How to diagnose optic glioma?

summary

Optic gliomas are benign tumors occurring in the glial cells of the optic nerve, which can spread to the brain along the optic nerve. Most of them occurred in preschool children, but rarely in adults. Some of them were associated with neurofibromatosis. It is suspected that they have genetic tendency. The prognosis is better than that of intracranial glioma. How to diagnose optic glioma? Let's talk about it

How to diagnose optic glioma?

Adults are prone to hair loss and slow vision loss. Imaging can find the optic nerve thickening, shape diversity, such as tubular, fusiform, conical, beaded, lumpy or irregular shape. Because the tumor originated from the optic nerve sheath, the "vehicle track sign" could be seen on CT and MRI.

Most of them were in childhood. The nonfunctional microphthalmos often disappeared under the eyelid, and the abnormal development of eyeball was found under slit lamp. The cyst protrudes forward and causes periorbital protrusion. The cystic mass behind the microphthalmos can be found by imaging, which is round, oval or conical.

The symptoms of inflammation such as eye pain and conjunctival congestion were obvious, and hormone therapy was effective. Imaging can find the irregular shape around the optic nerve occupying space, the boundary is not clear, forward development around the eyeball, showing "casting sign".

matters needing attention

Patients should be given anti-tumor food, such as wheat, Coix, water chestnut, jellyfish, asparagus, kelp. It is suitable to eat foods with the effect of preventing and controlling intracranial hypertension, such as corn whisker, red bean, walnut kernel, laver, carp, duck, Ulva lactuca, kelp, crab and clam. Patients diet avoid spicy food, such as onion, garlic, leek, pepper, pepper, cinnamon and so on.
