Intracranial Neoplus Research Paper

It depends on the site of the tumor, biological behavior and aggressiveness of the tumor, and the rate of growth. At the time of presentation, the patient may be very ill from severe headache or frequent vomiting due to associated hydrocephalus. Presenting complaints of patients with an intracranial neoplasm tend to be similar for primary brain tumors and intracranial metastases. The onset of symptoms usually is insidious, but an acute episode may occur with bleeding into the tumor, or when an intraventricular tumor suddenly occludes the third ventricle.
Symptoms may be caused by focal compression of the cerebellum or brain stem centers and increased intracranial pressure. Symptoms due to focal brainstem compression include cranial nerve dysfunction.
