Role of the Ear in Meningitis: A Narrative Review of Neuroimaging

Abstract

Background/Objectives: Meningitis is a life-threatening condition often associated with ear pathology. This narrative review explores the critical role of the ear in Meningitis, emphasizing neuroimaging findings. Methods: Congenital malformations of the inner ear may significantly increase the risk of recurrent Meningitis, especially in children. Otomastoiditis, through direct extension or bony erosion, is a frequent cause of otogenic Meningitis. Cholesteatoma can erode bone and lead to severe intracranial complications, including Meningitis. Imaging is essential for early detection of bone defects, intracranial extension, and associated complications. Labyrinthitis and vestibulocochlear neuritis are usually complications of Meningitis. Less frequently, Meningitis may follow ear surgeries, such as cochlear implantation or mastoidectomy. Conclusions: Neuroradiologists must be aware of ear conditions associated with Meningitis to enable prompt diagnosis and correct management.
