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 Planum sphenoidale meningioma?

Planum sphenoidale meningiomas are extra-axial slow-growing tumors arising from the roof of the sphenoid sinus and the area between the optic nerves and the anterior clinoid processes. Enlargement of this meningiomas usually pushes the optic nerves dorsally and caudally causing vision loss as a primary manifestation.

What is olfactory groove meningioma?

Olfactory groove meningiomas grow along the nerves that run between the brain and the nose, the nerves allow you to smell. They can become large without causing significant neurologic deficits or evidence of increased intracranial pressure. Loss of smell can often be the only symptom.

What is the sphenoid wing?

Sphenoid wing meningiomas are slow growing tumors that originate from outer arachnoid meningeal epithelial cells. They are the most common tumor of the intracranial space to spread to the orbit.

What is a tuberculum?

(ˈtjuːbəkəl ) or tuberculum (tjʊˈbɜːkjʊləm) noun. any small rounded nodule or elevation, esp on the skin, on a bone, or on a plant. any small rounded pathological lesion of the tissues, esp one characteristic of tuberculosis. Word origin.

Where is a Tuberculum Sellae meningioma?

Tuberculum sellae meningiomas very commonly extend into both optic canals, a problem that is underemphasised in published reports. Visual loss in one eye with optic atrophy is the initial and most common symptom. These tumours tend to displace the optic chiasm backwards and the optic nerves laterally and superiorly.

How long can you live with a benign meningioma?

Currently, more than 90 percent of adults between the ages of 20 and 44 survive for five years or longer after being diagnosed with meningioma. This encouraging survival rate includes many patients who have gone on to live several decades after their diagnosis.

Is a meningioma serious?

Although the majority of meningiomas are benign, these tumors can grow slowly until they are very large, if left undiscovered, and, in some locations, can be severely disabling and life-threatening. Other forms of meningioma may be more aggressive.

Can a brain tumor affect your smell and taste?

a brain tumour in the parietal lobe could lead to difficulty bringing together information from your senses, including smell and taste (as well as other symptoms, such as, difficulty recognising faces or objects and coordinating movements).

What are the symptoms of an olfactory groove meningioma?

If you have an olfactory groove meningioma, you probably will not experience any symptoms until the tumor grows to a large size. Tumors in this location may cause symptoms such as loss of smell and taste, blurred vision, memory loss, headaches, fatigue, nausea and vomiting, and personality changes.

What is sphenoid wing dysplasia?

Sphenoid wing dysplasia is a defining feature of neurofibromatosis type 1 (NF1). This defect of the skull base can be associated with pulsating exophthalmos.

Can a meningioma cause loss of taste?

What is the planum sphenoidale?

The planum sphenoidale is a common term for the anterior horizontal part of the superior surface of the body of the sphenoid bone. It is known in the Terminologia Anatomica (2019) as the jugum sphenoideum or sphenoidal yoke 1. It forms part of the anterior skull base, separating the anterior cranial fossa from the sphenoid sinuses.

Is there a new surgical technique for Planum sphenoidale meningiomas?

-OBJECTIVES: We report a modern surgical technique specific for planum sphenoidale and tuberculum sellae meningiomas with associated outcome. A new classifica- tion system that can guide the surgical approach and may predict surgical risk is proposed.

What is the jugum sphenoideum?

It is known in the Terminologia Anatomica (2019) as the jugum sphenoideum or sphenoidal yoke 1. It forms part of the anterior skull base, separating the anterior cranial fossa from the sphenoid sinuses. Posteriorly, the structure terminates as the limbus sphenoidale and borders the chiasmatic sulcus 2,3.
