Frontal CXR shows a retrocardiac infiltrate, with suggestion of air bronchograms and silhouetting of the diaphragm medially. There are ground glass changes in the remaining left lower lobe peripherally and a suggestion of a nodular infiltrate in the left upper lung zone. The are no findings to suggest volume loss. The CXR is most compatible with an acute pneumonia when taken in the clinical contextCourtesy Ashley Davidoff MD TheCommonVein.net 289Lu 136561 CXR Left Lower Lobe Pneumonia35-year-old woman, presents with dyspnea and fever.

Coronal CT shows a bronchocentric pneumonic infiltrate in the superior segment of the left lower lobe and extending into the medial basal segment, and silhouetting the medial aspect of the diaphragm. There is an adjacent region of ground glass infiltrate. These findings are consistent with a bronchopneumonia in the left lower lobe.Courtesy Ashley Davidoff MD TheCommonVein.net 289Lu 136560 CT Left Lower Lobe Bronchopneumonia35-year-old woman, presents with dyspnea and fever.
