AP radiograph of the neck (above) shows the VP shunt catheter is broken at the level of the mid-neck. Axial CT without contrast of the brain obtained one year ago (below left) shows the tip of the VP shunt in the left lateral ventricle and the ventricular system to be decompressed. Current axial CT without contrast (below right) shows the tip of the VP shunt to be in the left lateral ventricle and interval development of dilation of the ventricular system.
