Where is a Suprasellar mass located?
Suprasellar masses present with a variety of neurologic or endocrine dysfunctions depending on their site of origin and mass effect on adjacent structures. The suprasellar cistern is a cerebrospinal fluid filled space between the top of the pituitary and bottom of the hypothalamus.
What is Suprasellar disease?
Brain and Skull Base Tumors Parasellar tumors are growths near the part of the brain known as the sella turcica. The most common surgical treatments for parasellar tumors are craniotomy and transsphenoidal surgery; the nonsurgical treatment is stereotactic radiosurgery.
What is Sellar and 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 are the symptoms of a tumor on your pituitary gland?
Signs and symptoms include:
- Nausea and vomiting.
- Weakness.
- Feeling cold.
- Less frequent or no menstrual periods.
- Sexual dysfunction.
- Increased amount of urine.
- Unintended weight loss or gain.
What is a Sellar tumor?
Neoplasms of the sellar region include pituitary adenomas, craniopharyngiomas, Rathke’s cleft cysts, and, less commonly, meningiomas, germinomas, and hamartomas. Each of these entities has unique diagnostic and treatment considerations.
What is a Sella tumor?
Pituitary adenomas. These benign tumors do not spread outside the skull. They usually stay in the sella turcica (the tiny space in the skull that the pituitary gland sits in). Sometimes they grow into the boney walls of the sella turcica and nearby tissues, like blood vessels, nerves, and sinuses.
What is Sellar tumor?
Abstract. Neoplasms of the sellar region include pituitary adenomas, craniopharyngiomas, Rathke’s cleft cysts, and, less commonly, meningiomas, germinomas, and hamartomas. Each of these entities has unique diagnostic and treatment considerations.
Do pituitary tumors need to be removed?
Surgical removal of a pituitary tumor usually is necessary if the tumor is pressing on the optic nerves or if the tumor is overproducing certain hormones. The success of surgery depends on the tumor type, its location, its size and whether the tumor has invaded surrounding tissues.
What makes a brain tumour inoperable?
Inoperable tumors are those located in an inaccessible place in the brain , or those that are composed of multiple tumors that cannot all be removed . Surgeons cannot always access every corner of the brain, and there may be some concern about damaging nearby tissues.
How does a brain tumour affect the brain?
Brain tumors can be cancerous (malignant) or noncancerous (benign). When benign or malignant tumors grow, they can cause the pressure inside your skull to increase. This can cause brain damage , and it can be life-threatening. Brain tumors are categorized as primary or secondary. A primary brain tumor originates in your brain.
What is a brain tumour?
A brain tumour is a mass, or lump in the brain which is caused when brain cells divide and grow in an uncontrolled way. What causes brain cells to start growing and dividing differently from healthy cells, forming a high grade (cancerous) or low grade ( benign) tumour is not yet understood. There are…
What is lipoma in brain?
A lipoma is a piece of fatty tissue in the brain. It is not a malignant tumor. It normally has been in the brain for an extended time, and is discovered because of an MRI or CT scan given for neurological symptoms. It is very difficult to know if your symptoms are related to the lipoma.
