Right paraspinal line

Assoc Prof Craig Hacking and Dr Henry Knipe et al.

The right paraspinal (also known as the paraspinous or paravertebral) line (or stripe) is a feature of frontal chest x-rays and is formed by the interface of the right lung and the posterior mediastinal soft tissue. 

The right paraspinal line can be laterally displaced by a range of posterior mediastinal pathology 1-3:​
