Is a Suprasellar mass a tumor?

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.

How can you tell the difference between pituitary adenoma and craniopharyngioma?

However, pituitary adenomas and craniopharyngiomas differ from each other, as follows: 1) pituitary adenomas are the third most common type of intracranial tumor and represent a significant proportion of brain tumors affecting humans and approximately 80% of sellar lesions, whereas craniopharyngiomas represent only 1 …

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 does Parasellar mean?

Abstract. 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.

Does stress cause pituitary tumors?

There are reliable research studies showing severe stress, childhood trauma, and/or physical trauma increase the likelihood of the development of a pituitary tumor.

What is Suprasellar Germinoma?

Background: Germinomas are rare malignant central nervous system tumors, a type of germ cell tumor, according to the 2016 World Health Organization Classification of Brain Tumors. Most of these tumors develop along the midline, most often from the pineal gland, followed by tumors arising in the suprasellar cisterns.

How is a suprasellar mass diagnosed?

Suprasellar masses: diagnosis and differential diagnosis Suprasellar masses are neoplastic, vascular, congenital, or infectious/inflammatory in origin. Magnetic resonance imaging (MRI) is the study of choice for evaluating suprasellar masses, although computed tomography (CT) may provide complementary information.

What are some examples of suprasellar masses?

A simple and popular mnemonic to remember the common suprasellar/parasellar/intrasellar masses is SATCHMO. The more comprehensive list includes: tumors pituitary adenoma (commonest in the adult population) pituitary macroadenoma. pituitary microadenoma. pituitary carcinoma. pituitary lymphoma. meningioma. craniopharyngioma.

What is MR imaging of the Sellar and juxtasellar regions?

MR imaging of the sellar and juxtasellar regions. Multiplanar capability and superior tissue contrast differentiation render magnetic resonance (MR) imaging the preferred method for examining patients with pituitary axis dysfunction or visual field deficits.

What is the differential for suprasellar cystic lesions?

The differential for suprasellar cystic lesions is large and predominantly includes developmental and neoplastic conditions. 1. Saleem SN, Said AH, Lee DH. Lesions of the hypothalamus: MR imaging diagnostic features.
