Hemifacial spasm and trigeminal neuralgia in Chiari's I malformation with hydrocephalus: case report and literature review.Clin Neurol Neurosurg. 2014 Jul; 122:64-7.CN
Chiari's I malformation with hydrocephalus is commonly seen in clinical experience. Trigeminal neuralgia (TN) and hemifacial spasm (HFS) are most commonly related to vascular compression of the root entry/enter zone (REZ). Until now, TN and HFS associated with hydrocephalus caused by Chiari's malformation have not been reported. The patient was a 24-year old male with left HFS and ipsilateral TN. Arnold-Chiari's I malformation with hydrocephalus and platybasia were found in magnetic resonance imaging (MRI) of brain. We underwent a programmable ventriculoperitoneal shunt with complete resolution of all symptoms. This is the first report of one case only presenting as coexistent ipsilateral TN and HFS secondary to Chiari's I malformation with hydrocephalus.
