Stenosis of the Aqueduct of Sylvius

Aqueduct stenosis. Case review and discussion.

“…A valvular action could also explain the relapsing and remitting course of our case 21 who went through several critical periods of high pressure, the last of which was fatal. Similar periodicity was noted by Beckett et al (1950) andPennybacker (1940), and sudden unexpected death by Parker and Kernohan (1933). In the hydrocephalic process other cavities develop (Figs 1 and 2), and enlargement of the third ventricle results in extensions such as an enlarged suprapineal recess.…”

Effect of endoscopic third ventriculostomy on neuropsychological outcome in late onset idiopathic aqueduct stenosis: a prospective study

“…[1][2][3][4][5][6][7] In the adult, the idiopathic variant with a late onset has recently been termed LIAS (late onset idiopathic aqueductal stenosis). [8][9][10][11] With the reinvention of cerebral endoscopy during the latter decades, the treatment of LIAS has been changed from shunt implantation to endoscopic third ventriculostomy.…”

Forking of the Aqueduct in an Adult

“…An angiomatous malformation of the Sylvian aqueduct with occlusion has been reported (GRAF 1946). Occlusion from pressure by an intracranial tumor is another possibility (PARKER & KERNOHAN 1933, PENNYBACKER 1940 as well as pressure from a tentorial herniation.…”
