What is the Suprasellar region?
What is the Suprasellar region?
The suprasellar cistern is a cerebrospinal fluid filled space between the top of the pituitary and bottom of the hypothalamus. The pituitary stalk normally courses through this space to enter the pituitary gland and is critical for the normal operation of the pituitary.
Where is the Sellar region?
The area immediately around the pituitary, the sellar region and parasellar region, is an anatomically complex area that represents a crucial crossroads for important adjacent structures. The pituitary gland and sella are located below the center of the brain in the center of the skull base.
What is Sellar Suprasellar?
The sellar region includes the sella turcica and the pituitary gland, together with the ventral adenohypophysis and dorsal neurohypophysis. The parasellar region encompasses the cavernous sinuses, suprasellar cistern, hypothalamus, and ventral inferior third ventricle.
What is Suprasellar extension?
Hardy’s classification of the suprasellar extension of pituitary adenomas uses the relationship of the superior capsule of the tumor with the third ventricle and takes into account asymmetric extension in the coronal plane [4].
What is the most common pituitary tumor?
A large majority of pituitary adenomas are benign and are relatively slow growing. Adenomas are by far the most common disease affecting the pituitary gland. These tumors most commonly affect people in their 30s or 40s, although they can be diagnosed in children as well.
Why is it called Rathke pouch?
It is named for Martin Rathke.
What is the Diaphragma Sellae?
The diaphragma sellae is a sheet of dura mater that forms the roof of the pituitary fossa. It is described as a two-layer sheet of dura mater that merges anteriorly with the dura covering the planum sphenoidale and the anterior cranial fossa and posteriorly with the dura covering the dorsum sellae and the clivus.
