The pituitary is not surrounded by CSF, which is limited to a small pocket superiorly, the hypophyseal cistern. Outside of the visceral meningeal layer are the veins of the cavernous sinus as well as smaller veins that connect the cavernous sinuses\u0026nbsp;(e.g. the intercavernous sinus). Inferiorly the next layer is the endosteal layer of the dura, and then bone. Fat is not a significant component of the region, with small amounts found in the cavernous sinuses and bone marrow.\u0026nbsp;\u003c/p\u003e","id":855,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2302","nextQuestionPath":"/articles/pituitary-gland/questions/854","relatedArticles":[],"alsoUsedIn":[{"id":80,"kind":"Course","title":"[TRIAL] Pituitary Region Learning Pathway - page 80","link":"https://radiopaedia.org/courses/trial-pituitary-learning-pathway/pages/80"},{"id":80,"kind":"Course","title":"Pituitary Region Learning Pathway - page 80","link":"https://radiopaedia.org/courses/pituitary-learning-pathway/pages/80"}],"stem":"\u003cp\u003eThe anterior pituitary\u0026nbsp;gland is immediately surrounded by...\u0026nbsp;\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/855"}],"attemptsPercentages":[{"alternativeId":"4326","percentage":66},{"alternativeId":"4323","percentage":5},{"alternativeId":"4324","percentage":8},{"alternativeId":"4325","percentage":19},{"alternativeId":"4327","percentage":2}],"promptToLogin":false,"questionManager":false,"articleId":"pituitary-gland"}
