A young patient with history of right porencephalic cyst with communication to his ventricular system & subsequent shunted hydrocephalus.In past, he failed both ventriculoperitoneal shunt (vps) & ventriculopleural shunt due to pseudocyst formation/malabsorption.Most recent shunt revision was conversion to right side ventriculoatrial shunt.Pt was evaluated through physical medicine clinic & had x-rays to eval for potential scoliosis, which incidentally revealed that ventriculoatrial shunt had fractured with tubing dislodged into his left pulmonary artery.Branch.Echo showed fragment of catheter in left pulmonary artery.A few weeks later, cardiology removed the fragmented piece successfully in cath lab.
