Left lower lobe pneumonia – lateral CXR

Left lower lobe pneumonia – lateral CXR

PA chest x-ray in this patient with cough and fever shows consolidation (arrow) in the left lung base. It isn’t obscuring the left heart border or diaphragmatic silhouette, making it difficult to know which lobe it’s in. A lateral view was obtained and shows that the consolidation is located posteriorly (arrows), and so must be in the lower lobe.
