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

Hypertension in the clinical setting of posterior fossa tumors is a known entity and occurs due to medullary compression by the tumor. Such hypertension usually responds to tumor excision. Postoperative hypertension occurring after posterior fossa tumor excision has been attributed to brain stem edema in a single report earlier, which resolved without any intervention. Here, we report two pediatric patients who developed new onset refractory, persistent postoperative hypertension after medulloblastoma excision, and discuss possible causes and the prognostic significance of this condition.
