What is found in the hypophyseal fossa of sella turcica?

What is found in the hypophyseal fossa of sella turcica?

The sella turcica is located in the sphenoid bone behind the chiasmatic groove and the tuberculum sellae. It belongs to the middle cranial fossa. The sella turcica’s most inferior portion is known as the hypophyseal fossa (the “seat of the saddle”), and contains the pituitary gland (hypophysis).

What is the difference between sella turcica and hypophyseal fossa?

The sella turcica is a saddle-shaped depression in the midline of the sphenoid sinus at the skull base and is the caudal aspect of the hypophyseal fossa, which contains the pituitary gland. The degree of pneumatization of the sphenoid sinus can vary.

What is the sella turcica and where is it 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.

What is the significance of the sella turcica?

During embryological development, the sella turcica area is the key point for the migration of the neural crest cells to the frontonasal and maxillary developmental fields. The neural crest cells are involved in the formation and development of sella turcica and teeth.

What is MRI sella?

This compartment is called the sella. When the pituitary gland shrinks or becomes flattened, it cannot be seen on an MRI scan. This makes the area of the pituitary gland look like an “empty sella.” But the sella is not actually empty. It is often filled with cerebrospinal fluid (CSF).

Why do an MRI of the pituitary gland?

An MRI produces good soft-tissue images and allows the physician to evaluate different types of body tissue, as well as distinguish normal, healthy tissue from diseased tissue. Our team of specialist physicians will use these images to make a detailed study of your pituitary gland and to find possible problems.

What part of the brain sits in the sella turcica?

Empty sella syndrome (ESS) may occur if you have an enlarged sella turcica. This is a bony structure where the pituitary gland sits at the base of the brain.

What is MRI pituitary fossa?

A pituitary MRI (magnetic resonance imaging) is an imaging test that makes pictures of the pituitary gland (small gland in the brain that controls hormones and other glands in the body) and surrounding areas in the brain.

What causes enlarged sella turcica?

ESS may happen if you have an enlarged sella turcica. This is a bony structure where the pituitary gland sits at the base of the brain. Health experts don’t know what causes primary ESS. Secondary ESS may be caused by injury, radiation therapy, or surgery.
