Because of nonspecific symptoms, it is usually diagnosed when complications such as meningitis occur. Cerebrospinal fluid leak may be caused by cochlea malformation, which permits nonphysiological communication between subarachnoid space and tympanomastoid cavity. Nearly 20% of congenital sensorineural hearing loss is connected with inner ear bone malformation. We present a case of 40-year-old man suffering since early childhood from recurrent meningitis and right ear deafness, caused by congenital internal ear malformation. For many years, patient with sensorineural hearing loss had not undergone diagnostic radiology; computed tomography scans of the temporal bone had not been performed. Developing meningitis in early childhood was regarded as the reason for deafness.<\/jats:p>","DOI":"10.1177\/0145561320920399","type":"journal-article","created":{"date-parts":[[2020,4,22]],"date-time":"2020-04-22T16:25:55Z","timestamp":1587572755000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Recurrent Meningitis in Congenital Inner Ear Malformation"],"prefix":"10.1177","volume":"100","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5824-8709","authenticated-orcid":false,"given":"Aleksander","family":"Zwierz","sequence":"first","affiliation":[{"name":"Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University"},{"name":"Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krystyna","family":"Masna","sequence":"additional","affiliation":[{"name":"Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawe\u0142","family":"Burduk","sequence":"additional","affiliation":[{"name":"Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,4,22]]},"reference":[{"key":"e_1_3_2_2_2","unstructured":"Hanson MB.
