title: Retroclival arachnoid cyst in a preterm infant after ventriculitis and intraventricular hemorrhage-a case report.
abstract: CONCLUSIONS
  We present a case of a preterm boy of 29 gestational weeks with complicated posthemorrhagic hydrocephalus who developed a retroclival cyst extending to the upper cervical spinal canal and leading to brainstem compression. At the age of 2 months, third ventriculocisternocystostomy (ETVCC) resulted in temporary relief but was followed by reclosure of the stoma within weeks. At the age of 4 months, navigated endoscopic ventriculocisternocystostomy and endoscopy-guided stent catheter placement was performed with connection to a ventriculoperitoneal (VP) shunt system through a burr hole reservoir.
  
  
  CONCLUSIONS
  This strategy improved the multiloculated hydrocephalus by establishing a communication between theretroclival subarachnoid cyst and the ventricular system, leading to uneventful further development of the child.
