atropine)  Surgury ( gastric pull-up)
