Normal Lung – Small Comet tail seen (Probable small amount of fibrosis / fluid in alveolus)
Hepatised Vs Normal
Normal Lung
Minimal movement but tiny comet tail seen between pleural layersNormal lung with sliding visible below the pleural lines – No Pneumo!!
Pleural Effusion
Pneumothorax Patterns
Moving lung on R. with B lines and Pneumo on L. dead still air. Lung point visible too as pleura slides to meet pneumoR. of image is no sliding and accentuated A lines. L. shows junction with normal lung and Lung point = pneumoSubtle small ant. pneuma – N lung with sliding on L. Pneumo (accentuated A lines) on R obscured intermittently by cardiac pulsation.Sliding pleura L. then non sliding on R. meets sliding = Lung point = PneumothoraxDouble Lung Points seen hereSubtle – loss of comet tails and B lines with accentuated, still A linesSliding Lung on L. Pneumothorax on R.Lung Point – Visible on L, where parietal and visceral pleura surfaces In the presence of a pneumothorax the visceral pleura falls away from the parietal pleura. The point at which the two pleural surfaces touch is called the lung point.Subtle – bright pleural line and minimal slide in-between ribs
