In short

Medulloblastoma- Classic symptoms of increased ICP include irritability, lethargy, nausea and vomiting, morning headaches, anorexia, and behavioral changes.

The most widely available tracer, FDG, is a predictor of prognosis and is particularly useful for distinction of brain lymphoma from nonmalignant lesions.

About 33% of all brain tumors are gliomas, accounting for about 80% of the total malignant central nervous system (CNS) tumors in adults. GBM remains associated with an extremely aggressive clinical course, and only 0.05–4.7% of patients survive 5 years from diagnosis.

Currently, the standard of care for brain tumors consists of surgical resection followed by radiotherapy (RT) and concomitant and adjuvant chemotherapy.
