In non-communicating hydrocephalus (HC), enlarged cerebral ventricles are often thought to reflect increased intracranial pressure (ICP) or increased pulsatile ICP. The present study was undertaken to explore the association between ventricular volume measures and pulsatile or static ICP scores in patients with non-communicating HC. Since linear measures of ventricular size have the most widespread use, we also examined how linear and volume measures of ventricular size compare. ⋯ In this cohort of patients with non-communicating HC, we found no evidence of a proportional correlation between ventricular volume and pulsatile or static ICP. However, the findings suggest that symptomatic and untreated non-communication HC is still associated with reduced intracranial compliance.
