Pathology involving the ASB is rare but the causes are manifold and can be broadly subdivided into those intrinsic to the skull base and processes extending from below or above. Sinonasal pathology is the most commonly encountered and poses significant management challenges that rely heavily on accurate interpretation of the radiological findings. We illustrate the normal anatomy of the ASB and present a cross-sectional imaging review of the pathological entities that may be encountered, focusing on the specific features that will impact on clinical and surgical management.<\/jats:p>","DOI":"10.1177\/2058460118776487","type":"journal-article","created":{"date-parts":[[2018,5,23]],"date-time":"2018-05-23T04:49:56Z","timestamp":1527050996000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Imaging review of the anterior skull base"],"prefix":"10.1177","volume":"7","author":[{"given":"Olivia","family":"Francies","sequence":"first","affiliation":[{"name":"Department of Radiology, St Bartholomew\u2019s and The Royal London Hospitals, Barts Health NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Levan","family":"Makalanda","sequence":"additional","affiliation":[{"name":"Department of Radiology, St Bartholomew\u2019s and The Royal London Hospitals, Barts Health NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitris","family":"Paraskevopolous","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Royal London Hospital, Barts Health NHS Trust, London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashok","family":"Adams","sequence":"additional","affiliation":[{"name":"Department of Radiology, St Bartholomew\u2019s and The Royal London Hospitals, Barts Health NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,5,23]]},"reference":[{"key":"bibr1-2058460118776487","doi-asserted-by":"publisher","DOI":"10.5152\/eajm.2013.23"},{"key":"bibr2-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1016\/j.rcl.2016.08.009"},{"key":"bibr3-2058460118776487","doi-asserted-by":"publisher","DOI":"10.4103\/0971-3026.82283"},{"key":"bibr4-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2008.01.017"},{"key":"bibr5-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1097\/RMR.0b013e31815711b7"},{"key":"bibr6-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.11101821"},{"key":"bibr7-2058460118776487","doi-asserted-by":"publisher","DOI":"10.2147\/TCRM.S2379"},{"key":"bibr8-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1055\/s-2004-817700"},{"key":"bibr9-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2008.01.059"},{"key":"bibr10-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1016\/j.nic.2009.06.011"},{"key":"bibr11-2058460118776487","doi-asserted-by":"publisher","DOI":"10.2500\/ar.2013.4.0064"},{"key":"bibr12-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1148\/rg.305105040"},{"key":"bibr13-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199707000-00005"},{"key":"bibr14-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1067\/j.cpradiol.2015.10.004"},{"key":"bibr15-2058460118776487","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1128"},{"key":"bibr16-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1055\/s-0031-1287687"},{"key":"bibr17-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1055\/s-0030-1262945"},{"key":"bibr18-2058460118776487","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2014.28.3978"},{"key":"bibr19-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1102\/1470-7330.2012.0015"},{"key":"bibr20-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1543995"},{"key":"bibr21-2058460118776487","first-page":"331","volume":"21","author":"Borges A","year":"2000","journal-title":"Am J Neuroradiol"},{"key":"bibr22-2058460118776487","doi-asserted-by":"publisher","DOI":"10.1002\/hed.24152"},{"key":"bibr23-2058460118776487","first-page":"5","volume":"25","author":"Chang PC","year":"2004","journal-title":"Am J Neuroradiol"},{"key":"bibr24-2058460118776487","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1055\/s-0036-1583542","volume":"77","author":"Dublin AB","year":"2016","journal-title":"J Neurol Surg B"},{"key":"bibr25-2058460118776487","first-page":"Doc03","volume":"14","author":"Gassner HG","year":"2016","journal-title":"GMS Curr Top Otorhinolaryngol Head Neck Surg"},{"key":"bibr26-2058460118776487","unstructured":"Deschler DG, Moore MG, Smith RV, editors.
