X-Ray: Pituitary fossa or sella turcica

Specimen Required

NONE

Fasting Required

Purpose of the Test

An X-ray of the pituitary fossa or sella turcica may be performed to evaluate the size and shape of the pituitary gland and surrounding structures, such as the optic chiasm and brainstem. It can help diagnose conditions such as pituitary tumors, empty sella syndrome, and other abnormalities in this region.

When this test is required

A pituitary fossa or sella turcica X-ray may be requested if a doctor suspects a pituitary gland disorder, such as a tumor or other growth. It may also be ordered if a person is experiencing symptoms such as headaches, vision problems, or hormonal imbalances.

What the Test Detects

An X-ray of the pituitary fossa or sella turcica is an imaging test that uses X-rays to produce images of the pituitary gland and surrounding structures, such as the optic chiasm and brainstem.

Preparation for the Test

No specific preparation is required for a pituitary fossa or sella turcica X-ray. The person may be asked to remove any clothing or jewelry that may interfere with the X-ray examination.

Sample Requirements

No sample is required for a pituitary fossa or sella turcica X-ray. The test is non-invasive and involves only the use of X-rays.

Additional Notes

An X-ray of the pituitary fossa or sella turcica involves exposure to radiation, which can increase the risk of cancer. However, the amount of radiation used in this type of X-ray is generally considered to be safe. The risks and benefits of the test should be discussed with a doctor before the examination is performed. It is also important to note that an X-ray is not always able to detect all abnormalities or conditions affecting the pituitary gland or surrounding structures, and additional testing may be required if there is still concern.
