New Onset Persistent Refractory Hypertension after Medulloblastoma Excision in Children-An Indicator of Poor Prognosis: A Case Series

Chiari I malformation with neurogenic hypertension after suboccipital decompression

Patients with Chiari I malformations have a spectrum of symptoms related to craniocervical structural compression. Neurogenic hypertension has been reported in some patients with this disorder, with resolution of hypertension after suboccipital decompressions in some cases. The pathophysiology of neurogenic hypertension in these patients is thought to be related to ventrolateral medullary compression. The important role of the ventrolateral medulla in blood pressure control has been studied extensively. In this report, we present the case of a pediatric patient diagnosed with a Chiari I malformation who developed hypertension after a suboccipital decompression. We believe that this case demonstrates the important role of the ventrolateral medulla in neurogenic hypertension.
