Malfunction of the shunt with infection , symptoms of raised ICT and fever , that is the common cause , lower limb fibres are carried more out wards in the spinal cord compared to upperlimb fibres which are more inside in the spinal cord so in increased ICT CSF presuure is increased in spinal canal causin lower limb fibres compression first leading to the above presentation
