LIAS patients' series. According to Fukuhara and Luciano (2001), patients were divided in three classes according to hydrocephalus duration. Class I (acute): symptoms lasting less than 1 month. Class II (subacute): 1 month <, < 6 months. Class III (chronic): more than 6 months. +: no flow through aqueduct of Sylvius. Not done: patients underwent a brain MRI with sagittal T1 and T2 weighted images which documented a stenosis of the aqueduct of Sylvius, LIAS: late-onset idiopathic aqueductal stenosis, MRI: magnetic resonance imaging.
