Abstract
BACKGROUND AND OBJECTIVE
Hypertrophic pachymeningitis is an infrequent inflammatory disease resulting in thickening and fibrosis of the dura mater. In most cases, the cause in unknown and is called idiopathic hypertrophic pachymeningitis (IHP). Audiovestibular symptoms are infrequent and the pathogenesis is still unclear.
MATERIALS AND METHODS
A systematic literature review of cases with IHP and vestibular symptoms from 2000 to February 2020 was performed. PRISMA Checklist was followed and PubMED database, Web of Science and Cochrane library were searched. We report a case of an adolescent with a diagnosis of vestibular neuritis in the context of IHP attended in our clinic.
RESULTS
We reviewed 5 articles related to IHP and vestibular disorders. A total of 7 cases (5 women and 2 men), with ages between 27 and 68 years with IHP were found. They all had audiovestibular symptoms. In contrast to our patient, uni or bilateral neurosensorial hearing loss was reported in all cases. Furthermore, there is no other case report published describing the association between IHP and vestibular neuritis. High dose steroids improved symptoms in 85.7% of the patients.
CONCLUSION
Vestibular symptoms in IHP are uncommon and the pathogenesis is still debatable. Entrapment of nerves in the internal auditory canal and secondary neuronal damage could be suspected as the main cause of hearing and vestibular loss.
