How are brain tumors identified?

MRI , then biopsy: Usually patinets present with new neurologic symptom. Seizure, headache, nausea, vometing, stroke like symptoms next imaging usually a MRI scan is obtained biopsy confirms pathologic diagnosis.

See below: Might be tough if no biopsy and microscopic pathology. Yet location might help, as might MRI characteristics. Meningioma seems to be peripheral at the coverings of the brain. Childhood glioma may be central brainstem. Gliobastoma multiforme varies in appearance and texture on the mri. A metastasis may be surrounded with a ring of swelling (edema). Gold standard, a piece of the tumor to diag.

Imaging & pathology: As others have noted the first step to finding a brain tumor is an imaging study such as ct or mri. The former is faster and cheaper but may miss small tumors. Once a tumor is found, a tissue diagnosis is needed, either open surgery or biopsy. This would require a neurosurgeon to tell you what is best.
