These symptoms are actually signs of a recurrence of keratinous brain tumor!

Corneal brain tumor is also a common brain tumor. Medically, tumors that grow in the skull are collectively referred to as brain tumors. The causes of brain tumors are quite complex, and clinically, even if they receive timely and regular treatment, they are prone to recurrence. The following symptoms are actually signs of brain tumor recurrence!

1. Headache

Direct compression or pulling of local pain-sensitive structures by the tumor can cause localized headaches with localized extracranial tenderness. Headaches are usually paroxysmal, with swelling or throbbing pains, and often occur at night and in the early morning. As the tumor gradually grows, it eventually becomes persistent. When the intracranial pressure increases, the headaches tend to be widespread.

2. Visual impairment

The optic nerve head becomes edematous due to the obstruction of retinal venous blood flow caused by increased intracranial pressure. The symptoms include loss of visual field and enlarged blind spot.

3. Severe vomiting

Headaches are often preceded by nausea and vomiting, which is caused by stimulation of the vagus nerve center in the medulla oblongata. It usually occurs at night or in the morning on an empty stomach or when the location of the headache changes. Vomiting is more common in infratentorial tumors than in supratentorial tumors. Vomiting is often the only symptom of cerebellar tumors in children.

4. Epileptic convulsions

Generalized epileptic seizures may be related to increased intracranial pressure, but they may also be the local effects of a brain tumor.

5. Dizziness

Vertigo caused by increased intracranial pressure is not a feeling of spinning, but more commonly a feeling of instability and a tendency to fall when bending over.

6. Psychiatric symptoms

In mild cases, the main symptoms may be only memory loss and decreased concentration, and easy irritation. When the intracranial pressure increases slowly, it can lead to progressive dementia, and the patient has intellectual decline, apathy, and incontinence. When the intracranial pressure increases acutely or subacutely, it often causes mental confusion. When the pressure rises to a very high level, all mental activities of the patient almost stop and fall into a coma.
