'Two-Birds-One-Stone' Approach for Treating an Infant with Chiari I Malformation and Hydrocephalus: Is Cerebrospinal Fluid Diversion as Sole Treatment Enough?

摘要

BACKGROUND: Chiari I malformation (CIM) is a disorder characterized by caudal displacement of the cerebellar tonsils below the foramen magnum. It is often associated with syringomyelia and occasionally with hydrocephalus. CIM is commonly treated by posterior fossa decompression with or without removal of the posterior arch of C1 and duraplasty, but the treatment for infants with symptomatic CIM is not well established. We present a case of symptomatic CIM in an infant that was successfully treated with a ventriculoperitoneal shunt (VPS) and discuss the importance of the pathophysiology in management decisions.
