What are the examination methods for pituitary tumors

Pituitary tumors are a disease that has a certain incidence rate now. It is not a new word for everyone. Some couples are even diagnosed with infertility caused by pituitary tumors during obstetric examinations. I believe that there is no need to say more about how harmful it is. If symptoms of pituitary tumors appear, they should be checked and diagnosed as soon as possible. So, what are the examination methods for pituitary tumors?

The examination items for pituitary tumors are as follows:

1. Understand the symptoms:

The symptoms of pituitary tumors are the primary factor in determining the condition. The main symptoms of pituitary tumors are often manifested as decreased vision, lactation in women, sexual dysfunction in men, etc. If these symptoms appear, further examinations should be done to confirm the condition.

2. CT scan examination:

CT has certain value in diagnosing pituitary tumors, but also has certain limitations. The density of pituitary tumor masses is slightly higher than that of brain matter, and the surrounding brain pools and ventricles contain low-density cerebrospinal fluid, which can all be detected by CT scans. Intravenous infusion of iodinated contrast agents can enhance tumor density and improve the detection rate of tumors.

3. Magnetic resonance imaging:

The normal pituitary tissue disappeared, replaced by a soft tissue mass about 2×3 cm in size. The sellar diaphragm was bulging, the optic chiasm was compressed, the sellar floor was sunken, and one side of the cavernous sinus was invaded.

4. Skull plain film and layered radiography:

Pituitary tumors grow within the sella turcica. In the early stage, if the tumor is small, it does not affect the sella turcica. After that, the tumor continues to grow, causing mild localized bone changes. On thin-layer slices, a small section of the sella turcica bone wall can be found to be slightly bulging, absorbed or destroyed. Subsequently, it presents a typical space-occupying change within the sella turcica. The anterior-posterior diameter, deep diameter, wide diameter and volume of the sella turcica exceed normal, and the sella turcica enlarges to a cup shape, spherical or flat shape. If it grows to the side of the sella turcica, it presents a parasellar space-occupying change, and the sella turcica bottom presents a double contour. If the tumor is huge, it can destroy the sella turcica back and the sella turcica bottom.

The above is an introduction to the examination methods of pituitary tumors. I hope it will be helpful to you.
