[Monitoring of intracranial pressure difference between supra- and infratentorial spaces after posterior fossa tumor removal (case report)].

A clinical example shows that after a neurosurgical operation in posterior fossa there could appear intracranial pressure difference between supra- and infratentorial spaces. This difference develops due to pressure rise in posterior fossa and maintenance of this hypertension postoperatively. Hypertension in posterior fossa and intracranial difference are accompanied by brainstem reactions and temporary neurological disorders. While the pressure difference decreases and ICP in posterior fossa normalizes the neurological symptoms disappear. ICP in supratentorial space not necessarily correlates with ICP in infratentorial space. In some cases it is necessary to measure ICP in infratentorial space after posterior fossa surgery.
