Where is a tuberculum sellae meningioma?
Tuberculum sellae meningiomas (TSMs) arise from the tuberculum sellae, a bony structure along the midline skull base located just anterior and inferior to the optic chiasm. It is flanked by the optic chiasm and optic nerves, carotid arteries, the cavernous sinus, pituitary gland, and sphenoid sinus.
What is tuberculum sellae 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 the tuberculum sellae?
The tuberculum sellae forms the anterior wall of the sella turcica, which houses the pituitary gland. It is an elongated ridge located immediately posterior to the chiasmatic groove, hence is related to the optic chiasm and anterior portions of the optic tracts.
Where is the dorsum sellae?

Where is sella turcica located?
The sella turcica is a saddle-shaped depression located in the bone at the base of skull (sphenoid bone), in which resides the pituitary gland.
Which gland is located in the sella turcica?
The pituitary gland
The pituitary gland is within the sella turcica or the hypophyseal fossa. This structure is present near the center at the base of the cranium and is fibro-osseous. The anatomical boundaries of the gland have clinical and surgical significance. Sella turcica is a concave indentation in the sphenoid bone.
What is Rostrally and Caudally?

Where is the dorsum located?
back
