Cavum veli interpositi is an open CSF space in the roof of the third ventricle that surrounds the internal cerebral veins, and is a forward extension of the quadrigeminal plate cistern. To the best of our knowledge, spontaneous resolution of a cavum veli interpositi has not been reported in the literature to date. Interestingly, case reports of spontaneous resolution of cystic cavum septum pellucidum in three patients and eighteen arachnoid cyst cases has been described in the literature. We describe the spontaneous resolution of a cavum veli interpositi or cyst in cavum veli interpositi in a 35-year-old man and review the literature of spontaneous resolution of cavum septum pellucidum and arachnoid cysts.

The Brain

Lesions in the pineal region are topographically located in the centre of the brain in the diencephalic-epithalamic region. An area where the brain is bounded ventrally by the quadrigeminal plate, midbrain tectum, and in-between the left and right superior colliculi, dorsally by the splenium of the corpus callosum, caudally by the cerebellar vermis and rostrally by the posterior aspects of the third ventricle. Major anatomical and surgical challenges are the vein of Galen located dorsally, the precentral cerebellar vein caudally, the internal cerebral veins anteriorly and the basal vein of Rosenthal laterally. Most pineal region tumours can be safely removed by both approaches depending on the surgeon’s experience: the occipital transtentorial approach is recommended in presence of associated hydrocephalus or a steep straight sinus and low location of the tumour and the supracerebellar infratentorial approach for posterior third ventricle tumours.

Endoscopic Fenestration

Abstract BACKGROUND AND IMPORTANCE Cavum septum pellucidum (CSP) and cavum vergae (CV) cysts are common incidental findings on imaging studies. However, they may rarely present with symptoms related to the obstruction of the foramen of Monro by the cyst leaflets. There is no consensus regarding the management of symptomatic CSP and CV cysts. We present an original transcavum interforniceal endoscopic fenestration technique. The step-by-step surgical procedure and two illustrative cases are presented. CLINICAL PRESENTATION A 31-yr-old male and a 24-yr-old woman presented with symptomatic CSP and CV cysts. For both patients, neuronavigation was used to plan the procedure. An endoscope was introduced into the cyst through a right frontal burr-hole. After an examination of the endoscopic anatomy, a communication between the cyst and the third ventricle was performed using an endoscopic forceps. In both cases, directly after the fenestration, cerebrospinal fluid (CSF) passed through the communication, and the collapse of the cyst was appreciated. Symptoms were relieved in both patients, and neuropsychological assessment improved. Postoperative imaging showed a reduction in the cyst bulge, and patent foramen of Monro. CONCLUSION Endoscopic fenestration of CSP and CV cysts to the third ventricle through an interforniceal navigated approach is a feasible and efficient surgical procedure. Theoretical advantages include a single tract through noneloquent brain, a perpendicular trajectory to the membrane for fenestration, and a large CSF space beyond the fenestration point.

Periaqueductal Tumor

Described by Dandy in 1921, the posterior interhemispheric transcallosal approach provides an operative corridor to the pineal region, posterior third ventricle, and upper midbrain. Intervenous-interforniceal and paravenous-interforniceal variants have been utilized for midline and paramidline pathology, respectively. The intervenous-interforniceal variant capitalizes on the natural separation of the internal cerebral veins, which are found medial to the forniceal crura at this level, to provide a safe corridor to the tumor while minimizing the risk of injury to the fornices. Here, the authors describe a posterior interhemispheric transcallosal approach using the intervenous-interforniceal variant for resection of a periaqueductal pilocytic astrocytoma.The video can be found here: https://youtu.be/mtQKEXEveTg.

AbstractA 24-year-old gentleman presented to us with complaints of occasional headache for 2 years. Magnetic resonance imaging showed enhancing supra sellar mass with nonenhancing cystic components, extending superiorly up to the body of bilateral lateral ventricle, laterally displacing septum pellucidum, and compressing the third ventricle with obstructive hydrocephalus. Hormone profile depicted adrenocorticotropic hormone <5.00 pg/mL, growth hormone 1.32 ng/mL, insulin-like growth factor-1 <3.0 ng/mL. The patient underwent surgical resection. Histological finding was suggestive of ganglioglioma World Health Organization grade I. Customized immunohistochemistry panel was advised and revealed positive CD 56, NSE, and GFAP immunohistochemical stains. Gangliogliomas are less frequent neoplastic lesions confined to only a handful of case reports and studies. Accounting less than 2% of intracranial neoplasms, these lesions primarily affect those in the first 3 decades of their life. As ubiquitous it is in nature, we hereby present a case of ganglioglioma in a young adult male arising from septum pellucidum.

Colloid Cysts

AbstractColloid cysts (CC) occur predominantly in the midline with majority involving roof of the third ventricle. In cases of cavum septum pellucidum (CSP), the surgeon can lose orientation when normal intraventricular structures are not encountered during surgery. We report a patient with CSP, who underwent right frontal parasagittal craniotomy, interhemispheric, transcallosal approach to reach the lesion. Lesion may not be seen in its usual location of foramen of Monroe, and entering the cavum may be confusing because no intraventricular landmarks will be seen. Excision of the cyst through the cavum usually requires interfornicial approach, and this structure must be separated gently to avoid injury.

The objective of the present work was to study the cerebral ventricles and its associated parts of brain of Surti buffalo (n=12), The cerebral ventricles included two lateral ventricles and third ventricle. The lateral ventricles were curved cavities presented large central part and three horns within the cerebral hemispheres. The third ventricle was an annular space on the periphery of inter-thalamic adhesion between two thalami. The mean length and width of central part of lateral ventricle were 4.78±0.07 and 1.49±0.07 cm, respectively. The septum pellucidum was thin translucent membrane of two laminae which separates two lateral ventricles. The mean values of length and height of septum pellucidum were 3.6±0.12 and 0.52±0.04 cm, respectively. The cavum septum pellucidum was a small space found between two laminae of septum pellucidum.
