What are Clinoid processes?
clinoid process any of three processes of the sphenoid bone (anterior, medial, and posterior). coracoid process a curved process arising from the upper neck of the scapula and overhanging the shoulder joint; called also coracoid.
What does anterior clinoid process mean?
The posterior border of small wing of sphenoid, smooth and rounded, is received into the lateral fissure of the brain; the medial end of this border forms the anterior clinoid process, which gives attachment to the tentorium cerebelli; it is sometimes joined to the middle clinoid process by a spicule of bone, and when …

What does Clinoid mean?

Where is anterior Clinoid process?
Background: The anterior clinoid process (ACP) is located close to the optic nerve, internal carotid artery, ophthalmic artery, and can be easily injured in an ACP-related surgery.
What is sella meningioma?
Tuberculum sellae meningiomas are a classic tumor of the anterior fossa that present in patients with gradual visual deterioration secondary to optic apparatus compression. If untreated, complete blindness can occur.
What is Pneumatization of right anterior Clinoid process?
[8], pneumatization of the anterior clinoid process can occur as part of the normal development of the sphenoid sinus, most often bilaterally, lined by respiratory epithelium with the potential of developing mucocele if its drainage is blocked.
What does asymmetric pneumatization of the anterior clinoid process mean?
Asymmetrically pneumatized anterior clinoid process may present a diagnostic challenge when seen on MRI and may be misinterpreted as a thrombosed aneurysm or a mass.
Is the anterior clinoid process hypointense or pneumatized?
The contralateral anterior clinoid process is pneumatized and appears extremely hypointense on all pulse sequences. A different patient for comparison purposes. There is asymmetric pneumatization of the anterior clinoid processes with the left side pneumatized.
How to characterize the anterior clinoid process on CT?
It is easy to characterize on CT. Asymmetrically underpneumatized anterior clinoid process contains normal marrow and surrounding cortical bone, and appears as high T1 iso-T2, non-enhancing structure. Completely pneumatized anterior clinoid process appears hypointense on all pulse sequences and may mimic the flow void of an aneurysm.
