Infant with a VP shunt and decreased activity for the last few days

Skull radiograph of VP shunt disconnection
Lateral radiograph of the skull obtained after VP shunt placement 3 months ago (above) shows all of the parts of the VP shunt to be connected together. Current lateral radiograph of the skull (below) shows an increasing space between the superior portion of the VP shunt and the reservoir beneath it, thus the superior part of the VP shunt is disconnected from the reservoir.

The diagnosis was ventriculoperitoneal shunt discontinuity.
