May 9, 2024 · The clivus (of Blumenbach) is the sloping midline surface of the skull base anterior to the foramen magnum and posterior to the dorsum sellae 1. Specifically, the clivus is formed by the sphenoid body and the basiocciput, which join at the spheno-occipital synchondrosis.

Sep 22, 2020 · See: normal bone marrow signal of the clivus. An important normal variant that can sometimes be mistaken for clival pathology is a prominent basilar venous plexus that can appear to erode the posterior surface of the clivus 4, as well as prominent clival diploic veins that may mimic masses of the body of the clivus 5. 1.

In this article, we highlight the important imaging features of various clival and paraclival pathologies to facilitate effective diagnosis, therapeutic planning, and management. Keywords: magnetic resonance imaging, skull base, clivus, abducens nerve, skull base neoplasms/complications.

Aug 30, 2024 · Bone marrow signal of the clivus changes predictably with age and is well assessed with midline non-contrast T1WI without fat saturation. As is seen in the rest of the body the proportion of yellow (fatty) marrow increases with age.

Nov 23, 2013 · The clivus is a bone of the central skull base formed from the basisphenoid and the basiocciput. During normal ageing, the clival marrow converts from haematopoietic with low-to-intermediate T1 signal to fatty high T1 signal. Low T1 signal in adults is a marker of disease. This review illustrates the main important diseases of the clivus.

As diseases of the clivus evade clinical evaluation imaging plays a pivotal role in establishing a diagnosis. This article combines the description of anatomy and pathology with an extensive pictorial essay.

Jan 19, 2013 · We retrospectively reviewed 330 T1-weighted sagittal images, 80 T2-weighted sagittal images, and 83 gadopentetate-dimeglumine-enhanced scans of normal adults to determine the MR appearance of the normal adult clivus.

Jun 28, 2011 · The clivus is one of the most central parts of the skull base. As diseases of the clivus evade clinical evaluation imaging plays a pivotal role in establishing a diagnosis. This article combines the description of anatomy and pathology with an extensive pictorial essay.

It can be evaluated very clearly in routine brain magnetic resonance imaging (MRI) dueto its central location. Quantitative and qualitative evaluation of the clivus and its changes according to age in a group of healthy people.

Jan 19, 2013 · The multiplanar capabilities of MR imaging provide superb visualization of the adjacent cranial nerves and vascular structures, aiding in surgical planning and radiation therapy. In this pictorial essay, the MR imaging, CT, and conventional radiographic findings of various clival and paraclival lesions are illustrated.
