Review Case Reports
Interhemispheric arachnoid cyst in the elderly: case report and review of the literature.
Preoperative differential diagnosis of interhemispheric cysts is sometimes difficult. ⋯ It is highly possible that an interhemispheric cyst without agenesis of the corpus callosum in an adult is an arachnoid cyst.

Intracranial dissecting aneurysms have been associated with subarachnoid hemorrhage (SAH) or cerebral ischemia. We encountered a patient presenting with simultaneous subarachnoid hemorrhage and brainstem infarction caused by a dissecting aneurysm of the vertebrobasilar artery, which was diagnosed by magnetic resonance imaging (MRI) but did not show abnormal findings on cerebral angiography. ⋯ This is a rare case of a vertebrobasilar dissecting aneurysm that simultaneously caused both SAH and brain stem infarction. MRI should be performed in the acute phase of SAH of unknown origin to determine the possible coexistence of a dissecting aneurysm, as occurred in this case.

The purpose of this study was to establish standards for the pressure monitoring system and to define the pressure pattern during percutaneous trigeminal ganglion compression for treatment of trigeminal neuralgia. ⋯ The pressure monitoring system has proven to be accurate, reliable, and extremely useful for monitoring the percutaneous trigeminal ganglion balloon compression procedure.
