CTICasesComputer-Aided Detection (CAD) Miss of a Right Upper Lobe Lung Cancer
Imaging findings
A chest radiograph processed through a computer-aided detection (CAD) system flags three findings, none of which correspond to the actual abnormality; review of the original radiograph instead shows a subtle abnormal contour along the right superior mediastinal margin with fullness of the paratracheal stripe, which CT confirms represents a sizable right upper lobe cancer at the thoracic inlet.
Key takeaways
Over-reliance on CAD-flagged regions can cause a real finding outside those regions to be overlooked, particularly at the thoracic inlet near the first rib -- a location cancers characteristically hide -- reinforcing that images should be interpreted independently before reviewing CAD prompts.
