Objective: To summarize the post-operative complications of resection of hypothalamic hamartoma (HH) through transcallosal transseptal interforniceal approach.
Methods: Thirty-seven HH patients, 26 males and 11 females, aged 8.7 underwent resection of the tumor via the transcallosal transseptal interforniceal approach. The symptoms and blood electrolytes were observed.
Results: After operation blood electrolyte test showed that 8 cases were normal, 19 cases showed hyponatremia as prime abnormality, and 10 cases had hypernatremia primarily. Among the 19 cases with hyponatremia transient apathy occurred in 2 cases, general epilepsy occurred in one patient, continuous minor epilepsy occurred in another one, 4 patients suffered minor epilepsy, 25 had fever the temperature of 3 of which were beyond 40 degrees C, and 2 had transient diabetes insipidus and 1 had diabetes.
Conclusion: Resection of HH through the transcallosal transseptal interforniceal approach achieves significant improvement of gelastic seizures with fewer complications. The most common complication is disturbance of serum natrium, which, however, is mild and well managed.

Colloid cysts of the third ventricle are benign intracranial lesions that account for 0.5 to 2% of all brain tumors and are even rarer in pediatric population. Dandy was the first to successfully excise a colloid cyst of the third ventricle via a transcortical transventricular approach in 1921.

Objective: Transcallosal transseptal interforniceal approach is recognized as the most appropriate route to resect sessile hypothalamic hamartomas but individuals with obliterated cavum septi pellucidi may pose difficulties to access these lesions safely.
Material And Methods: Six patients aged 8-34 years (med - 15.5) with the rather small (medial volume - 1.

Background: Hypothalamic hamartomas (HHs) are rare, and it is even rarer when combined with gray matter heterotopia (GMH) and polymicrogyria (PMG).
Case Description: A 5-year-old boy with HH, GMH, and PMG was retrospectively evaluated. The clinical data, including the symptoms, examinations, diagnosis, and treatment, were collected.

Background And Objective: To localize the human foramen of Monro stereotactically, to define the anatomical parameters of the safest stereotactic transcallosal transseptal interforniceal approach to the third ventricle, and to show how neurosurgeons could use them in preoperative planning.
Material And Methods: Our material consisted of 44 formalin-fixated human cerebral hemispheres. We found the location of the anterior (AC) and posterior commissure at the internal hemispheric surface.

Objectives A 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 possible trajectories to anatomical landmarks.
