Putative theories to explain elevated ICP in PTCa
| Proximal Etiology | Result |
|---|---|
| Increased interstitial fluid (ISF) volume | Increased cerebral volume |
| Increased blood volume | |
| Increased tissue volume | |
| Increased CSF production rate | Increased CSF volume |
| Increased CSF outflow resistance | |
| Loss of cerebral autoregulation | Increased cerebral arterial pressure |
| Increased cerebral venous pressure | Increased venous blood volume and increased ISF |
| Reduced CSF outflow and increased CSF volume |
