Is it bony or pulmonary?

There is a small oval lesion in the left lower zone (arrow). Do you think it is a pulmonary nodule or a bone lesion? 
Difficult isn't it?

The x-ray was repeated below. The 'nodule' has changed position slightly but its relationship with the rib is maintained. It is therefore a rib lesion viz a bone island.
