What causes pituitary Microadenoma?

What causes pituitary Microadenoma?

Pituitary microadenomas develop when DNA mutations cause cells in the pituitary gland grow and divide uncontrollably. Experts are not entirely sure what causes these genetic mutations to happen. A small percentage of pituitary tumors run in families, but most cases do not have any obvious hereditary factor.

What is Parasellar meningioma?

Conclusion. Parasellar meningiomas remain mostly benign tumors with WHO grade I and a meningothelial subtype. Progestin intake should be investigated. The therapeutic strategy should be adapted to the tumor location and growth.

How do you treat a Microadenoma?

In most cases, a microadenoma can be cured with endoscopic transsphenoidal surgery. In this procedure, a neurosurgeon reaches the tumor through the nasal passages and sphenoid sinus. Gamma Knife radiosurgery, which uses targeted beams of radiation to destroy the tumor, is another option.

What is a Parasellar mass?

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.

How serious is a pituitary Microadenoma?

They are found in about 77 out of 100,000 people, although it is believed that they actually occur in as many as 20% of people at some point in their lives. However, many pituitary adenomas, especially microadenomas, do not cause serious symptoms and are never found.

Where is the Parasellar region?

The parasellar region, located around the sella turcica, is an anatomically complex area representing a crossroads for important adjacent structures. Several lesions, including tumoral, inflammatory vascular, and infectious diseases may affect this area.

How effective is gamma knife for meningioma?

Gamma Knife treatment successfully treats 90 to 95 percent of meningioma patients, typically with just one treatment.

Are Microadenomas serious?

What is sella and Parasellar?

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.
