Figure 1
Selected thoracic CT images on axial view showing primary lung adenocarcinoma with both solid (asterisks) and ‘crazy paving’ (white arrow) appearances (A &B). B is a close up view of A. The area of ‘crazy paving’ is completely replaced by solid mass (C&D) while maintaining the same demarcation confirming that the ‘crazy paving’ is indeed tumour infiltration.
