Table 2 Proposed classification of hydrocephalus
From: The definition and classification of hydrocephalus: a personal recommendation to stimulate debate
Site of Obstruction | Pathology | Treatment |
|---|---|---|
None | Choroid plexus papilloma | Removal |
Foramen of Monro | Tumor, congenital anomaly, postshunt ventricular asymmetry | Tumor removal, septum pellucidotomy, ventricle shunt |
Aqueduct of Sylvius | Congenital lesion, tumor secondary to extraventricular obstruction | ETV, ventricular shunting |
Outlets of fourth ventricle | Chronic meningitis, Chiari II malformation | ETV, ventricular shunting |
Basal cisterns | Meningitis, post subarachnoid hemorrhage | ETV, ventricle shunt, spinal thecal shunt |
Arachnoid granulations | Hemorrhage or infection in infancy | Ventricle or thecal shunt |
Venous outflow | Skull base anomalies, congenital heart disease | Ventricle or thecal shunt, treatment of vascular anomaly if possible |
