    Transient orthostatic hypertension after partial cerebellar resection
    (2011) Idiaquez, Juan; Fadic, Ricardo; Mathias, Christopher J.
    An effective baroreflex and autonomic pathways normally ensure that blood pressure (BP) is satisfactorily maintained, despite various stimuli in daily life that include postural changes. We describe a 20-year-old man with a cerebellar hematoma and acute hydrocephalus, who had a vermian and partial right cerebellar hemisphere resection followed by orthostatic hypertension (OHT) and mutism. On standing his systolic BP rose over 60 mmHg with a fivefold increase in plasma noradrenaline. After a period of 8 weeks, postural BP regulation improved along with his ability to communicate. We conclude that transient impairment of cerebellar autonomic modulation or dysfunction of the baroreflex medullary circuit, may have resulted in OHT.
