Hypointense to grey matter\u0026nbsp;usually correlates with harder texture and more fibrous and calcified contents such as\u0026nbsp;psammomatous meningiomas.\u0026nbsp;\u003c/p\u003e","id":818,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/818","nextQuestionPath":null,"relatedArticles":[{"id":1659,"title":"Meningioma","link":"/articles/meningioma?lang=us"},{"id":14601,"title":"Microcystic meningioma","link":"/articles/microcystic-meningioma?lang=us"},{"id":33440,"title":"Psammomatous meningioma","link":"/articles/psammomatous-meningioma?lang=us"},{"id":42302,"title":"Angiomatous meningioma","link":"/articles/angiomatous-meningioma?lang=us"},{"id":42349,"title":"Secretory meningioma","link":"/articles/secretory-meningioma?lang=us"},{"id":42509,"title":"Cartilaginous meningioma","link":"/articles/cartilaginous-meningioma?lang=us"}],"alsoUsedIn":[{"id":1167,"kind":"Course","title":"Adult Neuroradiology Review Course - page 1167","link":"https://radiopaedia.org/courses/adult-neuroradiology-review-course/pages/1167"},{"id":1167,"kind":"Course","title":"Adult Neuroradiology Review Course - page 1167","link":"https://radiopaedia.org/courses/adult-brain-mri-review-course-2015-online-video/pages/1167"}],"stem":"\u003cp\u003eWhich of the following histological subtypes of meningioma is \u003cstrong\u003eLEAST\u003c/strong\u003e likely to demonstrate high T2 signal (i.e. significantly higher signal than adjacent brain parenchyma)?\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/818"}],"attemptsPercentages":[{"alternativeId":"4140","percentage":25},{"alternativeId":"4143","percentage":28},{"alternativeId":"4142","percentage":28},{"alternativeId":"4139","percentage":9},{"alternativeId":"4141","percentage":6},{"alternativeId":"4144","percentage":3}],"promptToLogin":false,"questionManager":false,"articleId":"chordoid-meningioma"}
