Distinctive CT appearance of cyst of the cavum septi pellucidi

Cyst of the Septum Pellucidum and Korsakoff’s Psychosis

“…Wide opening and intraventricular drainage of the cyst is generally sufficient therapy [5], and in our case it led to a progressive and complete recovery.…”

“…CT scan is helpful in the investigation of these lesions without the need for further invasive neuroradiological studies [5]. The distinctive features and limitations of the CT scan are well known [5,12].…”

“…The distinctive features and limitations of the CT scan are well known [5,12]. Differential diagno sis should be established with other fluid-filling midline cysts, mainly of the third ventricle.…”

Cavum septum pellucidum and obstructive hydrocephalus.

“…[7][8][9][10][11] We have described five patients with symptoms of persistent or intermittent obstructive hydrocephalus associated with an enlarged cavum septum pellucidum. The most common presenting symptoms were intermittent headache (all four adult cases) and loss of consciousness (three of the four adult cases), presumably due to sudden transient obstruction of the foramina of Monro.…”

MR and CT of Brain's Cava

“…The “communicating” one is thought to be entirely asymptomatic. Rare noncommunicating cysts infrequently become large enough to obstruct the foramen of Monro 10 . The prevalence of this condition is quite rare 11 and intraventricular drainage of the cyst is generally sufficient therapy 10 .…”
