School ager with meningitis with a ventriculoperitoneal shunt that was placed a week ago who has developed a new headache today

MRI of ventriculoperitoneal shunt malfunction due to migration of the tip of the shunt out of the ventricular system.
Axial T2 MRI without contrast of the brain immediately after ventriculoperitoneal shunt placement a week ago (left) shows the tip of the VP shunt placed from a left parietal approach to be in appropriate position in the the posterior horn of the left lateral ventricle. Axial T2 MRI of the brain from today (right) shows the tip of the ventriculoperitoneal shunt to no longer be within the left lateral ventricle but to be in the brain parenchyma.

The diagnosis was ventriculoperitoneal shunt malfunction due to migration of the tip of the ventriculoperitoneal shunt out of the left lateral ventricle.
