Both meningiomas and schwannomas enhancing vividly on MRI. Meningiomas more\u0026nbsp;commonly cause hyperostosis than smooth remodeling of the skull base. They are usually isointense to grey matter on T2 weighted imaging, while schwannomas are T2 hyperintense, however meningiomas can be T2 hyperintense\u0026nbsp;and so signal\u0026nbsp;is not the most reliable distinguishing characteristic.\u0026nbsp;\u0026nbsp;\u003c/p\u003e","id":1582,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2803","nextQuestionPath":"/articles/meningioma/questions/969","relatedArticles":[{"id":19575,"title":"Schwannoma","link":"/articles/schwannoma?lang=us"}],"alsoUsedIn":[{"id":260,"kind":"Course","title":"Skull base: anatomy and pathology","link":"https://radiopaedia.org/courses/skull-base-anatomy-and-pathology"},{"id":588,"kind":"Course","title":"Radiology lectures for ENT Trainees - page 588","link":"https://radiopaedia.org/courses/radiology-lectures-for-ent-trainees/pages/588"},{"id":588,"kind":"Course","title":"Lectures by Jenny Hoang - page 588","link":"https://radiopaedia.org/courses/lectures-by-jenny-hoang/pages/588"},{"id":588,"kind":"Course","title":"Radiopaedia 2020 - Lectures Only - page 588","link":"https://radiopaedia.org/courses/radiopaedia-2020-exclusive/pages/588"},{"id":588,"kind":"Course","title":"Head \u0026 Neck Lectures - page 588","link":"https://radiopaedia.org/courses/head-neck-lectures/pages/588"},{"id":588,"kind":"Course","title":"2020 Virtual Conference Private Use - page 588","link":"https://radiopaedia.org/courses/2020-virtual-conference-private-use/pages/588"}],"stem":"\u003cp\u003eWhich characteristic would most help in\u0026nbsp;distinguishing\u0026nbsp;meningioma from schwannoma at\u0026nbsp;the skull base?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/1582"}],"attemptsPercentages":[{"alternativeId":"7884","percentage":66},{"alternativeId":"7883","percentage":6},{"alternativeId":"7886","percentage":8},{"alternativeId":"7885","percentage":19}],"promptToLogin":false,"questionManager":false,"articleId":"meningioma"}
