Is pituitary Suprasellar?

Suprasellar meningiomas tend to affect middle-aged men and women, account for about 10 percent of all meningiomas, and occur near the pituitary gland and optic nerves at the skull base. These slow-growing tumors can cause severe visual impairment in one or both eyes if they press directly on the optic nerves.

What is Sellar region?

The sellar region is a tiny anatomic compartment in which many lesions and developmental diseases can be found. 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.

What does Suprasellar mean?

: situated or rising above the sella turcica —used chiefly of tumors of the pituitary gland.

What is Suprasellar extension?

The sphenoid sinus is known to have a variable anatomical configuration, and the authors hypothesize that certain anatomical factors may resist tumor expansion into the sphenoid sinus, thereby directing tumor growth into the suprasellar space.

How big is the Sellar and suprasellar meningioma?

It is T1 and T2 isointense to brain grey matter and exhibits vivid homogeneous contrast enhancement. It measures about 3.3 x 3.5 cm in axial and 6.5 cm in CC diameters. It extends superiorly more to the left, elevating and compressing the optic chiasma and hypothalamus as well as the left lateral ventricle and splaying the interpedunclar cistern.

Who are the doctors that treat suprasellar meningiomas?

Mount Sinai Health System and its team of fellowship-trained skull base surgeons, led by Joshua Bederson, MD, specializes in diagnosis and treatment of suprasellar meningiomas, a tumor that develops between the two optic nerves. We are a major referral center in the tri-state area and home to the Pituitary Care and Research Center.

How is the meningioma of the tuberculum Sella characterized?

Well defined suprasellar solid mass seen which shows homogenous enhancement and a broad dural attachment to the planum sphenoidale. Note that the diaphragma sellae is not “pushed up” as it would have been with a macroadenoma, but rather is depressed, indicating this mass is of suprasellar origin.

How is a meningioma related to a brain tumor?

A meningioma is a tumor that arises from the meninges — the membranes that surround your brain and spinal cord. Although not technically a brain tumor, it is included in this category because it may compress or squeeze the adjacent brain, nerves and vessels.
