3. There is now definite lung involvement on the left
The calcium present in the left hilar region is small, eccentric and likely old. While eccentric calcification within a nodule suggests the nodule is more likely benign than malignant, eccentric (and stippled) patterns of calcification within pulmonary nodules can be seen in malignancies.

There is now definite lung involvement on the left which is new compared to the previous CT scan.
