“…It is expected that ETV would result in the communication between the intraventricular and subarachnoid spaces; however, the fenestration of all layers could potentially create a communication with the subdural space as well. Lamina terminalis fenestration is described as a viable alternative to ETV [ 17 ]. Anatomical studies have assessed the height (≈8.25 mm), the base (≈12.81 mm) and the area (≈52.84 mm 2 ) [ 18 , 19 ]; however, the diameter has not been appraised.…”

Background: Endoscopic third ventriculostomy (ETV) is an effective treatment for hydrocephalus. The in-depth understanding of microanatomy is essential for accurate diagnosis, treatment and complications prevention. The aim of this study is to supplement the knowledge gap regarding the microanatomical metrics and correlations for which the literature includes only scarce mentions at best. Methods: This is a descriptive microanatomical study including 25 cadaver brains. Specimens from donors with neurological, psychiatric disorders or alcohol abuse were excluded. Surgical loops were used for harvesting. High-precision tools were employed to dissect and measure the anatomical landmarks under a surgical microscope. Each measurement was performed in three consecutive attempts and outliers were rejected. RStudio was used for statistical analysis. Distribution was evaluated employing the Shapiro–Wilk test. Normally distributed values were presented as mean and standard deviation, and others as median and interquartile range. Results: The age of the donors was 61.72 (±10.08) years. The distance from the anterior aspect of the foramen of Monro to the anterior margin of the mamillary body was 16.83 (±1.04) mm, and to the posterior margin was 16.76 (±1.9) mm. The distance from the anterior mamillary body margin to the infundibulum was 6.39 (±1.9) mm, to the optic recess was 8.25 (±1.84) mm, and to the apex of the vertebral artery was 5.05 (±1.62) mm. The distance from the anterior commissure to the brain aqueduct was 22.46 (±2.29) mm, and to the infundibulum was 13.93 (±2.54) mm. The mamillary body diameter was 4.91 (±0.34) mm in the anteroposterior and 4.21 (±0.48) mm in the cranio-caudal plane. The intraventricular segment was protruding by 1.63 (±0.46) mm. The diameter of the hypothalamus on the anterior margin of mamillary bodies was 1.37 (±0.75) mm, of the Liliequist membrane was 0.19 (±0.07) mm and of the lamina terminalis was 0.35 (±0.32) mm. Conclusion: The presented microanatomical measurements and correlations are expected to contribute to the improvement of ETV safety.

“…Surgical removal of cysts and shunt insertion for fluid drainage may be necessary in cases of extensive infection, such as racemose NCC and severe extraparenchymal NCC 27 . Development of new techniques such as lamina terminalis endoscopic third ventriculostomy (LT‐ETV) may offer additional options for surgical intervention 37 . Careful patient selection and thorough preoperative evaluation are necessary to ensure optimal outcomes.…”

The ILAE Neuroimaging Task Force aimed to publish educational case reports highlighting basic aspects related to neuroimaging in epilepsy consistent with the educational mission of the ILAE. Neurocysticercosis (NCC) is highly endemic in resource‐limited countries and increasingly more often seen in non‐endemic regions due to migration. Cysts with larva of the tapeworm Taenia solium lodge in the brain and cause several neurological conditions, of which seizures are the most common. There is great heterogeneity in the clinical presentation of neurocysticercosis because cysts vary in number, larval stage, and location among patients. We here present two illustrative cases with different clinical features to highlight the varying severity of symptoms secondary to this parasitic infestation. We also present several examples of imaging characteristics of the disease at various stages, which emphasize the central role of neuroimaging in the diagnosis of neurocysticercosis.

“…6 A transventricular or subfrontal lamina terminalis fenestration is successful in 70% to 100% cases of hydrocephalus. 7-10 Extra-axial ETV (EAETV) can mitigate inherent issues with conventional ETV in managing SVS. We managed a 17-year-old young girl with SVS with an EAETV.…”
