Presentation Transcript


1. RADIOLOGY D RANDA AL-HARIZY PROF INTERNAL MEDICINE

2. Abnormal Chest Views LUNG OPACITY Homogenous: a- Obliterating costophrenic angle and rising to axilla 1- Pleural effusion Tracheal shift to opposite side Massive (exceeds 2nd rib), moderate (between 2nd+4th rib), mild (below 2nd rib). Look for fracture ribs to exclude hemorrhagic effusion Obliterated costophrenic angle in P-A view first occurs when 200cc of fluid accumulates and 75cc in lat view 2- Hydropneumothorax: Horizontal fluid level

9. Abnormal Chest Views LUNG OPACITY Homogenous: b- Taking shape of a lobe 1- Consolidation (pneumonia) Central trachea, normal lobe, normal ribs 2- Collapse: Trachea shift (same side) Shrunken lobe Elevated diaphragm Crowded ribs

27. Abnormal Chest Views LUNG OPACITY Homogenous: c- Coin shadow: “single rounded” describe 3s (site, size & shape) 1- Bronchogenic carcinoma – adenoma 2- Solitary metastases e.g. hypernephroma 3- Tuberculoma – gamma of syphilis – aspergilloma 4- Calcified cyst – foreign body 5- Pneumonic stage of lung abcess

31. APICAL SHADOW Pancoast tumor Apical TB fibrosis Pleural thickening Klebsiella pneumonia (Friedlander pneumonia) Apical collapse, fibrosis

34. Homogenous opacification of hemithorax Massive pleural effusion (+ shift of mediastinum to opposite side) Total lung collapse (+ shift of mediastinum to same side)
