Isolated Peripheral Hypoglossal Nerve Palsy Associated with Arterial Hypertension Caused by Neurovascular Compression

Abstract

Italian

We report a case of isolated left peripheral hypoglossal nerve palsy caused by neurovascular compression associated with essential arterial hypertension. MR and MR-angiography revealed an anomalous course of the left vertebral artery and left PICA. A similar case, without arterial hypertension, was reported by Rollnik et Al.

According to Jannetta's hypothesis neurovascular compression of the brain stem may cause essential arterial hypertension. To our knowledge no other similar case of peripheral hypoglossal palsy and arterial hypertension caused by neurovascular compression has been reported.

The possible role of neurovascular compression in the pathogenesis of essential hypertension is briefly discussed.
