Overview
TNM Classification of Medulloblastoma
T: Primary Tumor
| T | Description |
| TX | Primary tumor cannot be assessed |
| T0 | There is no evidence of primary tumor |
| T1 | Tumor size <3 cm in diameter |
| T2 | Tumor size ≥3 cm in diameter with no evidence of extension |
| T3a | Tumor size >3 cm in diameter with extension into aqueduct of Sylvius or foramen of Luschka |
| T3b | Tumor size >3 cm in diameter with definite spread into the brain stem |
| T4 | Tumor size >3 cm in diameter with extension past aqueduct of Sylvius or down past foramen magnum |
N:Regional Lymph Nodes
M: Distant Metastasis
