CTICasesLung Adenocarcinoma Obscured by Pacemaker Generator
Imaging findings
A PA chest radiograph appeared normal. The lateral view revealed a band of consolidation at the level of the aortic arch. A pre-operative CT scout, with the patient's arms raised, clearly showed a large adenocarcinoma in the area previously obscured by the overlying pacemaker generator on the PA view.
Key takeaways
External devices, such as pacemaker generators, can obscure significant underlying lung pathology on frontal chest radiographs. The lateral view is crucial for identifying lesions in such obscured areas. Raising the arms for CT scouts can help remove overlying artifacts.
