Expanded cavum septi pellucidi and cavum vergae associated with behavioral symptoms relieved by a stereotactic procedure: Case report

Cavum septum pellucidum cyst in children: a case-based update

“…It seems that a basic factor of symptomatic CSP cyst is that it is noncommunicating [17,21,25]. However, the proof of communication with the ventricular system is difficult in routine neuroimaging studies [10].…”

“…Regularly, mental status changes were associated to symptoms or signs of increased ICP, except in three cases. In the first, the child presented with convulsions [8], in the second case, there was gait ataxia, paraparesis, and hydrocephalus, and in the last one, there was also an "unstable gait" [21].…”

Symptomatic Cysts of the Cavum Septi Pellucidi and Cavum Vergae: The Role of Endoscopic Neurosurgery in the Treatment of Four Consecutive Cases

“…As a consequence of the many important anatomic structures lying within or immediately adjacent to this triangle, the symptoms as a result of mass effect in this region vary. Behavioural, autonomic and sensorimotor disturbances may be present and include mental status changes, memory impairment, emotional labiality, bizarre behaviour, epileptic seizures, frontal ataxia and hemisensory impairment [3,27,32,36,37,45]. There is clearly a need for surgery in symptomatic septum pellucidum cysts.…”

“…Nevertheless, placement of cystoperitoneal shunt in patients, without having hydrocephalus, may result in the syndrome of CSF overdrainage [26,28]. Alternatively, stereotactic techniques are less invasive than craniotomy and may be performed with a variety of image- guided strategies [5,25,32,33,44]. Despite the advantages of stereotactic procedures compared with craniotomy, there is an important limitation.…”

Endoscopic Fenestration of Symptomatic Septum Pellucidum Cysts: Three Case Reports with Discussion on the Approaches and Technique

“…Since Dandy [4] realized the first cyst excision by craniotomy, symptomatic cysts of the septum pellucidum have been treated with different techniques, including fenestration of the cyst wall in the ventricular system by a direct approach [1,10,11,13,24], punction of the cyst through a burr hole under radiographic control [18] or by stereotactic approach [2,5,14,19,23], and shunting of the cyst into the peritoneum [3,7]. Endoscopy is a relatively recent and more appropriate surgical technique which consents to fenestrate the cyst into the ventricular system.…”
