Non-contrast axial CT of the thorax demonstrating transit of the right distal catheter into the thoracic cavity. The catheter passes subcutaneously over the clavicle before piercing pectorals major, travelling deep to the muscle and entering the pleural space beneath rectus abdominis. The intra thoracic catheter is looped adjacent to the right heart border.
The left ventriculoperitoneal shunt catheter can be traced subcutaneously over the thorax.
