The PA view shows the silhouette sign – the medial half of the left dome of the diaphragm is obscured by the consolidation process. There is left lower lobe pneumonia.
On the lateral view, the spine sign is positive. There is a triangular opacity over the lower vertebral bodies. Normally, the lower thoracic vertebral bodies appear darker compared with the vertebrae in the mid and upper thorax. This is because of the increased soft tissue densities over the upper and mid thoracic vertebra.
This child has pneumonia and should be treated with antibiotics.[/peekaboo_content]
