“…Concerning the gender issue, it was previously reported that the height, anteroposterior diameter, and transverse diameter of the third ventricle were related to the individual anatomic variability of the skull shape and gender. Also, most published reports reviewed elsewhere reported that these morphologic parameters were greater in males [ 26 ]. Another study using other landmarks in MRI found no differences between genders except for the distance from the interforniceal insertion to the optic chiasm, which was greater in males [ 23 ].…”

Purpose Endoscopic third ventriculostomy (ETV) is a surgical procedure that can lead to complications and requires detailed preoperative planning. This study aimed to provide a more accurate understanding of the anatomy of the third ventricle and the location of important structures to improve the safety and success of ETV. Methods We measured the stereotactic coordinates of six points of interest relative to a predefined stereotactic reference point in 23 cadaver brain hemi-sections, 200 normal brain magnetic resonance imaging (MRI) scans, and 24 hydrocephalic brain MRI scans. The measurements were statistically analyzed, and comparisons were made. Results We found some statistically significant differences between genders in MRIs from healthy subjects. We also found statistically significant differences between MRIs from healthy subjects and both cadaver brains and MRIs with hydrocephalus, though their magnitude is very small and not clinically relevant. Some stereotactic points were more posteriorly and inferiorly located in cadaver brains, particularly the infundibular recess and the basilar artery. It was found that all stereotactic points studied were more posteriorly located in brains with hydrocephalus. Conclusion The study describes periventricular structures in cadaver brains and MRI scans from healthy and hydrocephalic subjects, which can guide neurosurgeons in planning surgical approaches to the third ventricle. Overall, the study contributes to understanding ETV and provides insights for improving its safety and efficacy. The findings also support that practicing on cadaveric brains can still provide valuable information and is valid for study and training of neurosurgeons unfamiliar with the ETV technique.

“…Numerous studies have concentrated on the investigation of the parameters of the third and fourth ventricles, as well as the lateral ventricles of the brain. The most valuable techniques are those that provide information from patient brain imaging studies [ 15 , 16 ]. There are studies that were conducted on the cadaveric brain, but we think that postmortem changes may suggest certain limitations to the data received from such specimens.…”

The evaluation of the different parameters of the brain ventricles is used in the diagnostics of age-related degenerative diseases of the central nervous system, as well as psychiatric disorders. The purpose of this study was to obtain data about the normal morphologic parameters of the lateral ventricles of the human brain and their relations with age and sex to establish a solid background for the diagnostics of any pathologic changes. Computed tomography (CT) studies of 108 healthy individuals aged from 17 to 86 (mean age: 46.87 ± 17.31) were selected for the study. The width of the different portions of the lateral ventricles was measured, and its relations with age and gender were assessed. The study has demonstrated a statistically significant dependence of the width of the different portions of the lateral ventricles on age. There was no statistically significant difference in this parameter identified between male and female groups. The width of the different portions of the lateral ventricles of the brain increases with age. Parameters are similar in males and females.

“…The sign of hydrocephalus is ventricular enlargement with some typical radiographic features, including dilated temporal horns, dilated third ventricle, rounded poster horns, thinned corpus callosum, and CSF extravasation [ 1 , 2 ]. However, ventricles of the human brain also enlarged with aging, neurodegenerative diseases, intrinsic and extrinsic pathologies [ 3 , 4 ]. The classical hydrocephalus diagnostic indicators have been widely used for a long time.…”

Background: The diagnosis of hydrocephalus is mainly based on imaging findings. However, the significance of many imaging indicators may change, especially in some degenerative diseases, and even lead to misdiagnosis. Methods: This study explored the effectiveness of commonly used morphological parameters and typical radiographic findings in hydrocephalus diagnosis. The patients’ imaging data were divided into three groups, including the hydrocephalus group, the symptomatic group, and the normal control group. The diagnostic validity and weight of various parameters were compared between groups by multiple machine learning methods. Results: Our results demonstrated that Evans’ ratio is the most valuable diagnostic indicator compared to the hydrocephalus group and the normal control group. But frontal horns’ ratio is more useful in diagnosing patients with symptoms. Meanwhile, the sign of disproportionately enlarged subarachnoid space and third ventricle enlargement could be effective diagnostic indicators in all situations. Conclusion: Both morphometric parameters and radiological features were essential in diagnosing hydrocephalus, but the weights are different in different situations. The machine learning approaches can be applied to optimize the diagnosis of other diseases and consistently update the clinical diagnostic criteria.
