What examination should children craniopharyngioma do?

summary

In recent years, with the increasing of diseases, children's growth and development has been greatly harmed, especially craniopharyngioma, which has a higher incidence. Experts point out that when children suffer from this disease, they must go to professional and regular hospitals for treatment. So, what examination should children craniopharyngioma do? Now let's talk about it.

What examination should children craniopharyngioma do?

Brain CT scan showed sellar region tumor changes. Non enhanced scan showed high-density or equal density image of solid tumor, high-density calcification spot, low-density image of cystic tumor due to cholesterol content, CT value was - 40 ~ 10hu, and equal density image of cyst wall. The lesions were round, oval or lobulated with enlarged lateral ventricles. About 2 / 3 of the cases had different degrees of enhancement. The CT value increased by 12-14 Hu. Cystic craniopharyngiomas showed ring enhancement or multiple ring enhancement, but there was no enhancement in the central low-density area, and a few craniopharyngiomas did not. Generally, tumors in sellar region with calcification, cystic cavity and enhancement after enhancement can be diagnosed as craniopharyngioma.

Most of the cystic parts of craniopharyngiomas have short T1 and long T2 images, but they can also have long T1 and long T2 images, that is, low signal on T1 weighted images and high signal on T2 weighted images; If it is a solid craniopharyngioma, it shows long T1 and long T2. Calcified spots were low signal areas. CT and MRI examination are of great significance in diagnosis. These two examinations can show the location, size, cystic change, invasion of tumor to adjacent brain tissue, and hydrocephalus of the tumor. Generally speaking, MRI is superior to CT in showing the structure of the tumor and its relationship with adjacent brain tissues (such as optic chiasm), but it can not show calcification like CT.

Because of the different size of tumors, ventriculography can clearly show the impact and changes of tumors on the basilar artery, which is very helpful for surgery. Whether the cystic cavity of the tumor is connected with the ventricle can be directly punctured into the cystic cavity of the tumor at the same time of ventriculography.

matters needing attention

Craniopharyngioma mostly occurs in children and young people, their psychological endurance is poor, once diagnosed, psychological burden is very heavy, easy to produce fear, pessimism. In addition, craniotomy has certain risks, patients often feel uneasy, afraid and irritable, affect rest and sleep, and even refuse surgery.
