It represents a bony depression in the skull base. The authors here report the case of a fossa navicularis magna in a 9-year-old female who had been treated for recurrent episodes of meningitis.<\/jats:p><jats:p>A literature review was also done to highlight the unique features and clinical importance of this distinctive radiological skull base finding. The literature search covered papers from the 19th century up to 2018. Earlier authors described \u201cfossa navicularis\u201d as a very rare skull base finding. So far, only three cases of fossa navicularis with associated clival or intracranial infection have been reported in the literature. This is the fourth reported case, and the defect was closed endoscopically via a transnasal route. This morphological skull base anomaly should be considered in the differential diagnoses for an unexplained skull base infective pathology.<\/jats:p><jats:p>Skull base surgeons should be aware of the existence of the fossa navicularis because of its clinical importance in rendering a prompt diagnosis and appropriate treatment.<\/jats:p>","DOI":"10.3171\/2018.5.peds18157","type":"journal-article","created":{"date-parts":[[2018,7,27]],"date-time":"2018-07-27T13:55:40Z","timestamp":1532699740000},"page":"523-527","source":"Crossref","is-referenced-by-count":14,"title":["Fossa navicularis in a pediatric patient: anatomical skull base variant with clinical implications"],"prefix":"10.3171","volume":"22","author":[{"given":"Andrew F.","family":"Alalade","sequence":"first","affiliation":[{"name":"Victor Horsley Department of Neurosurgery, National Hospital for Neurology and Neurosurgery, London, United Kingdom;"},{"name":"Queensland Skull Base Unit, Princess Alexandra Hospital, Brisbane, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Briganti","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Universit\u00e9 libre de Bruxelles, Brussels, Belgium;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo-Lyn","family":"Mckenzie","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Lady Cilento Children\u2019s Hospital, Brisbane;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitesh","family":"Gandhi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Princess Alexandra Hospital, Brisbane;"},{"name":"Queensland X-Ray, Brisbane; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Damian","family":"Amato","sequence":"additional","affiliation":[{"name":"Queensland Skull Base Unit, Princess Alexandra Hospital, Brisbane, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benedict J.","family":"Panizza","sequence":"additional","affiliation":[{"name":"Queensland Skull Base Unit, Princess Alexandra Hospital, Brisbane, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Bowman","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Lady Cilento Children\u2019s Hospital, Brisbane;"},{"name":"Queensland Skull Base Unit, Princess Alexandra Hospital, Brisbane, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Forensic Sci Int","doi-asserted-by":"publisher","first-page":"161","DOI":"10.1016\/j.forsciint.2010.04.009","article-title":"Analysis of time of closure of the spheno-occipital synchondrosis using computed tomography","volume":"200","author":"Bassed RB","year":"2010","unstructured":"Bassed RB, Briggs C, Drummer OH: Analysis of time of closure of the spheno-occipital synchondrosis using computed tomography.
