Palsy of the Contralateral Abducens Nerve after Aneurysm Surgery and Temporal Meningioma in the Presence of Petroclival Meningioma: A Case Report

Abstract

The sixth abducens nerve is subject to injury after rare complications of intracranial hypotension caused by procedures such as dural punctures and spinal surgeries. The purpose of this case report is to discuss the mechanism of nerve palsy in these situations. Therefore, we describe a case of onset of contralateral sixth cranial nerve palsy after intracranial aneurysm and temporal meningioma surgery. Moreover, in this case there is a singularity due to the presence of the petroclival meningioma that amplified the unfolding of the lesion.

Resumo

O sexto nervo abducente está sujeito a lesões após raros eventos de hipotensão intracraniana gerada por procedimentos como punções de dura-máter e cirurgias de coluna. O propósito deste relato de caso é discutir o mecanismo da paralisia deste nervo nestas situações. Para isso, descrevemos um caso de aparecimento de paresia do sexto nervo craniano contralateral após cirurgia de aneurisma intracraniano e de meningioma temporal. Além do mais, neste caso há uma singularidade em razão da presença do meningioma petroclival contralateral, que amplificou o desdobramento da lesão.
