Right paraspinal line

Linea paraspinalis dextra

Definition

The right paraspinal line is the interface between the right lung and the paraspinous fat and soft tissues.

Normal radiographic appearance:

The right paraspinal line appears straight and runs from the 8th through the 12th thoracic vertebral levels.

The right paraspinal line has reportedly been seen on 23% of posteroanterior chest radiographs.

Abnormal radiographic appearance:

The paraspinal lines may be displaced laterally by prominent mediastinal fat or osteophytes. Abnormal contour or displacement may also suggest posterior mediastinal disease such as mediastinal hematoma, mass or extramedullary hematopoiesis.
