Abstract
- Acquired Chiari malformation is a term describing the low lying cerebellar tonsils subsequent to the documentation of a normal hind brain. It is radiograpnhically indistinguishable from Chiari-I type malformation. Ventricular and lumbar shunting are known predisposing factors in patients who develop such tonsilar descent. Managements of acquired Chiari malformations include ventriculoperitoneal(V-P) shunt. Ventriculoatrial(V-A) shunt or posterior fossa decompression after removal of lumboperitoneal(L-P) shunt. The authors recently have encountered a patient who developed an acquired chiari malformations after V-P shunt for hydrocephalus associatd with neurocysticercosis. This case of chiari malformation is presented as our report, together with pertinent literature review.
