• Croup (Steeple sign)
• Round Pneumonia: typically in paediatric patients mean age of 5. Due to underdeveloped lung architecture which limits spread of infection. See https://radiopaedia.org/articles/round-pneumonia-1
• Thoracic Neuroblastoma (case from: https://radiopaedia.org/cases/thoracic-neuroblastoma-3?lang=us)
• Pneumothorax (left sided)
• Pneumothorax (left sided apical)
• Pneumothorax (right sided) suggested by fractures of the right ribs 3-8 with obvious displacement of the 5th and 6th ribs and subcutaneous emphysema of the thoracic wall.. The thin pleural line and the lack of the pulmonary vessels in the right apex are clearly visible reflecting a pneumothorax.
• Pancoust Tumor suggested by opacification of right apex, erosion of first rib, elevated hilar prominence and mass affect on trachea. Hyperlucent hyperinflated lungs suggest background COPD
• Gas outlining the inferior surface of the right hemidiaphragm. Gas is probably also present below the left hemidiaphragm but it is more difficult to identify. Appearance is that of pneumoperitoneum.
• Right sided mastectomy demonstrates a hyperlucent right lower hemithorax
• Large left tension Pneumothorax
• Left sided 3rd-7th rib fractures with displacement of the 6th-8th rib
• Frontal and lateral chest x-rays demonstrate typical appearances of pectus excavatum most easily seen on lateral projection. Note the displacement of the heart towards the left and blurring of the right heart border
• Retrocardiac opacity with air-fluid filled which is non-cardiac or pulmonary in origin. Likely hiatus hernia
• Heart is positioned inversly. Upper abdominal organs are in their normal positions. Likely dextrocardia
• A plain chest radiograph showing a well-defined, rounded lucency in the retrocardiac region, consistent with a sliding hiatal hernia
• Right sided pleural effusion is present
• Dense right upper lobe consolidation as evidenced by bronchograms within the the sharp inferior border indicating its location within the upper lobe. Reduced volume in the right hemithorax and mild deviation of the trachea indicating a degree of associated volume loss. Indicates lobar pneumonia
• Right costophrenic angle is abnormally deepened (Deep sulcus sign) suggesting Pneumothorax
• Bilateral enlargement of the hila in keeping with lymphadenopathy. Normal lung volumes. No signs of interstitial lung disease or consolidation. No pleural effusion. Normal heart size. Mild right hemidiaphragm eventration (longstanding). Confirmed to be Sarcoidosis on further workup
• Patchy airspace opacities and interstitial thickening throughout both lungs suggestive of atypical Pneumonia.
