Prior Study
T2-w spin-echo or noncontrast T1-w MR, noncontrast CT with scout skull image1. Evidence of chronic raised intracranial pressure related to advanced slowly progressive hydrocephalus caused by partial block of CSF egress from tectal dysplasia and from developmentally small posterior fossa compressing the 4th ventricular outlets.
2. Calvarial changes of chronic raised ICP on the scout for CT with split cranial sutures and remodeling and enlargement of the sella turcica.
3. Mulitcentric developmental dysmorphic changes including aqueductal stenosis , cortical migrational abnormalities, and hypoplasia of the clivus and posterior fossa.
