Abducens Nerve Schwannoma: Case Report and Literature Review

Abstract

The authors describe a rare case of abducens nerve schwannoma, manifested with headache and diplopia, associated to right side cerebellar syndrome. During surgery, the authors identified that the origin of the tumor was from the abducens nerve, and the histopathological diagnosis confirmed that it was a schwannoma. A gross total tumor resection was performed, and the patient recovered from her symptoms 1 month after surgery. The authors followed the Case Report guidelines (CARE) guideline and the patient authorized the authors to publish the present case report by signing an informed consent form.

Resumo

Os autores descrevem um raro caso de Schwannoma do nervo abducente, cuja manifestação clínica foi com cefaleia e diplopia, associadas à síndrome cerebelar hemisférica direita. Durante a cirurgia, os autores identificaram que o tumor tinha sua origem junto ao nervo abducente, e o diagnóstico histopatológico confirmou schwannoma. Realizou-se uma ressecção completa do tumor e o paciente apresentou melhora total dos sintomas em um mês após a cirurgia. Os autores seguiram as diretrizes do CARE para produzir este relato e o paciente assinou o termo de consentimento livre e esclarecido, autorizando a publicação deste caso.
