This tumor can affect nerve structures near the hypothalamus, including the optic nerves, optic chiasms, and other important areas.

Gradual deterioration of vision, usually in one or both eyes, is one of the most characteristic symptoms. This is due to the pressure of the tumor on the optic nerves or optic chiasms.

As the tumor expands, it can put pressure on the hypothalamus, which can cause endocrine disruptions such as growth disorders, menstrual irregularities, and diabetes.

A chiasmatic glioma can affect neighboring structures and cause focal disturbances and balance. Recurrent or persistent headaches may be one of the symptoms of chiasmatic glioma.

Diagnosis at MDI Clinic

Diagnostic measures of the disease require a comprehensive and multilevel approach. It is important to perform all necessary tests to accurately identify the tumor, its characteristics, and its spread.

The physician performs a general physical examination, including an evaluation of the patient’s vision and neurological condition. He also takes a history to find out the symptoms, duration and nature of the disease, and the presence of risk factors.

Magnetic resonance brain imaging is the primary method of diagnosing chiasmatic glioma. It is a safe study that provides detailed 3D images of the brain and determines the size, location and nature of the tumor. MRI can also be used to evaluate neighboring structures such as optic nerves and chiasma.

Electroencephalography can be performed to assess the electrical activity of the brain. This can help identify epileptic activity that may result from tumor pressure on nerve structures.

Sometimes, a biopsy may be needed to determine the exact type of tumor. In this case, a small tissue sample from the tumor is taken surgically and then analyzed at the cellular and molecular level.
