Abstract null null Introduction null The third ventricular tumor is one of the most difficult lesions to approach. However, if a cavum septum pellucidum (CSP) and cavum vergae (CV) are present, approaching the tumor might be easier by exploiting them. Here, we describe the achievement of a favorable outcome in treating a patient with third ventricular tumor with CSP and CV using an anterior transcallosal interforniceal approach for tumor removal. null null null Case description null A 52-year-old woman presented with acute hydrocephalus symptoms. Head imaging revealed a tumor filling the third ventricle and protruding into the right lateral ventricle through the right foramen of Monro. We also confirmed the presence of CSP and CV. After ventricular drainage, we performed a craniotomy to remove the tumor via an anterior transcallosal interforniceal approach. Almost all of the intraventricular tumor was removed easily without any complications, such as memory impairment. null null null Conclusion null If CSP and CV are present, an anterior transcallosal interforniceal approach can be safely and effectively used to remove a third ventricular tumor.

Background Surgical treatment of brainstem cavernous malformations (CMs) remains a great challenge for neurosurgeons. Several cases published in the literature have addressed surgical approaches. However, no surgical approach has been reported to provide better exposure for CMs located in the superior midbrain. Methods We presented 10 cases of superior midbrain CMs in children treated in Beijing Tiantan Hospital from 2002 to 2016. The most common presenting signs and symptoms were hydrocephalus ...

Background Posterior third ventricular lesions often cause obstructive hydrocephalus. Thus, a combined endoscopic third ventriculostomy (ETV) and endoscopy biopsy are often the first treatment. However, the trajectories for both procedures can differ significantly, necessitating 2聽entry points or a combined rigid-flexible technique. Methods We describe the use of a large cavum septum pellucidum as a route for performing the biopsy. Results Using a rigid endoscope and a single trajectory, we were...

Abstract Objective Resection of tumors of the third ventricle through the transcallosal-interforniceal approach presents a surgical challenge with potential serious postoperative neurological deficits and complications. Retraction injury of the deep brain tissue and veins is a possible reason. Here, we aimed to investigate the feasibility and value of retractorless surgery in third ventricle tumor resection. Patients and methods Since 2014, a total of 31 patients with third ventricle tumors were...

Objectives鈥傾 plethora of surgical strategies have been described to reach deep-seated lesions situated within the third ventricle including the Rosenfeld, or transcallosal anterior interfoniceal (TAIF), approach. First introduced in 2001, it consists of a small callosotomy followed by the midline transseptal dissection of fornices to enter the roof of the third ventricle. The aim of this microsurgical anatomy study is to describe and show each stage of the surgical procedure, focusing on the pos...

Introduction Anterior midline intracranial cysts may be found most often in three forms: cavum septum pellucidum, cavum vergae, and cavum velum interpositum. A single offering that reviews these entities is difficult to find in the extant literature. Therefore, the present review was performed.

Object Pediatric pineal region tumors are very difficult to cure surgically. The authors used the transcallosal interforniceal approach in patients with these lesions. Methods One hundred fifty children, 98 boys and 52 girls, with pineal region tumors underwent tumor resection via the transcallosal interforniceal approach in the pediatric neurosurgery ward of TianTan Hospital. The patients ranged in age from 1 to 15 years. Fifty-eight patients had mature teratomas; 57, immature teratomas; 14, as...

Tumors located within the third ventricle have some potential limitations during surgical approach. Generally speaking, it is impossible to reach the third ventricle without incision of any neural structure. We report a patient with choroid glioma in the anterior part of the third ventricle, and coincident cavum septum pellucidum (CSP) in whom we could remove the tumor gross totally without damaging any neurovascular structures. The tumor expanded the space between the rostrum of the corpus call...

Object Intraventricular anatomy has been detailed as it pertains to endoscopic surgery within the third ventricle, particularly for performing endoscopic third ventriculostomy (ETV) and endoscopic colloid cyst resection. The expanding role of endoscopic surgery warrants a careful appraisal of these techniques as they relate to frequent anatomical variants. Given the common occurrence of cavum septum pellucidum (CSP) and cavum vergae (CV), the endoscopic surgeon should be familiar with that parti...

Background Despite their unfavorable locations, lesions of the third ventricle can be successfully removed via an interhemispheric, transcallosal approach. In cases with normal ventricular anatomy, this approach requires unilateral or bilateral identification of the foramen of Monro. Technique However, in the presence of abnormal ventricular configuration such as cavum septum pellucidum (CSP), this basic knwoledge needs to be modified. After routine callosotomy, there may be a confusion while en...
Increased prevalence of cavum septi pellucidi (CSP) in schizophrenic patients in comparison to healthy subjects was reported previously. Our purpose was to evaluate the prevalence of variants of the septum pellucidum in healthy subjects in three different age groups. 151 healthy subjects, including 46 children (age 6 卤 4 years), 72 young adults (age 31 卤 8 years) and 33 elderly adults (age 59 卤 7 years) were examined with high-resolution MRI. Three observers analysed the images using a standardi...
