Lingular Pneumonia Obscured by Implanted Cardioverter-Defibrillator: Lateral Thinking

A 56-year-old female with an implanted cardioverter-defibrillator was admitted with a short history suggestive of a diagnosis of pneumonia. An AP radiograph did not identify an area of consolidation. A subsequent lateral radiograph highlighted an extensive left-lingular-lobe consolidation that had been obscured by the cardiac device. This case highlights the fact that large devices can obscure significant pathology, and that lateral or cross-sectional imaging may be helpful in reaching a diagnosis.
