Pseudotumor cerebri: as a cause for early deterioration after Chiari I malformation surgery.
BACKGROUND
Chiari I malformation is associated with a small posterior fossa which cannot accommodate a growing hindbrain. Pseudotumor cerebri has been linked to developmental posterior fossa malformations.


METHODS
The authors present two cases of early-deterioration post-Chiari I malformation surgery in a young and an adult patient, which were linked to raised intracranial pressure and had a stormy post-operative period. The pathophysiology of pseudotumor cerebri in early post-operative complications of Chiari malformation surgery is addressed along with arguments favoring its association.


CONCLUSIONS
Potential clinical risk factors and red flags linking pseudotumor cerebri and Chiari malformation patients are discussed. The management of post-operative complications produced by the association is addressed.
