How can you determine the location of the sella turcica?

Structure. 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 anatomical part is located in the sella turcica?

Introduction: The sphenoid bone has a superior depression called the sella turcica, Latin for “Turkish saddle,” where the pituitary gland is found.

What is located in the sella turcica?

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.

Where is the pituitary gland on a CT scan?

Gross anatomy. The pituitary gland sits atop the base of the skull in a concavity within the sphenoid bone called the sella turcica (pituitary fossa), immediately below the hypothalamus and optic chiasm.

What are the causes of widening of sella turcica?

Enlargement of sella turcica can be seen in situations including the following:

empty sella syndrome.
intracranial hypertension.
pituitary tumors (e.g. macroadenoma)
craniopharyngioma.
Rathke’s cleft cyst: rarely can cause sellar enlargement if reaches large size 2

What neural structure is found in the sella turcica and what are its main functions?

Brain and Spinal Cord Empty sella is a disorder involving the presence of CSF within the cavity of the sella turcica, the saddle-shaped structure that houses the pituitary gland.

Is the sella turcica visible using medical imaging?

The magnetic resonance image shows that the sella turcica is extremely shallow. The pituitary gland is situated in the suprasellar cistern but otherwise appears normal in morphology and is easily recognized on the sagittal images because of the characteristic high signal intensity in the posterior lobe.

What is the sella turcica where is located Why is important?

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.

Can a CT scan miss a pituitary tumor?

CT scans can find a pituitary adenoma if it’s large enough, but MRI scans are used much more often to look at the brain and pituitary gland.

What blood test shows pituitary tumor?

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) blood levels can be checked to see if you have a gonadotropin-secreting tumor. Levels of related hormones, such as estrogen, progesterone, and testosterone, are often checked as well.
